Family : MEGOPHRYIDAE
Species : Leptolalax sp.
Size (snout to vent) :
This specimen approx 2.5 cm
There are more than 20
species comprising the genus Leptolalax : most are frogs of primary
forest habitats. Typically they inhabit the forest floor, but they may also
be found perching on low twigs and small branches overhanging forest streams
at a height of around a metre or so.
The frog shown here illustrates the fairly typical morphology of the genus :
small size, large dark eyes, slender forelimbs, long hindlimbs, fingers and
toes mainly unwebbed and a long third toe.
Many species of the genus are hard to distinguish in the field : some may
only be properly identified on the basis of their call.
The specimen illustrated
here was found clinging to the branch of a shrub at the base of a
small waterfall at Fraser's Hill, Peninsular Malaysia. It is tentatively
identified as Leptolalax heteropus (Variable Litter Frog).
Frogs of the genus
Leptolalax range from southern China and Myanmar through Thailand and
Vietnam to Peninsular Malaysia. They are absent from Singapore.
