REVISED CHECKLIST OF NORTH AMERICAN MAMMALS

NORTH OF MEXICO, 1986

J. KNOX JONES, JR., DILFORD C. CARTER, HUGH H. GENOWAYS,

ROBERT S. HOFFMANN, DALE W. RICE, AND CLYDE JONES

For more than a decade, we have periodically updated achecklist of scientific and vernacular names of species of NorthAmerican mammals (Jones et al., 1973, 1975, 1979, 1982). Suchchecklists provide a ready reference for many scientific endeavors,both in the field and in the laboratory, and are particularly usefulto students. Since publication four years ago of the most recentrevision of the list, demand for copies has severely depleted theoriginal supply. Moreover, many significant taxonomic andnomenclatorial changes have appeared in the primarymammalogical literature since March of 1982. In this version ofthe checklist, we have attempted to include all species of Recentmammals, a few of which now may be extinct, occurring inNorth America (and its adjacent waters) to the north of Mexicoand recognized in publications through May of 1986. Our listrepresents a consensus among the six authors but does notnecessarily imply complete agreement among them on allcontroversial points. Some suggested changes that have not beenadopted are discussed in the text preceding the checklist.

As most readers are aware, a number of species of mammalsnot native to North America have been introduced there over theyears. Thirteen such taxa (four more than in 1982) are includedin the checklist (identified by an asterisk) because they now occurin the wild state in numbers sufficient to justify listing them.Other exotic species possibly will be included in subsequent lists.

DEPARTURES FROM JONES ET AL. (1982) AND

OTHER NOTES

We have documented below those instances in which scientificnames used in this checklist differ from those used by Jones etal. (1982). Some other pertinent comments are included that mayhelp to explain the current list of recognized taxa.

Marsupials

We here retain Marsupialia as the ordinal name for this group,following Marshall (1984), because no clear consensus yet hasevolved as to an acceptable higher classification for thesemammals. Some authors (Strahan, 1983, for example) place NewWorld marsupials in the order Polyprotodonta, whereas others(Woodburne, 1984, for example) use Didelphiformes. Most recentworkers agree that two or more groupings of marsupials aredeserving of ordinal rank, but there is no debate that the totalassemblage comprises a monophyletic unit. Archer (1984) hasprovided a useful historical summary of marsupial classification.

Insectivores

In this group, the only changes involve species of the genusSorex , although some specific distinctions among Blarina remainto be clarified. Sorex fontinalis (Kirkland, 1977; Junge andHoffmann, 1981) provisionally is recognized as a species distinctfrom S. cinereus as is S. haydeni (van Zyll de Jong, 1982, 1983).We also have followed van Zyll de Jong (1983) in recognizingboth Sorex ugyunak and S. jacksoni as distinct at the specieslevel, but suggest that they ultimately may prove to be conspecific(van Zyll de Jong, 1982).

While we continue use of the name Sorex hydrodromus for theshrew of the Pribilof Islands, we acknowledge that van Zyll deJong (1982) has called this usage into question. Finally, we nowfollow the tentative arrangement of Junge and Hoffmann (1981)in regarding Sorex alaskanus as a synonym of S. palustris.

Bats

That Myotis keenii as recognized In the past might representtwo species first was proposed by van Zyll de Jong (1979). Thesame author (1985) now has provided additional data thatindicate M. septentrionalis is distinct from M. keenii. Similarily,van Zyll de Jong (1984, 1985) has shown that the eastern and

JONES ET AL.-NORTH AMERICAN MAMMALS 3

western populations of small-footed myotis (Myotis leibii and M.ciliolabrum, respectively) ought to be regarded as separate species.

Edentates

Although it is not altogether clear how the ordinal-group nameEdentata Cuvier, 1798, should be applied or even what itincludes, most recent American authors (Barlow, 1984; Dawsonand Krishtalka, 1984; Gingerich, 1984; Glass, 1986) have used thename Xenarthra Cope, 1889, for the New World "edentates." Wefollow them.

Lagomorphs

We elevate Brachylagus to full generic standing followingDiersing (1984) and earlier Dawson (1967).

Rodents

Sciuridae.-Based on additional data (Levenson et al., 1985),we continue to regard Tamias as the single generic name forchipmunks. Following the same authors, we now consider T.senex and T. siskiyou, and inferentially also T. ochrogenys, assubspecies of T. townsendii (see also Levenson and Hoffmann,1984), although as yet unpublished data on alarm calls suggestcontinued separation. Patterson (1984) provided evidence forrecognizing T. rufus as a species different from T. quadrivittatus(but see his discussion of application of the name hopiensis). Wehave not followed Nadler et al. (1982) in elevating Spermophilustownsendii mollis and S. t. vigilis to specific rank.

Geomyidae.-Bohlin and Zimmerman (1982) and Cothran andZimmerman (1985) have shown that Geomys breoiceps differsfrom G. bursarius in a variety of ways and is deserving of fullspecific status; conversely, Hafner and Geluso (1983) reduced thetwo races of Geomys arenarius to subspecies of G. bursarius,although this interpretation is deserving of further analysis. Onthe basis of genic differences, Honeycutt and Williams (1982)again elevated Cratogeomys to generic status (from Pappogeomys).

Heaney and Timm (1983, 1985) provided evidence that geneflow is extremely limited between eastern (bursarius) and western(lutescens) populations of the plains pocket gopher, and regardedthe two as separate species. However, Burns et al. (1985) assessedthe data differently. As the controversy continues, we adopt theconservative stance and continue to recognize only one species onthe northern and central Great Plains.

