Existing records indicate the presence of 64 species of amphibians in the Northeast India but this figure again could be a gross underestimate as they are a poorly studied group in Northeast India. A survey of amphibians conducted in the State of Nagaland from 1998 to 2002 has resulted in 19 species as new records for the State and 5 species (Megophrys wuliangshanensis, M. glandulosa, Amolops viridimaculatus, Rana humeralis and Rhacophorus gongshanensis) as new records for India. Only four species of caecilians, Ichthyophis garoensis, Ichthyophis hussaini, Ichthyophis sikkimensis and Gegeneophis fulleri are known from Northeast India. The Himalayan Newt (Tylototriton verrucosus) deserves a special mention, as it is the only species of Salamander known from India, occurring in Manipur, Khasi Hills and Sikkim. Hitherto, they were little affected by man, but use of the pesticides in paddy cultivation is posing a threat to the species.
