Zool. 55: 1644-1649.C o~m o c c r c~l l a a r r o f~e~e n.sp. from Anofhecu spirrosn {Hylidae) oFMexico and thegenemtype C. haher; Steiner. 1914, from Hyla spp. (Hylid~e) of eastern North America are described. Cosmo~ercella anothecae n.sp. most closely resembles C. I~nhsri. These species differ in the number and arrangement of digitiform caudal papillae, shape of the gubernaculum. and size of spiczrles in males. Cosmocrrc~IIu Ituberi lacks the vesiculated 'bursa' mentioned in the original description and this character cannot be used to distinguish this genus. Cos~nocercelIo is characterized. however. by vesicularpd rosette male caudal papillae no1 present in other genera of Cosrnocercidae.
