标题：On the identities of Colostethus inguinalis (Cope, 1868) and C. panamensis (Dunn, 1933), with comments on C. latinasus (Cope, 1863) (Anura, Dendrobatidae). American Museum novitates ; no. 3444
摘要："For the past several decades, it has been thought that Colostethus inguinalis (Cope, 1868) (type species of Prostherapis Cope, 1868) is distributed in the Chocó region of western Colombia and throughout much of Panama. This study shows that C. inguinalis is a Colombian endemic known only from the lowlands of the Chocó and Magdalena Valley - an unusual distribution pattern among dendrobatids but one shared with a several other anuran species typically known from the Chocó region. Colostethus cacerensis Rivero, 2000 '1995' is argued to be a junior synonym of C. inguinalis. The available name for the tetrodotoxin-possessing species found in Panama is C. panamensis (Dunn, 1933), which is redescribed. The first record of C. panamensis in Colombia is also reported. Colostethus inguinalis and C. panamensis differ from each other in ventral coloration of adult males and adult females, flank coloration, head coloration, relative tympanum size, and mean adult female snout-vent length. Colosteth...
