Brazilian Bent-toed Gecko, Gymnodactylus geckoides Spix


Bent-toed Gecko, Gymnodactylus geckoides is listed here on the basis of a single museum specimen. It is not likely part of the current fauna. If this genus is present on Trinidad, it can be identified by the presence of free fingers that are not expanded; the fingers have wide, undivided sub-digital lamellae; the distal phalanges are elevated above the basal ones; the nail or claw is placed between two scales with the ventral scale indented; straight, vertical pupils and dorsal scales are a mixture of granules and tubercles. This lizard is otherwise known from Brazil; its presence on Trinidad is problematic.
The only known specimen (FMNH 177679) of Gymnodactylus gekkoides supposedly collected in Trinidad's Arima Valley in 1962 by Edward Taylor.
