Abstract

The robber fly fauna of the 6 subfamilies Apocleinae, Asilinae, Laphrinae, Ommatiinae,Stenopogoninae, and Trigonomiminae of Hispaniola with special reference to the DominicanRepublic is reviewed in light of new collections. This paper reports 6 genera (Cerotainia Schiner,Eumecosoma Schiner, Holcocephala Jaennicke, Pilica Curran, Proctacanthella Bromley, andRhopalogaster Macquart) new to the island, increasing the number to 20. Within the West Indies,Eumecosoma, Holcocephala, Pilica, and Proctacanthella are only known from Hispaniola. Also,33 species are reported, including 15 new species (Atomosia anacaona, A. ciguaya, A. jagua, A.jimagua, A. yurabia, Cerotainia sola, Eumecosoma caerulum, Holcocephala indigena, Ommatiusgeminus, O. laticrus, O. maculosus, O. praelongus, Proctacanthella taina, Plesiomma simile, andRhopalogaster albidus), increasing the number to 62 species plus 2 species in Dominican amber.The male of O. cinnamomeus Scarbrough & females of Plesiomma inflatum and Proctacanthusdarlingtoni Curran are reported for the first time. The Ommatius lucidatus species group isestablished with 8 extant and 2 fossil species. Plesiomma angustum (Macquart) and Atoniomyiamikii (Williston) are rediscovered and redescribed. Plesiomma lineata (Fabricius) is removed fromthe distribution list for Cuba and Jamaica and Neophoneus is removed from the list of West Indiesasilids because of an error in identification. Neophoneus flavotibis Bigot tentatively diagnosed asbelonging to the genus Efferia. Plesiomma macra Loew is removed from synonymy. Significantstructures of most species are illustrated and keys to selected species are included. At least onespecies of Atoniomyia and Pilica remain undescribed from this survey. New distribution records formost species and a checklist of the Hispaniolan fauna are also included.

Key words: Asilidae, new species, distribution records, Hispaniola

Introduction

The Hispaniolan asilid fauna, as well as all of the West Indies, have been sparselysampled, and are poorly known. Most new discoveries have resulted from systematicsurveys conducted over a period of years, such as those in Dominica and Hispaniola. Priorto 1900, Bigot (1875, 1878), Fabricius (1775), Johnson (1894), Macquart (1848), Olivier(1789), Walker (1885), Williston (1885, 1886) described the first 10 Hispaniolan species.Six species were added by Bromley (1928, 1931), Curran (1951), and Hull (1962) duringthe next 78 years for a total of 16 species. Subsequently, Scarbrough (1984,1997, 2001)and colleagues (Scarbrough & Poinar, 1993; Scarbrough & Perez-Gelabert, 2003, 2005)have added the remaining 46 species, plus 2 in Dominican amber, for a total of 20 generaand 64 species.

Of the 165 species recorded in the West Indies, 153 or 86% are endemic species. The


1381ZOOTAXA Greater Antilles, with the greater land masses and habitat types, have the vast majority of

species with 47 from Cuba, 62 from Hispaniola, 26 from Jamaica+Cayman Islands, and 24from Puerto Rico+Virgin Islands. Of these, eleven species, Andrenosoma chalybeum(Williston), Dasyllis cressa Bromley, Apachekolos clavipes (Johnson), Atomosiaincisularis Macquart, Efferia stylata (Fabricus), Cerotainia sola sp. nov., Leptogasterbahamiensis Scarbrough, L. obscuripes Loew, Ommatius lineolatus Scarbrough, O.marginellus (Fabricus), and O. setiferous Scarbrough, have been taken from 2 or moreislands. Shared species by country are: Cuba with 10, Hispaniola 5, Puerto Rico-VirginIslands 4, and Jamaica-Cayman Islands one. The Bahamas and Turks and Caicos Islandstotal 12 species of which 4 are taken from nearby islands or southeastern North America.The Lesser Antilles has 8 species with 2 shared.

