Sri Lanka Petite Shrub Frog

The Sri Lanka petite shrub frog is endemic to south-western Sri Lanka and known from only two places in Galle District, the Beraliya and Kanneliya Forest Reserves. Its name tanu is Sinhalese for slender. Three males measured 13.5 to 13.9 mm from snout to vent. It is pale brown with about eight dark-brown stripes on the back and a dark stripe from the snout through the eye to the flank, and white below with scattered brown pigment (Wikipedia, general species account).

It lives at forest edges in open shrub areas of the lowland wet zone at 24 to 45 m, and males have been found on shrub leaves 0.5 to 1 m up. Within its habitat it is common, and at Kanneliya it was the most common species in fern-dominated habitat. Nationally Endangered (Sri Lanka National Red List 2012).
