Plestiodon iheyaesilvae
Rare visitor: recorded only occasionally in this country
Plestiodon iheyaesilvae (Plestiodon iheyaesilvae) is a skink described in 2025 with five longitudinal pale lines and vivid juvenile colour, distinguished from relatives through detailed scale counts. 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). Field identification should therefore remain cautious wherever photographs or diagnostic measurements are unavailable.
It is endemic to forest on Iheyajima, with a type locality on Mount Koshidake; its name combines the island with the Latin word for forest. 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.