This study reviews the asilid subfamilies Apocleinae, Asilinae, Laphrinae,Ommatiinae, Stenopogoninae, and Trigonomiminae from Hispaniola with specialreference to the Dominican Republic in light of new collections. Six genera new to theisland are reported and 33 species are reviewed, 15 of which are new to science. However,several species remain undiscovered or undescribed because males have not been found orthe genera are under revision. Furthermore, the asilid fauna is probably only 75–80%complete, especially considering that Haiti has been sparsely sampled with most speciesbeing taken in the southern areas.

Methods and materials

Descriptions are composites, based on all available specimens. Morphologicalterminology follows McAlpine (1981). Terminalia were treated in warm KOH, washed in70% ETOH and treated with a drop of acetic acid, transferred to glycerin, andsubsequently illustrated. Later, terminalia were placed in microvials with glycerin forpermanent storage and attached to the specimen pin. Penciled illustrations were scannedand completed using Adobe Photoshop software. Measurements were made using anocular micrometer in the eyepiece of a Meiji dissecting microscope. Body length wasmeasured from the foremost protrusion of the face to the apex of the terminalia. Winglength was measured from the articulated base to its apex. Data were recorded in astandard format with each line denoted by a forward slash [/] and a second label by an ~symbol, preceded and followed by a blank space. When these symbols appear on the datalabel, they are recorded without blank spaces. Spellings of locations on data labels arecorrected whenever possible, such as Monte Cristi=Montecristi. Countries appear only atthe beginning of a series in bolded, capital letters. Bold letters are also used to designateprovinces and types. Brackets [] denote useful additional information not found on labels.

Efferia Coquillett

Efferia Coquillett, 1893: 175. Type species: candida Coquillett (Coquillett, 1910: 536). Martin &Papavero, 1970: 62. Catalogue.

Nerax Hull, 1962: 476. Type species: Asilus aestuans Linneaus (orig. des.).Erax, authors, not Scopoli.

Remarks. This is one of the largest genera in the Americas with 118 named species (Martin& Papavero, 1970), and many more are undescribed. Of the described species, 18 are fromthe West Indies of which 4 are from Hispaniola. A revision of the West Indian Efferia isunder way (Scarbrough & Perez-Gelabert, in prep.) which attempts to establish thedistribution, identity and validity of several species. Efferia species inhabit open, sunnyareas usually perching on and foraging from bare soil and low ground objects, such asgrasses, fallen branches and trees, rocks, and shrubby woody plants.

Efferia fortis (Walker)(Table 1)

Erax fortis Walker, 1855: 623. Type locality: 'Santo Domingo', type: % (BMNH).

Efferia rufitibia (Macquart). Martin & Papavero, 1970: 65. Syn., New Comb. (Macquart 's Haitispecimens).

Remarks. Macquart (1848) described Erax rufitibia from two females from Brazil (RioNegro) and southern Haiti. Later, Walker (1855) described E. fortis from a male collectedfrom Santo Domingo and separated it from E. rufitibia largely based upon its hyalinewings. Curran (1953) recognized that Macquart 's type series consisted of two species andthe difficulty of identifying females, especially based upon Macquart's description. Heproposed that the name E. rufitibia be restricted to the Rio Negro specimen, leaving theHaitian specimen without a name. The latter was subsequently synonymized with E. fortis(Martin 1970).

Remarks. Efferia stylata was described in the genus Asilus and later transferred toEfferia. Presently it is reported as widespread in the West Indies. The identity anddistribution of the species is problematic since the type, a female, is essentially destroyed.No new records are reported here.

Proctacanthella Bromley

Proctacanthella Bromley, 1934: 96. Type species: Asilus cacopilagus Hine (orig. des.). Hull, 1962:498; Martin & Papavero, 1970: 82. Catalogue.

