associated with true cave waters. Pearse and Wilson(1938) reported Nitocrella subterranea (Chappuis)from Grutas de Balankanche, Yucatan, but this UnitedStates species may bc misidentified.Family CanthocamptidaeTwo genera of canthocamptid copepod have beenrecorded from \Iexican caves. Canthocamptus sp. wasidentified from Cueva de Los Sabinos, San Luis Potosi,by Osorio Tafall (1943). Attheyella pilosaChappuis was reported by Wilson (1936) from CuevaLuchil, Yucatilll, and is listed by Nicholas (1962) asa troglobite. This species is a commensal of crayfishesin Kentucky and Indiana and furthermore occurs oncrayfish in an epigean locality in Kentucky (Bowmanet aI., 1968). Nicholas (1962) also lists Moraria cristataChappuis as a troglobite from "unnamed cave atCienga, near Progreso, Yucatan." This species wastaken from a cienega (a large open pond) and not acave.Subclass OstracodaOrder PodocopaThe ostracods of J\lexican caves are very poorlyknown. A total of 25 species have been identified,but eight are known only from open-air cenotes inYucatan and 12 are commensals on crayfish and isopods(see Table 10). The remaining five species surelyconstitute a very small percentage of the free-livingostracods inhabiting caves in ;\'Iexico.Family CypridaeOsorio Tafall (1943) reported Candona sp. andCypris sp. from caves near Valles, San Luis Potosi.Furtos (1936, 1938) described Cypridopsis inaudita,C. mexieana, and C. yucatanensis from caves in Yucatan.Chlamydotheea areuata (Sars) has recently beencollected from Cueva de EI Pachon, Tamaulipas.None of these show any signs of adaptation for a caveexistence.Family DarwinulidaeThe only species of this family reported from subterraneanwaters is Darwinula stevensoni (Brady andRobertson); it was found in Cenote Xlaka, Yucatan(Furtos, 1936).Family EntocytheridaeTwelve species of entocytherid ostracod, two ofwhich are troglobites and commensals of cirolanidisopods, have been collected from Mexican caves. Theremaining species are all associated with crayfish. Hartand Hart (1974) in a review of the family have includedall synonymies and records. Ankylocytherebidentata (Rioja) is known from caves in Chiapas,Oaxaca, and Veracruz; A. maya Hobbs from caves inOaxaca; A. sinuosa (Rioja) from Cueva Chica, SanLuis Potosi; A. tolteeae Hobbs from caves in Hidalgoand San Luis Potosi; A. villalobosi Hobbs from Grutasde Zapaluta, Chiapas; and Entocythere claytonhoffiRioja from caves in Chiapas, Oaxaca, and SanLuis Potosi. Entocythere mexicana Rioja, Uncinoeytherebieuspida (Rioja), U. euadrieuspida (Rioja),and U. dobbinae (Rioja) have all recently been foundin caves in the Cuetzalan region of Puehla.Sphaeromieola cirolanae RiojaSphaeromieola cirolanae Rioja, 1951a: 170-179, fig.1-16; Rioja, 1953a:289-290, 291, 292; Levinson,1959:259; Nicholas, 1962:168; Hart, 1962:122,139; Vandel, 196-1-:303; Vandel, 1965a:254; Reddell,1967b:82; Reddell, 1971b:lB: Hobbs, 1971:2,3,7,8-9,45-47, fig. 30-31; Reddell and l\litchell,1971a: l-I-2; Hobbs and Hobbs, 1973:39-41,fig. la, b; Reddell and Elliott, 11)73a:17]-172;Reddell and Elliott, 1973b:181, 18:3; 1I01t, 11)73:4; Hart and Hart, 1974:15,164-165, pI.
