摘要

The Pygopodidae is a near-endemic Australian family of limb-reduced, imbricately scaled gekkotans, cur rent- ly comprising 44 species (43 in Australia, 2 in New Guinea). Phylogenetic studies of the Pygopodidae have enlisted mo- lecular, mor phometric, and osteological methods to resolve intergeneric and interspecif ic relationships, however, only one publication details the morphology of pygopodid hemipenes, providing data on four species from three genera. Here, we augment these initial obser vations, by describing hemipenial condition in an additional 19 species across four gen- era, bringing current totals to 23 pygopodid species across five of seven recognized genera. Focused sampling of the genus Delma allows us to identify species groups based on hemipenial shape and ornamentation, and general morphology of cloacal spurs. We identify the presence of a single-lobed hemipenis in both Aprasia and Delma, and hypothesize this mod- if ication in reproductive anatomy has occur red twice independently in pygopodid evolution.
