Gehyra is a genus of geckos in the family Gekkonidae. They are known as web-toed geckos or dtellas, and most species within the genus bear close resemblance to geckos from the genus Hemidactylus.

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 resemble 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.

Lizard genera
Taxa named by John Edward Gray
네발톱도마뱀붙이속(Gehyra), 일명 웹토 게코(web-toed geckos), 디텔라(dtellas)는 도마뱀붙이과에 속한 도마뱀붙이류의 일속이며, 집도마뱀붙이류를 닮아서 아시아의 어떤 지역에서는 흔히 오인받는다.

분포 
네발톱도마뱀붙이속은 분포범위가 넓다. 오세아니아와 멜라네시아의 대부분의 영역을 차지하며, 북쪽으로는 태국과 류큐 열도에 이른다.

형태 
네발톱도마뱀붙이속은 집도마뱀붙이속을 닮은 중형 도마뱀붙이류이다. 발가락에는 빨판과 튼튼한 발톱이 있다. 다른 몇몇 도마뱀붙이류처럼 부주의하게 핸들링하면 찢어진 피부를 떨구는 경향이 있다. 집도마뱀붙이류와 비슷하게 찍찍 짹짹 대며 의사소통을 할 수 있지만, 찍찍대는 소리는 대개 집도마뱀붙이류보다 작다.
