The recent issue (June 25, 2010) of Journal Zootaxa reports the discovery of a new miniature species of sisorid catfish in Mizoram. This new finding is published by Dr Heok Hee Ng, Raffles Museum of Biodiversity Research, Singapore and Dr Lalramliana Assistant Professor, Department of Zoology, Pachhunga University College, Mizoram.
The new species has been named Pseudolaguvia virgulata. It was discovered by Dr. Lalramliana, during recent ichthyological* surveys of the Barak River drainage in Mizoram.
Members of the sisorid genus Pseudolaguvia are small catfishes found in rivers draining the sub-Himalayan region and Myanmar. They superficially resemble miniature species of Glyptothorax in overall morphology and in having a thoracic adhesive apparatus with a median depression, but can be distinguished in having prominent postcoracoid processes. The new species can be distinguished from congeners in having a brown body with two or three narrow, pale longitudinal stripes and a pale Y-shaped marking on the dorsal surface of the head.
Pseudolaguvia virgulata was collected from clear, shallow, moderately flowing streams with a predominantly sandy bottom. It is known from the Barak River drainage, which forms the headwaters of the Surma-Meghna river system, one of the three rivers that form the Ganges Delta. Source: http://www.practicalfishing.co.uk
Discovery of new species is an important aid to conservation efforts.
*Ichthyology is the study of the biology of fishes in all its ramifications, including but not confined to the sub-disciplines of form, function, and development; taxonomy, systematics, and biodiversity; migration, geographic distribution, and zoogeography; behavior and ecology; habitat loss, commercial exploitation, and conservation.
