Taxonomy of Sri Lankan Pigmy Shrews

by on Friday, February 17th, 2012

The taxonomy of the pigmy shrews Suncus fellowesgordoni and S. etruscus is unclear and their phylogenetic relationships are unknown. Using molecular and morphological data, we confirm the species status of S. fellowesgordoni as being distinct from S. etruscus, its probable sister species. Suncus fellowesgordoni is genetically distant from S. etruscus populations in Sri Lanka, India, and Europe with a percent pairwise uncorrected genetic distance of 7.9–8.2% and 9.2–9.3% for cytochrome-b (mitochondrial DNA), respectively. The genetic distance between S. fellowesgordoni and S. etruscus of Sri Lanka and India for Rag 1 (nuclear DNA, exon) is 1.3–1.7%. The two species are also morphologically distinct by S. fellowesgordoni being larger in all dimensions, darker in hue and having two denticulations on the lower incisors.

Crocidura hikmiya, an endemic shrew from Sinharaja World Heritage Site

by on Wednesday, August 8th, 2007

A new endemic species of shrew, Crocidura hikmiya (Sinharaja Shrew) was recently described by us using molecular and morphological data, from the Sinharaja and Rakwana mountains of Sri Lanka. Its closest sister species is the Sri Lankan Long-tailed Shrew, another Sri Lankan crocidurine shrew that is restricted to the high-elevation habitats of the Central Highlands. C. hikmiya has a shorter tail than the Sri Lankan Long-tailed Shrew; most of the other characteristics that distinguish the two species are osteological in nature. Suyama led this research, with Madhava, Kelum, Rohan and Chris contributing.