Remarks. Proctacanthella is a small genus thus far limited to western United States andnorthern Mexico (E. Fisher, pers. com. 2006). The 5 species in this genus are small tomedian size [11–25 mm] flies with a gradually inclined face, moderately produced

(Fisher, 1997). The anatergite is bare, vein R5 meets the wing margin below the apex, andthe female ovipositor is round in cross-section and bears a circlet of spines. Superficially,members of the genus are a smaller version of Proctacanthus Macquart [see remarkssection under this genus] but are distinguished from the latter by its smaller size, wingvenation and terminalia. Here we report the genus from the Dominican Republic for thefirst time.

1381ZOOTAXA December in Bahoruco and Montecristi provinces, Dominican Republic.

Etymology. Noun in apposition, taina referring to the species being an aboriginal ofthe West Indies.

Remarks. Proctacanthella taina is readily distinguished from the 3 Proctacanthusspecies by the gradually produced face, whitish vestiture of the body, and the combinedcharacters of the terminalia (Figs. 1–2). This is the first record of Proctacanthella in theWest Indies.

Proctacanthus Macquart

Proctacanthus Macquart, 1838: 120 (1839: 236). Type species: philadelphicus Macquart (Coquil-lett, 1910: 595). Hull, 1962: 487; Martin & Papavero, 1962: 77. Catalogue.

Remarks. A largely New World genus, only 6 WI species are known, and 3 of these arefrom Hispaniola. Here we add Azua, La Altagracia, La Vega, National District, Peravia,and San Cristóbal provinces in the Dominican Republic and Haiti to its distribution inHispaniola. The species are recognized by a large body (20–45 mm), abruptly producedface, long tapered abdomen that extends beyond the wings, and veins R4 and R5 meetingthe wing margin before the apex. Species perch on bare soil or low on vegetation.Ovipositors have conspicuous spines to deposite eggs in the soil.

Distribution. Cuba, Hispaniola, Puerto Rico. Captured during May, June, July, August-September from sea level-1150 m in elevation in Azua, Barahona, La Altagracia, HatoMayor, and Pedernales provinces in the Dominican Republic.

Remarks. Andrenosoma chalybeum is distinguished by the bluish-black ground colorand the straight proboscis with an obtuse apex (Fisher, 1986). All specimens examinedfrom the Dominican Republic and Puerto Rico fit the description of this species and is thefirst record of the species in the former location. Yet at least three size groups exists andprobably represent different species. The series from the Dominican Republic consist oftwo distinct size groups, one moderately large and the other much smaller. Furthermore,the specimens from Puerto Rico are much larger than any of those from the DominicanRepublic. Specimens from the Dominican Republic were captured on follen trees at ornear sea level in moist, deciduous forests in Azua, Barahona, La Altagracia, Hato Mayor,and Pedernales provinces of Dominican Republic and in Puerto Rico.

Distribution. Captured during June and July from sea level to 731 m in elevation inAzua, El Seibo, La Altagracia, Pedernales, and Santo Domingo provinces.

Remarks. Andrenosoma ruficaudum is distinguished by the reddish face, antenna, legs,and the apical 1/2 or more of the abdomen. It was captured near sea level in forests in theDominican Republic. The type locality of the species is Santo Domingo [province]. Itsdistribution now includes Azua, El Seibo, La Altagracia, and Pedernales provinces.

Dasyllis Loew

Laphria Loew, 1851: 20. Type species: Laphria haemorrhoa Wiedemann (orig. des.). Andrenosoma Martin & Papavero, 1970: 45. Dasyllis Hull, 1962: 358. Fisher, 1986: 105.

Remarks. This Neotropical genus currently consists of 26 medium-sized to large specieswith a black or reddish to yellowish integument (Fisher 1986, Fisher in press). The speciesare distinguished from all other Andrenosomini by the following combination ofcharacters: broad, wedge-shaped proboscis; proboscis apically parallel-sided, apex withdistinct V-shaped notch; gonostylus bilobed with longitudinal 'comb' of stout reclinatesetae, and usually preceeded by an apical tooth (Fisher, 1986). Only Dasyllis cressa(McAtee) from Cuba and D. rufa (Bromley) from Hispaniola occur in the West Indies. Dr.Eric Fisher, California Department of Food and Agriculture, Sacramento, CA, will report anew genus of ten species that includes the latter two species. As most Andrenosomini,


1381ZOOTAXA Dasyllis species inhabit mature forests. The immatures develop in fallen logs (Fisher &

Hespenheide,1992).

