Article Synopsis
  • * This study utilizes historical museum specimens and modern genomic techniques to create a nearly complete phylogeny of Uropeltidae, confirming the grouping of genera and suggesting that Sri Lankan uropeltids share a single ancestral origin from India.
  • * The research indicates that the diversity of uropeltid species may be significantly underestimated and emphasizes the importance of integrating museum collections with molecular genetics to better understand the evolution and classification of lesser-known species.

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).

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.
