Goniurosaurus orientalis
Rare visitor: recorded only occasionally in this country
Spotted Ground Gecko (Goniurosaurus orientalis) is a dark brown or black eyelid gecko patterned orange or red, with deep red eyes, functional eyelids and a total length reaching roughly 16 cm. Identification should combine documented pattern, scalation, body form and locality because related Japanese reptiles may be very similar. Claims here are limited to the opened species accounts (Wikipedia, general species account; Reptile Database).
It is endemic to Tonaki, Tokashiki, Ie and Aka islands in the Okinawa group and feeds on insects; its narrow island range is central to reliable identification. Information absent from those species-level sources is omitted rather than inferred from relatives. Japanese occurrence follows the site's catalogue and the opened distribution accounts (Wikipedia, general species account; Reptile Database). This conservative treatment keeps unresolved parts of its natural history clearly visible to readers.