Distribution: Captured in April, June, and July at sea level to 800 meters in Azua, LaAltagracia, Pedernales, and Santo Domingo provinces. Fisher (1986) reported 2 specimensfrom Haiti.

Remarks. Dasyllis rufa is distinguished by its thick body, black antenna, broadproboscis, apex subrectangular with an apical notch. Its distribution now includes Azua,La Altagracia, and Pedernales provinces.

Neophoneus Williston

Phoneus Macquart, 1838:79 (1839:195) (preocc. Kaup 1829). Type species servillei Macquart .Neophoneus Williston, 1889: 255. New comb. Hull, 1962: 353; Martin & Papavero, 1970: 44.

Neophoneus is removed from the list of West Indies asilids because of an error inidentification in existing literature (Martin & Papavero, 1970). Bigot (1878) describedflavotibius from Haiti, probably placing it in Phoneus because Macquart's figure of thetype species, servillei, appears somewhat like a female Efferia. Bigot apparently did notrealize that Macquart’s genus was a Laphriinae. Diagnosis of P. flavotibius as a species ofEfferia is based on photographs of the type specimen (provided by J.M. Ayala), and theoriginal description of the species and figures provided by Bigot (E. Fisher, pers. comm.,2006). The status of the species will be determined following examination of the type P.flavotibius and a review of the species of Efferia from Hispaniola.

Pilica Curran, 1931: 20. Type species: Laphria formidolosa Walker (orig. des.) (1860: 280). Martin& Papavero, 1970: 43.

Remarks. This Neotropical genus, consisting of 11 described species, is distinguished by asharply pointed, usually upturned proboscis (Fisher pers. com.). This is the first report ofthe genus in the West Indies. Dr. Eric Fisher, California Department of Food andAgriculture, Sacramento, California, is revising this genus.

Subfamily Laphriinae

Tribe Atomosini

Atomosia Macquart

Atomosia Macquart, 1838: 73 (1839: 189). Type species: incisuralis Macquart (Coquillett 1910:512) = puella (Wiedemann).

Remarks. This large primarily Neotropical genus includes about 50 species. Previously,six species were reported from the West Indies, 4 from Cuba (Bromley 1929) and 2 fromPuerto Rico (Curran 1930). We report Atomosia from the Dominican Republic for the firsttime and 5 new species are described. The genus is distinguished by small robust bodies[5–12 mm], a strongly convergent vertex, and the antenna is without an apical style. Theflagellum is longer than the scape and pedicel combined and has a dorsal excised notch at


1381ZOOTAXA or beyond the middle that bears a minute spine-like bristle. The abdomen consists of 6

exposed segments with the sixth cup-shaped and concealing the terminalia. The dorsalsurface of the tergites is coarsely punctate (Hull 1964). Species are very similar and oftendifficult to separate. Identification of species relies heavily on color patterns of the cuticle,tomentum, and vestiture. Male terminalia thus far have not been studied extensively andare usually not illustrated. Species perch on sunlit rocks, trees, branches, and leaves, anderect objects such as dead or live tree trunks, sides of buildings and fence supports. Perchselection is documented in only a few species.

Distribution. Known only from type locality in Santiago province, DominicanRepublic. Collected at 515 meters in elevation, in April, from the trunks of palm trees.

Etymology. Named after Anacaona, also called 'golden flower', who was an Indian'queen' and wife of Caonabo, one of the five 'caciques' of the island of Santo Domingo.

