Cyrtodactylus pubisulcus Inger’s Bent-toed Gecko
Some other names for this species:
Inger’s Bow-fingered Gecko
Santubong Peninsula, Sarawak, MalaysiaJanuary 29, 2017
Inger’s Bent-toed Gecko (Cyrtodactylus pubisulcus)
If I had seen this gecko in Peninsular Malaysia, I would have been confident that it was Cyrtodactylus quadrivirgatus. That species is found in Borneo as well as in Peninsular Malaysia, but as far as I have been able to discover the ones that look like this on the Santubong Peninsula are C. pubisulcus.

My Travelogues and Trip Lists page includes a complete list of the herps I saw in the wild on this trip to Malaysia, as well as a travelogue of the trip.

Inger’s Bent-toed Gecko (Cyrtodactylus pubisulcus) Inger’s Bent-toed Gecko (Cyrtodactylus pubisulcus)
These two have such different overall appearance that I wouldn't be surprised if they turned out to be different species, but as far as I have been able to tell they are just "dark phase" and "light phase" C. pubisulcus.
