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 details of both scalation (ventrals186-207; mid-subcaudals large; absence of precloacal pores; 15 femoral pores on each side; 22-23 and 23-25 subdigital lamellae on finger IV and on toe IV, respectively; smooth scales on tail dorsum) and colouration (five prominent trilobate shaped cream markings pointing towards head and extending from neck to vent).The species is found in a unique habitat in the Rammalakanda Forest, where it is threatened by deforestation Copyright © 2014 Magnolia Press.

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 "lost" for the longest amount of time. Here we designate a neotype from the material collected at what we consider its type locality, having considered characters of the lost holotype and provide a complete description. We have conducted a molecular phy-logenetic analysis, on which basis the species is well differentiated from all other Pseudophilautus sequenced so far, and placed in a clade together with P. femoralis, P. frankenbergi, P. mooreorum, and P. poppiae.

The Sri Lankan uropeltid (shieldtail) snake Rhinophis dorsimaculatus Deraniyagala, 1941 was described originally from two specimens that were subsequently lost. The small amount of previously published data and lack of published colour photographs made this one of South Asia's most poorly known snake species, and this resulted in at least one instance of taxonomic misidentification. An additional 10 specimens from a historical collection from the vicinity of the type locality recently came to light. This material is reviewed and documented and the species recharacterized. An additional locality for the species is reported. The newly reported material helps to corroborate the taxonomic validity and distinctiveness of Rhinophis dorsimaculatus. The species is readily distinguished from congeners by having 227 or more ventral scales; a large, dorsally carinate rostral shield; posterior margins of paired anals that are largely separated by the posteriormost ventral scale; and a distinctive colour pattern with bilaterally asymmetrical dark blotches within a broad, pale middorsal stripe and regularly punctate flanks.

A new species of Cnemaspis, Cnemaspis rajakarunai sp. nov. is described and is the fourth rock dwelling species belonging to the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by the following combination of characters: adult snout vent length 36 40 mm; precloacal pores absent, large femoero-precloacal scales 22; femoral pores 7 8, enlarged femoral scales 6; ventral scales 146 186; supralabials (to midorbital position) 7; supralabials (to angle of jaws) 9; total lamellae on finger IV 19 22, shape of the basal lamellae on toe IV elliptical; and its unique colour pattern. The new species is recorded from Salgala Forest an unprotected lowland rain forest. © 2016 Magnolia Press.

A new species of Dendrelaphis, Dendrelaphis sinharajensis sp. nov. is described, the sixth species of the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by its colour pattern and scalation. The species is a canopy-dweller known only from the Sinharaja World Heritage Site and its vicinity, in the lowland wet zone of Sri Lanka. © 2016 Magnolia Press.

Adenomus kandianus Günther (1872) was previously known only from two specimens both deposited in the British Museum, the holotype BMNH1947.2.20.63, and the syntype of A. kelaarti BMNH1947.2.20.62. The only record of A. kandianus since the initial description in 1872 was by Ferguson in 1876, who mentions two specimens resembling Bufo kandianus in his collection, making A. kandianus the world's rarest toad. The species had not been reported since, and was considered extinct. Here we report on its rediscovery. copyright © 2012. Magnolia press.
