Abstract

A new small-sized species of dicroglossid frog from West Bengal is described as Minervarya chilapata sp. nov. and compared to Minervarya sahyadris. It differs from all Fejervarya species by its smaller size, by the presence of a distinct white band on upper lip and by the presence of a rictal gland. The new species is separable from its congener in showing a more pointed snout, smaller tympanum and more developed webbing. Its advertisement call is described and compared to that of M. sahyadris. Generic allocation is discussed. In the Fejervarya lineage, a trend towards small-sized species may exist. The species allocated to Minervarya show an important morphological shift, presumably reflecting occupation of a different adaptive niche which might indicate generic distinctiveness.