Remarks. Atomosia anacaona is distinguished from congeners in the West Indies bythe black mystax wide yellow base of the hind femur, brownish-yellow basal tarsomere ofthe hind tarsus, and combined characters of the antenna and terminalia (Figs. 3–7). Thoughsimilar to A. parva Bigot (Bigot 1856, Bromley 1929, Curran 1935) in the black mystax,A. anacaona is distinguished by the yellow base of the femora and tibiae, the short stoutmarginal scutellar bristles which are about as long as the scutellum medially, the blacklateral scutal bristles, the white setose palps and thoracic dorsum, and the black setoseabdominal tergites. In A. parva, the face and palps are entirely black setose, the legs arelargely black, the scutellar bristles are much thinner and longer than the scutellummedially, the lateral scutal bristles are largely yellowish, only the notopleural bristle isblack, and the dorsum of the thorax and abdomen are yellowish setose.

Distribution. Independencia, Pedernales, and Peravia provinces in the DominicanRepublic and Departement / du Sud, Haiti. Collected in deciduous and pine forestsbetween 730 and 1440 m in elevation from July to September.

Etymology. From the Taino jagua, referring to the black color of aged fruit tree sap[jagua] that was used for body paint and dying cotton material. The name refers to theground color of this species.

Remarks. Atomosia jagua keys to A. danforthi Curran (1935) but is distinguished bythe 2 black ocellar dorsocentral setae and black lateral scutal bristles, reddish-brownpostalar callus, black legs, white setose body, and brownish-yellow or reddish base of thehind tarsus. It is similar to A. jimagua in the whitish setose dorsum of the thorax andabdomen but is distinguished by the characters above, those in the key, the long tergite 7,and by the combined characters of the flagellum and terminalia (Figs. 13–17). In A.jimagua, the sensory area on the flagellum is about 1/2 as long as flagellum, the spine-likedorsal corner of excised notch is as long or longer than the ventral spine, the legs are inpart yellow, tergite 7 is strap-like, about 1/4 as long as wide, the gonocoxa is narrowapically, the hypandrium is triangular, and the ejaculatory apodeme is capitate and stronglycurved forward (Figs. 19–22).

Distribution. Only known from the type locality, at 704 m in San Juan and Pedernalesprovinces.

Etymology. From the Taino language, yurabia for small place, alluding to the fact thatthe type series was captured at one location on the same day.

Remarks. Atomosia yurabia runs to A. rica (Curran, 1935) but is distinguished by itssmaller body (5.0–6.3 mm), swollen, wider, pedicel, which is about 2/3 as long as thescape, yellow scutal bristles, largely yellow femora, largely yellow setae on fore andmiddle tarsi, and combined characters of the flagellum and male terminalia (Figs. 23–27).Atomosia rica is a larger (6.5–8.0 mm) species with at least black notopleural bristles, andlargely blackish femora with only the basal 1/4 or 1/3 of the femora yellow. The apex ofthe gonocoxa is wider and rounded in lateral view, and the ejaculatory apodeme issignificantly wider on the apical 1/2. Contrastingly, the dorsum of the thorax and abdomenis whitish setose in the male (yellow in the female), apex of the gonocoxa is narrower,more pointed in lateral view and the ejaculatory apodeme is significantly narrower on theapical 1/2.

(aut. as mickii, err).

Remarks. This largely Neotropical genus consists of 16 species, one of which is Neartic(Martin & Papavero, 1970). It is distinguished by its small (6–7 mm) robust body, stronglypunctate scutum and abdominal tergites, short, appressed setae, and the terminalia areconcealed by the cup-shaped tergite 6. The flagellum has an apical, down-turned scapewith microsegment at its base. Species perch on soil near streams or low on vegetationnear ground level (Fisher and Hespenheide, 1992; Fisher, in press). We report 2 females ofan undescribed species and A. mikii (Williston) from Azua and Barahona provinces in theDominican Republic.

Distribution. Captured between 170 and 580 m in elevation during July and August inAzua, Barahona, and Santo Domingo provinces, Dominican Republic.

Remarks. Atoniomyia mikii is distinguished by the shape of the flagellum and lengthof the style (Fig. 28), anepisternum partly atomentose, the unusually long bristles on thetibiae and tarsi, and long setae laterally and brown setae medially on most tergites. Themale is further recognized by the combined characters of the terminalia (Figs. 29–32) andthe black setose, apically enlarged middle tibiae. Williston described A. mikii fromspecimens captured in Santo Domingo province. Azua and Barahona provinces are addedto its distribution. This is the first report of the species since the original publication in thelate 1800's.

