Sri Lanka Short-horned Shrub Frog

The Sri Lanka short-horned shrub frog is endemic to south-western Sri Lanka, known from the Kanneliya-Dediyagala-Nakiyadeniya, Kitulgala and Kottawa Forest Reserves and Sinharaja. Its name singu is Sinhalese for horn, for the horn-like tubercle on each upper eyelid. Four males measured 16.1 to 16.6 mm from snout to vent. It is brown with a W-shaped mark on the back, a blackish-brown eardrum region, yellow lower flanks and three dark bars on the limbs (Wikipedia, general species account).

It occurs in lowland and mid-elevation rainforest at 60 to 513 m, and males have been found perched 0.5 to 1.5 m above the ground. Nationally Endangered (Sri Lanka National Red List 2012).
