Geographic range

Gehyra species have a wide geographic range, covering most of the Oceania and Melanesian Islands as far north as the Ryukyu Islands and Thailand.

Description

Dtellas are moderately sized geckos that resembles house geckos. Gehyra species have toepads and powerful claws. Like some other geckos they also have a tendency to drop strips of skin if handled carelessly. Similar to house geckos, dtellas are able to communicate with clicks or chirps, although their chirp is often quieter than that of house geckos.
