ABSTRACT-The relationshipsbetween Kinosteron scorpioides and K. integrumare dis-cussed. A new allopatric pecies, Kinosternonaxacae, is described romcoastalOaxaca,Mexico.K.oaxacae is a memberof the scorpioides species complex(withntegrum), utdiffers rom hesetwo species in its reducedplastron,narrower arapace,and axillary nd inguinal cutes in broadcontact. A dichotomouskey forthe identificationf the adultKinosteron of Oaxacais presented.

INTRODUCTIONSystematic relationshipswithin he mud turtles(genus Kinosternon)f Mexicoare notoriouslyconfused. Several recent contributionsBerryand Legler1980; Conant and Berry1978; Iverson1978, 1979; and Iverson and Berry 1979) have clarifiedmany of the taxonomic problemsassociated withthe genus in northernMexico,butrelationships mongthe taxa insouthernMexicoremainin disorder.Particular isagreementsurrounds he systematicrelationships etween KinosternonntegrumLeconte and K.scorpioides Linnaeus(K.cruentatumDumeril nd Bibronn Dumeril nd Dumeril1851 has been relegatedto a subspecies of K.scorpioides by Legler1965 and Iverson1976).Siebenrock (1906, 1907) was first to consider integrum'a subspecies of K. scorpioides, an

arrangementfollowedsubsequently by Ahl (1934), Wermuthand Mertens(1961, 1977), CasasAndreu (1967), and Morafka 1977). Mostotherauthors(e.g. Smith and Taylor1950; Duellman1961; Casas Andreu1965;Hardy nd McDiarmid969;Pritchard979;andSmithand Smith1980)have consideredintegruma species distinct rom corpioides.Pritchard1967)referred o integrumas a subspecies of scorpioides in his text (p. 40), but as a distinct pecies in his index(p. 285).We have examined the relationshipsbetween Kinosternonntegrumand K. scorpioides indetail. The two taxa are knownto occupythe same riverbasins only in the Rio Panucoand RioPapaloapan basins in eastern Mexico.Although hey are nowhere knownto occur at the samelocality,we findthe lackof evidenceof intermediacyintergradation)nd the presenceof numerousmorphologicaldifferencesbetweenthe taxa to be ampleevidence thatKinosternonntegrum s a1Present address:Department f Biology,Elmhurst ollege,Elmhurst,llinois 0126.2Present address:Department f Biology,EarlhamCollege,Richmond,ndiana 7374.30rder of authorshipwas determinedby the toss of a coin.1980 JOURNAL OF HtnrtlOLOGY 14(4):313-320 313

We cannot agree withMorafka's1977) suggestionthat ntegrums a "Mexican ighplateaurace of scorpioides" ince itoccupies lowlandhabitatsvirtuallyo sea levelalongmuchof the PacificCoast of westernMexico(albeit t is restrictedo the MexicanPlateau neasternMexico; n this,cf. Iverson ndBerry1979).The relationships mongall membersof the Kinosternoncorpioidescomplex includingntegrum)are discussed by Berry 1978).In examiningthe distributions f K. scorpioides cruentatumand K. integrum n southernOaxaca, Mexico where theirgeographicranges are adjacent,we discovered he existence of athird,undescribed,allopatric pecies of Kinosternon.