Distribution. Barahona province, Dominican Republic. Remarks. Material of a second species captured in Barahona province is available but

only in the female sex. In addition, the flagellum is absent in both specimens. The speciesis distinguished from Atoniomyia mikii by its smaller body, entirely tomentose pleura,black tarsi, wing venation, and setation pattern of the body. Because the antenna is animportant element as well as male characters, especially the terminalia, in the diagnosis ofthe species, we leave it underscribed.

Rhopalogaster Macquart 1834: 279. Hull, 1962: 338; Martin & Papavero, 1970: 40.

Remarks. This Neotropical genus consists of only 7 species, one of which is reported fromCuba. Here we report the genus and a new species from the Dominican Republic for thefirst time. The genus is distinguished by its size (15–20 mm) laterally flat proboscis, shortpile, greatly reduced bristles, strongly constricted abdomen, and very long antenna. Thescape is usually 10 times as long as the pedicel, and the flagellum is 1.2–2 times the lengthof the scape and pedicel combined (Hull, 1962). Species inhabit mature forest below 1500meters, perching on shaded dead and live tree trunks (Fisher and Hespenheide, 1992;Fisher, in press).

Distribution. Known only from the type locality, La Vega province, DominicanRepublic.

Etymology. Latin albidus for 'gleaming or white' referring to the abundant, flat, whitesetae on the face.

Remarks. This is the first record of Rhopalogaster (Fig. 121) from the Dominican


1381ZOOTAXA Republic and the second from the West Indies. Rhopalogaster albidus is distinguished

from R. bella Bromley (1929) of Cuba by the long, flat, white setae below the antennaeand black setae on the dorsal 1/2 of the occiput.

Subfamily Ommatiinae

Ommatius Wiedemann

Remarks. This large, nearly world wide, genus inhabits mostly tropical regions. It is wellrepresented in the Neotropics with 100 varified species now reported. Of these, nearly 1/2(46) is from the West Indies, with 21 from Hispaniola, largely the Dominican Republic,and the remaining 25 the other islands. We also report the discovery of the male ofOmmatius cinnamomeus Scarbrough (1984) and illustrate its terminalia. The genus isdistinguished by the pectinate style. Many species prefer tips of bare branches of woody orherbaceous vegetation along margins of sunlit clearings in, paths and roads throughforested areas.

Distribution. Captured in montane forests between 1077 and 1270 mm in elevationduring July and August in La Vega and Santiago provinces.

Remarks. Ommatius bastardoanus is readily recognized by the unique terminalia,especially the somewhat truncate epandrium that bears a short, narrow ventroapical notch.Additionally, the strongly produced sternite 8 with a wide W-shaped apical margin andpyriform spermatheca distinguishes the female (Scarbrough & Perez-Gelabert, 2003). Thetype series were found in July. Here we extend its distribution to include Pedernalesprovince and the month of August.

Distribution. Captured in June and July at intermediate to high elevations (900 and2450 m) in National Park Armando Bermúdez, La Vega province.

Etymology. Latin geminus for twin, referring to the similarity of this species and O.praelongus.

Remarks. Ommatius geminus is distinctive from congeners by the characters in thekey, the largely black middle coxa, dense cluster of bristles in the apical corner of sternite6 (Fig. 53), the produced sternite 7, and the combined characters of the terminalia (Figs.59–66). Ommatius geminus is further distinguished from O. praelongus by the partiallyblackish metacoxa, shorter cell m3 (Fig. 46), the black palpus and proboscis, and sparseanepisternal setae. The male is also distinguished by the long sigmoid black bristle andgrooved yellowish callus on the fore femur posteriorly, 2–3 apical bristles on the hind


1381ZOOTAXA basotarsomere, and the numerous yellow bristles on tergites 3–5 laterally. In O.

praelongus, these characters are absent. The pale yellow callus is narrow and limited to thedorsal margin of the fore femur and a capitate bristle is present on the apex of the hindbasomere.

