and O. vandalitiae (Kraatz, 1868) from southernIberian Peninsula.

Recent papers on European Osphya have describedin detail the differences among most of the species,notably the morphology of tergite and ventrite Vand/or apex of aedeagus of O. bipunctata, O. brusteli,O. lehnertae and O. aeneipennis (Gourves and Brustel,2001; Konvicka, 2014, 2016b).

Conversely, papers dealing with the morphology ofO. vandalitiae are almost restricted to XIX centuryworks related with its description and identification asgood species (Kraatz, 1868; Uhagón, 1887; Seidlitz,1896) and mainly focused on size, un-thickened legs,elytral gloss, pubescence, and some other chromaticaspects. We do not know any subsequent significantdata. Also the distribution of the species is mainlybased on old and scarce records (see compilations in:Fuente, 1933; Recalde Irurzun and Pérez Moreno,2011). Therefore, O. vandalitiae still remains being anot well known species.

Osphya vandalitiae: History

of its discovery and original

description

In the volume 9 of Berliner Entomologische Zeitschrift,H. von Kiessenwetter relates that not less than20 French and German entomologists agreed andparticipated on entomological explorations in Spainduring the year 1865. The German team includedKiessenwetter himself, G. Seidlitz, H. Kraatz, H. Cle-mens Müller and H. Graf von Hoffmannseg. Theirexcursion started in spring and they mainly concen-trated their activities in different areas of Andalusia.In the page 385, von Kiessenwetter mentions thecatch of some individuals of Osphya that refers toO. aeneipennis Kriechbaumer [1848] (Kiessenwetter,1865; Seidlitz, 1896). More details of the catches are:Granada, on May the 21th, outside the walls of LaAlhambra, Darro valley on the way to «fuenta de losavellanas», on deciduous shrubs (Kiessenwetter, 1865;Kraatz, 1868; Seidlitz, 1896).

It appears that the whole group was present that day.Anyhow, Kraatz seems to have kept some individuals(Kraatz, 1868; Gaedike, 1986: 2 syntypes, Granada,Kraatz leg.), and probably also Seidlitz (Seidlitz, 1896:1 male, 2 females).

Few years later Kraatz (1868) wrote on the variabilityand differences of the European Nothus Olivier, 1811

(= Osphya Illiger, 1807) known until that time (bipunc-

tata, aeneipennis and the individuals from Andalusia).In those years, the real or supposed variability ofO. bipunctata and O. aeneipennis had led to consider thepossibility of unifying the forms of Osphya under oneor two species. Kraatz did not share such opinionand proposed, cautiously, the name vandalitiae forthe Andalusian forms («...which can remain even if itturns out later the necessity of an unification»).

«Nach alledem wage ich es noch keineswegs, all drei oder nur

zwei von den besprochenen Formen zu vereinigen, und schlage

für die andalusische den Namen Vandalitiae vor, welcher ihr

auch bleiben kann, falls sich später die Nothwendigkeit einer

Vereinigung herausstellen sollte.» (Kraatz, 1868).

Hereinafter we extract the main points of the unusualdescription of O. vandalitiae by Kraatz:

«[...]. The largest specimens of the Andalusian Nothus are

about as big as the smallest of the bipunctatus, [they] are

cylindrical, with much of the elytra and the abdomen punctured.

The elytra are beautiful metallic green and grey haired; the grey

hairs are stronger along the suture and on the outward half of

the elytra and weaker on the apex [...]». «Spanish specimens

with thickened legs, so far as I know, have not been captured

by us». «[...] [the pronotum edge] being reddish everywhere in

my Andalusian [specimens]».

Some years later, in the fifth volume devoted toColeoptera of Naturgerchichte der Insecten Deutschlands,Seidlitz (1896) regards O. vandalitiae as a good speciesand clearly separates it from O. bipunctata and O. aenei-

pennis because of the morphology of the pronotum,among other characters.

Material and methods

Recorded individuals of Osphya species from newlocalities were mainly found by direct collecting onshrubs or beating flowery bushes (as for exampleCistus sp. and Crataegus sp.), and more rarely by flightinterception traps. Conopalpus species records are basedon individuals trapped using window, multi-funneland baited-aerial traps.

