The dorsal surface of the
Black-bearded Gliding Lizard is generally greenish in colour. The male
(left) possesses a long black gular flag, whilst the female has a smaller
gular flag which is reddish grey to grey. The
patagium is brownish-black covered with yellow spots.
Its body is long and slender, and the tail comprises around 60% of total
length.
Its diet comprises mainly ants,
termites and other small invertebrates. The female lays just two eggs in
each clutch.
This small to medium species is common in lowland primary and secondary
rainforests, and its range encompasses Southern Thailand, Peninsular
Malaysia, and Sumatra, Borneo and other Indonesian Islands. In Singapore it
is restricted to the primary forests of Bukit Timah and the mainly secondary
forests of the Central Catchment Area.