4 OCCASIONAL PAPERS MUSEUM TEXAS TECH UNIVERSITY

Heteromyidae.-Following Hafner and Hafner (1983) andothers, we recognize Chaetodipus as the generic name for allspiny-rumped pocket mice, including C. formosus (Patton et al.,1981).

Cricetidae.-Among the sigmodontines, we follow Modi andLee (1984) in submerging Peromyscus comanche as a subspeciesof P. truei and the same authors in elevating P. gratus to specificstatus. We also follow Gunn and Greenbaum (1986) inrecognizing Peromyscus oreas as distinct from P. maniculatus.

Among the arvicolines, we agree with Carleton and Musser(1984) that Arborimus should not be recognized as a genusdistinct from Phenacomys and that Lemmiscus should replaceLagurus as the generic name for the sagebrush vole. We alsoregard Microtus breweri and M. nesophilus as insular subspeciesof M. pennsylvanicus and M. coronarius as an island race of M.longicaudus.

As for use of the generic names Pitymys and Pedomys, wehonestly do not know what to do; consequently, we have donenothing. Anderson (1985) did not recognize these at the genericlevel nor did Carleton and Musser (1984) or Hoffmann andKoeppl (1985). Paleomammalogists (Repenning, 1983, andZakrzewski, 1985, for example) generally recognize Pitymys, mostregarding Pedomys (for M. ochrogaster) as a synonym thereof.Repenning (op. cit.) even recognized pinetorum and nemoralis asdistinct species in Pitymys. At this juncture, is seems best tofollow Carleton and Musser (1984) and Anderson (1985) inreferring all these voles to Microtus.

We have not followed Koeningswald and Martin (1984) inelevating Mictomys to generic standing for the northern boglemming. As for Dicrostonyx, the substantial chromosomalvariation within the genus seems to indicate that as many asseven species of Pleistocene derivation inhabit Arctic America(Rausch and Rausch, 1972; Rausch, 1977; Krohne, 1982) andthese are provisionally admitted here (see also Honacki et al.,1982). For Lemrnus, we continue to follow Rausch and Rausch(1975) in recognizing but one species in North America, L.sibiricus.

Muridae.-Although we continue to use Mus musculus as thespecific name of the house mouse, it is worthy of mention thatrecent studies (Marshall, 1981; Marshall and Sage, 1981) suggestthat M. domesticus may be the species introduced into the NewWorld.

JONES ET AL.-NORTH AMERICAN MAMMALS

Carnivores

5

We have not rearranged the families of Carnivora, butacknowledge that familial relationships among pinnipeds andterrestrial carnivores remain problematical (Wiig, 1983).Similarily, we retain the generic name Felis for all included catswith the realization that there is considerable disagreement onthis matter in recent literature (see Groves, 1982, and Newman etal., 1985, for example). At the extreme, four different genericnames are recognized for species listed here: Panthera (onca),Puma tconcolor, yagouaroundi) , Leopardus (pardalis, wiedii),and Lynx (lynx, rufus).

An analysis of phocids by Muizon (1982) indicated that Phoca(sensu lato) is a paraphyletic assemblage and that Pusa,Pagophilus, and Histriophoca should again be regarded as fullgenera (see also Hall, 1981).

Whales

Following Barnes (1984a), the Odontoceti and Mysticeti areagain reduced to subordinal status under the single order Cetacea.Also, in accord with findings of the same author (1984b), thepygmy sperm whales are again accorded full familial rank(Kogiidae).

The International Commission on Zoological Nomenclaturehas placed Mesoplodon on the Official List of Generic Names ofZoology (Opinion 1289). Furthermore, the Commission has beenpetitioned (Rice, 1984) to conserve the specific name truncatus (inTursiops as used here) and to suppress the name nesarnack. Inaccordance with Article 31(b) of the new edition of theInternational Code, the correct spelling of the specific name forthe long-finned pilot whale must be melas, as originallyproposed, not melaena. We have not accepted the proposal ofBarnes and McLeod (1984) to place the blue whale in themonotypic genus Sibbaldius Flower, 1865, because that name isan invalid emendation of Sibbaldus Gray, 1864, the type speciesof which is the sei whale, and because such placement would, inour view, obscure its relationship to the remaining four speciesof Balaenoptera. And finally in nomenclatorial matters, wecontinue to use the specific name macrocephalus for the spermwhale (Husson and Holthuis, 1974) because Schevill's (1986)rejection of that name in favor of catodon was based on amisinterpretation of the International Code.

Perrin et al. (1985) revised the spotted dolphins (Stenella) andfound S. plagiodon to be a synonym of S. frontalis, and Hershand Odell (1986) added Lagenodelphis hosei to the list of NorthAmerican cetaceans based on a mass stranding at Marquesas Keys,Florida.

Artiodactyls

Four new exotic species have been admitted to our checklist onthe basis of several recent publications.

CHECKLIST

As in previous lists, orders, families, and genera are listed inconventional phylogenetic sequence mostly following Hall (1981)but, in a departure from previous lists, species are enteredalphabetically within each genus. While this may prove annoyingto some professional mammalogists, it will facilitate use of thechecklist by those unfamiliar with intrageneric taxonomy, andsome assemblages really are not well enough understood to createa meaningful hierarchy at the specific level.