As far as we know, no concrete new records of O. van-

dalitiae have been published since the XIX century.Next, we provide a list of new localities based on asignificant amount of specific records from Spain andPortugal (map of Fig. 7a).

normal (un-thickened) femora. The color of elytra isnormally green-blue or blue metallic. Two out ofseventy individuals (both of them females) showorange-brown colored head, pronotum, legs andelytra (Fig. 1c).

Iberian Osphyinae

The Iberian Osphyinae is a small group of falsedarkling beetles (two genera and five species) but sofar little studied. Both the Iberian-Balearic and thePalaearctic catalogues (Fuente, 1933; Nikitsky andPollock, 2008) mention two/three species from Spainand/or Portugal: Conopalpus brevicollis Kraatz, 1855,Osphya vandalitiae (Kraatz, 1868) and Osphya bipunctata

(Fabricius, 1775). In the last years, and as a result ofseveral field studies focused on the fauna of saproxylicbeetles, two additional species have been discoveredin Spain (Conopalpus testaceus (Olivier, 1790) and Osphya

aeneipennis Kriechbaumer, 1848); moreover, Osphya

bipunctata, a doubtfully recorded species from theIberian Peninsula, has been found in the last decadein a bunch of localities of the Pre-Pyrenean andBasque Mountains, as well as in central and northernIberian mountain ranges (e.g.: Recalde Irurzun andPérez Moreno, 2006, 2011; De la Rosa, 2013; Viñolaset al., 2014).

Recorded localities of the regions or provinces whereevery species is known to occur are compiled in thefollowing chronological checklists:

C. brevicollis appears to occur in most part of theIberian Peninsula, associated to forests of deciduous(map of Fig. 7b). Based on our experience in theregion of Navarre (north Spain), it is a never frequentbut widespread element present in Atlantic, sub-Me-diterranean and supra-Mediterranean Iberian forests.Its occurs in southwest Europe, from Portugal untilwest Balkan Peninsula. It is also present in southGermany (Nikitsky and Pollock, 2008) and there isone old record from Austria (Konvicka, 2016a).

In Spain it occurs in northern wet forests of deci-duous and in some areas of the Central Iberian Rangewhere the populations of C. testaceus are probablyscattered and/or isolated (map of Fig. 7c). C. testaceus

is a widely distributed European species (Nikitsky andPollock, 2008).

NOTE: According to Viñolas et al. (2014) the Kiessen-wetter’s record should be found in the province of Jaen(not in Granada). Although very probably O. vandalitiae

occurs in Jaen, Kiesenwetter says «In dem Darrothalle auf

dem Wege nach der Fuenta de los avellanas» and, for sure, refersto a route near the Alhambra de Granada where it exists

a popular fountain called «Fuente del avellano» that someforeign travelers mentioned as «Fuente de los avellanos»(e.g.: Ford, 1847). All in all, both Kraatz (1868) and Seidlitz(1896) also clearly stated that the catches took place inGranada, not far from the Alhambra.

All the known records of this species are fromsouthern areas of Spain and Portugal (map ofFig. 7a).

The Iberian distribution of O. bipunctata is probablysimilar to that of C. testaceus: moist northern forestsof deciduous (Montseny range, Urbasa-Andía-Entziarange, Pre-Pyrenean mountains, northern Iberianrange) plus, probably scattered, populations in somemountains of the Iberian interior (map of Fig. 7d).In the north of Navarre it is not a rare species and

PREVIOUS RECORDS: Spain. Barcelona: Saldes (Viño-las et al., 2014).

This species occurs in south-east France, southSwitzerland, Austria and north Italy (Nikitsky andPollock, 2008; Brustel, 2014; Andreas Sánchez, com.pers.). French records from eastern Pyrenees areasare restricted to the comarca of The Conflent(Department of Pyrénées Orientales: Brustel, 2014).

Two years ago a female of O. aeneipennis was re-corded from east-Pyrenean mountains, in the northof the Spanish Catalonia (Viñolas et al., 2014) (map ofFig. 7c).

Key to the Iberian Osphyinae

Soft bodied elongate beetles, somehow resemblingCantharidae. Some species show green or bluemetallic colored elytra while others can be yellowishto rusty brown or blackish. Antennae long and fili-form. Head distinctly narrowed behind the eyes.Tarsal claws strongly toothed. Larvae with stronglycleft maxila and a chitinized dorsal bulge on the ninthabdominal segment (Viedma, 1965; Crowson, 1966).
