Family : GEKKONIDAE
Species : Cyrtodactylus quadrivirgatus
Size (snout to vent) : male 69 mm, female 75 mm
Size (total length) : ~ 150 mm
This attractive gecko
inhabits lowland primary or tall secondary rainforest, freshwater swamp
forest and lower montane forest up to at least 1100 metres. It is generally
found clinging to low vegetation, and only occasionally on boulders or rock
outcrops.
It has slender digits
which lack expanded pads : the fingers and toes are well adapted for
gripping on fissured tree bark or other rough surfaces. The reddish-brown
eyes have vertical pupils. These are both distinguishing feature of
Cyrtodactylus geckos.
The body colour is medium brown, pale cream or pale grey, patterned with
four buff or dark brown lateral stripes : these may be semi-continuous or
completely broken into irregular blotches. The species is sometimes
called 'Four-striped Bent-toed Gecko'.
The tail is patterned with dark and light bands of roughly equal thickness.
The dorsal colour is pale.
The species occurs in Southern Thailand, Peninsular Malaysia and
Singapore. It is also listed as occurring in north Sumatra and north-western
Borneo.

from Fraser's Hill, Peninsular Malaysia (elevation 1000 metres), found
clinging to vegetation 0.5 metres above the ground. This specimen has well
developed dorsal superciliary scales (the yellow scales above the eye which
give the appearance of eyelashes).

1000 metres), clinging to plant roots exposed in a roadside embankment.
