The endemic Sri Lanka Drongo Dicrurus lophorinus nests in trees and is known to use the same host tree for several years. Here we describe a previously unknown behaviour of this species, in which it actively eliminates canopy contact between the host tree and adjacent trees, and attempts to reduce the roughness of the main trunk of the host tree to...

A new species of uropeltid snake, Rhinophis roshanpererai sp. nov., is described based on three specimens from Badulla District, Sri Lanka. The new species is distinguished from its congeners by the number of dorsal scale rows and ventral scales, a colour pattern that lacks pale stripes, and by having a very small tail shield with four or three pro...

A new species of rock dwelling gecko belonging to the genus Cnemaspis is described from Sri Lanka based on a suite of morphological features. The species is the largest of its genus described from Sri Lanka so far (snout-vent length 52-54 mm) and is the second largest of the Western Ghats-Sri Lanka Biodiversity Hotspot. It may be diagnosed in detai...

Pseudophilautus hypomelas (Günther, 1876), was previously known from the type collection of 14 specimens deposited in the Natural History Museum, London. There has been no record of this species since the original description by Günther in 1876, and subsequently this species was considered extinct. In recent explorations however, the species has be...

Eight new species of Pseudophilautus (Pseudophilautus bambaradeniyai, P. dayawansai, P. jagathgunawardanai, P. karunarathnai, P. newtonjayawardanei, P. puranappu, P. samarakoon, and P. sirilwijesundarai) were discovered as a result of a survey carried out to study the herpetofaunal diversity with the changes in elevation in the Sripada World Herita...

Pseudophilautus stellatus (Kelaart 1853) has been rediscovered from the Peak Wilderness, Central Hills of Sri Lanka. The species, till now known only from its lost holotype, was the first shrub frog described from Sri Lanka, and had not been reported since then. It was thought to have become extinct for nearly 157 years, being the amphibian species...