Distribution. Captured at intermediate elevations (1310 meters) during July inPedernales province.

Etymology. Latin adjective praelongus for 'elongated', referring to the long, narrow dand m3 cells of the wing.

Remarks. Ommatius praelongus is distinguished from congeners by the characters inthe key, the yellowish metapleuron and metacoxa, the posterior patch of long setae on theanepisternum, the exceptionally enlarged basal tarsomere and capitate bristle on the hindtarsus, distinctive vestiture of sternites 4–7 (Fig. 58), and combined characters of theterminalia (Figs. 83–90).

Ommatius lucidatus species group

The 4 new species, together with 4 earlier species (Scarbrough & Perez-Gelabert, 2003)and 2 extinct species (Scarbrough & Poinar, 1993; Scarbrough, 2001), form a distinctcluster of species here designated the lucidatus species group. The group is distinguishedby the following combination of characters; 1) slender body with thin legs; 2) face at thebase of the antenna >1/7 as wide as the head; 3) the fore femur (%) with pale yellowhooked setae posteriorly; 4) the tibial and tarsal bristles unusually long, at least 2/3 as longas the leg part; 5) the hind basotarsomere, sometimes the second basotarsomere, isswollen, about 1/4 wider than tarsomeres 3–5; 6) sternites 6–7 (%) with complex pattern ofrows and clusters of setae and bristles, bristles often compressed or close spaced formingdense mass or angular structures; 7) setae and bristles are often modified apically, i.e.pencil-shaped, only slightly tapered apically; hooked or angled about 45 degrees; apexround, not acuminate; capitate as a knob or flat horizontal plate; apex flattened vertically,wider than shaft and with notched apex; 8) gonostylus minute, aedeagus tubular,horizontal, slightly curved dorsally; 9) sternite 8 (&) longer than wide with medial fissureapically; and 10) the oval spermatheca. The following key will separate the known speciesof this group from the remaining Hispaniolan Ommatius species [see Scarbrough & Perez-Gelabert, 2003 for key]. Although members of this group are presently known only fromthe Dominican Republic, it is reasonable to assume that they occur across Hispaniola.

Remarks. Plesiomma angustum is distinguished from congeners by the characters inthe key, the proboscis is mostly yellow ventrally, and the combined characters of theterminalia (Figs. 91–97).

This is the first report of P. angustum from Hispaniola since its original description in1848. Although, the type specimen has been 'lost' (Martin & Papavero, 1970), thesespecimens have a quite narrow abdomen as its name implies. A comparison of theseHispaniolan specimens with valid West Indian Plesiomma species suggests that it isendemic to Hispaniola. Though we are uncertain of the type locality in Haiti (possiblyPort-au-Prince vicinity), new material adds La Altagracia, Montecristi, and Pedernalesprovinces, Dominican Republic, to its distribution. Collecting records suggest that itoccurs at low elevations (sea level to 700 m).

Distribution. Captured at intermediate and high elevations during May to July in LaVega, Preavia, San Juan, and Santiago provinces in the Dominican Republic and Haiti.

Remarks. As in the previous species, P. inflatum is endemic to Hispaniola. In contrast,it occurs at higher elevations (900–2009 m). The type locality, Mount Basil in northernHaiti, is approximately 1500 meters in elevation. We record the species in the DominicanRepublic for the first time. Here it is associated with dense secondary evergreen forestsand cloud forest in the Cordillera Central and the Sierra de Neiba mountains.

Plesiomma inflatum is distinguished from congeners by the dark, sooty body, swollenscape, and terminalia (Figs. 98–104). However, the male is usually significantly darkerthan the female. Abdominal tergites 2–4 of females are brownish-yellow or yellow withnarrow black lateral margins. Tergites 5–8 are usually progressively darker fromyellowish-brown to reddish-brown with the terminal segment darkest. The sides andnarrow apical margins are black. Plesiomma inflatum is most similar to P. funestum Loewin the black body. However, it is distinguished from the latter by the multiple rows ofbristles on the oral margin, the blackish legs, and combined characters of the terminalia(Figs. 98–104). Plesiomma funestum has a single row of sparse bristles along the oralmargin, the legs are entirely yellow, and the terminalia of the male is distinctive. Thesenew records extend the distribution of P. inflatum across Hispaniola.

