Black-eyed Bent-toed Gecko

Cyrtodactylus nigriocularis


Cyrtodactylus nigriocularis is a member of the gecko family Gekkonidae which diverged from other reptile groups 65 million years ago; about the time dinosaurs went extinct!

C. nigriocularis is known from just one area Ma Thien Lanh Valley with an estimated area of occupancy of less than 10km².

Little is known about the population trends of this species, field trips to this area suggest that the species is becoming more difficult to find.

The main threat to C. nigriocularis is habitat disturbance due to ongoing road construction where debris is known to have washed into the streams this species lives near. Additional threats come from an increase in the number of people living in the area, tourism and quarrying on the mountain.

C. nigriocularis is not known to be found in any protected areas and conservation on the few known caves this species inhabits is needed.
