摘要
The Geckolepis fist-scale geckos, which exhibit extreme skin and scale autotomy, and are endemic to Madagascar and the Comoros, have long been cosnidered problematic concerning species recognition, with the last review of the group made by Angel (1942). Here we report the results of our morphological study, which examined 178 specimens representing most of the itnact museum specimens that are currently available. We find a total of three valid species within the genus Geckolepis: G. typica Grandidier, 1867; G. maculata Peters, 1880; and G. polyepis Boettger, 1893. We consider three previously descirbed taxa: G. petiti Angel, 1942; G. typica; and G. humbloti Vaillant, 1887, as a junior synonym of G. maculata. We designate MNHN 1994.1748 as the lectotype of Geckolepis typica. For each recognised species we provide a diagnosis and new description, summarize individaul variation, and descirbe geographical distribution. We also present an identification key for the group and discuss systematic and biogeographic issues and the unusual scale fragility of Gecklepis.
