Yakushima Gecko

Yakushima Gecko (Gekko yakuensis) is a Japanese member of the Gekko japonicus species group. Accessible summaries do not expose a full diagnostic description, so colour and measurements are not supplied here; reliable identification requires comparison of detailed scale characters with Hokou Gecko and other closely related Japanese Gekko rather than reliance on island location alone. Identification should use the full combination of documented structure, pattern and locality because closely related island forms may overlap in general appearance (Wikipedia, general species account; Reptile Database).

The species is endemic to Japan and is documented from Kyushu and the north-eastern Ryukyu Islands, including Yakushima and Tanegashima; its type locality is Anbo on Yakushima. It lays eggs and occasionally hybridises with Hokou Gecko where their ranges meet, producing mosaic hybrid zones in southern Japan (Reptile Database; Wikipedia, general species account). The description stays within species-level information available from the opened accounts; traits not documented there are omitted rather than transferred from related lizards (Wikipedia, general species account; Reptile Database).