Plesiomma lineata (Fabricius)(Table 1)

Asilis lineatum Fabricius, 1781: 465. Type locality: St. Croix, Virgin Islands, type: &? (ZMUC).Dasypogon lineatus Fabricius, 1805: 13.Plesiomma macra Loew, 1861: 35. Type locality: Cuba, type: %.Plesiomma lineata (Fabricius). Back, 1909: 307; Bromley 1929: 276; Hull, 1962: 219; Martin &

Papavero, 1970: 22. Catalogue.

Remarks. The identity of P. lineata is problematic because the type specimen is essentiallydestroyed, with only the thoracic dorsum surviving (Martin & Papavero, 1970). The


1381ZOOTAXAspecies has three easily recognized black stripes on the dorsum of the scutum. Thus,

museum specimens and authors usually identified specimens with such markings as P.lineata. Unfortunately, most of the West Indian species have these stripes. Hull (1962)grouped Plesiomma into the subgenera Boropis Hull, Dapsilochaetus Hull, andCystoprosopa Hull. Plesiomma lineata was designated the type species of Boropis Hull toinclude those species that lacked marginal scutellum bristles. Marginal scutellar bristles inthis genus are often thin [with small sockets], readily subject to being broken. AllAntillean species that we examined have marginal scutellar bristles. Bromley (1929)reported P. lineata from Cuba. Later, Farr (1963) reported it from Jamaica based onBromley's paper. Yet the type locality of Plesiomma lineata is St. Croix, Virgin Islands,'Habitat in Insula St. Crux Americes. Dom. Vahl.' (Fabricius, 1781; see Fabrician dipteroustypes in Thompson, 1981; Zimsen, 1964).

Bromley (1929) listed Plesiomma macra Loew as a synonym of P. lineata. The typelocality of the species is Cuba but its identity is also uncertain because the type is lost(Martin & Papavero, 1970). Furthermore, we have not located Bromley's specimens of P.lineata (=P. macra) from Cuba or Farr's P. lineata from Jamaica for study. Illustrations ofthe male terminalia of the Jamaican P. lineata distinguish it from the 3 Hispaniolanspecies. Since there are no authenticated records of P. lineata from Cuba, Jamaica, orHispaniola and its distribution is thus far limited to St. Croix, P. macra is removed fromsynonymy.

Distribution. St. Croix, U.S. Virgin Islands.

Distribution. Captured at low elevations during June and July in Barahona and SanCristóbal provinces.

Etymology. Latin simile for 'likeness or resemblance' referring to the appearance of thespecies in this genus.

Remarks. Plesiomma simile is distinguished from congeners by the characters in thekey, the reddish ground color and yellowish tomentum of the head, reddish wings, andterminalia (Figs. 105–111). It is further recognized by the absence of black vestiture.

Subfamily Trigonomiminae

Tribe Damalini

Holcocephala Jaennicke

Discocephala Macquart, 1838: 50 (1839: 166) (preocc. Laporte, 1832). Type species: rufiventrisMacquart, (Coquillett 1910: 534) = abdominalis (Say).

Holcocephala Jaennicke, 1867: 359 (nom, nov. for Discocephala Macquart). Type species: Disco-cephala rufiventris Macquart (aut.) = abdominalis (Say).

Remarks. This largely Neotropical genus is composed of small [4–8 mm], broad-winged,weak flying species. Species are distinguished by the wide, flattened head, reduced faceand frons, prominent goggle-like eyes and the thorax is strongly arched (Hull, 1962). Theyusually inhabit moist habitats, usually in diffuse light or shades of nearby forest margins,perching on the tips of vegetation. Here we report the first species in the West Indies.
