 A new nightfrog, Nyctibatrachus minimus sp. nov.(Anura: Nyctibatrachidae) is described from Kurichiyarmala in the Western Ghats, India. Its most distinctive feature is the small adult snout-vent length,averaging only 12.3 mm in adult males (N = 15), makingit the smallest known frog from India. Analyses of afragment of the mitochondrial NADH dehydrogenase1 gene indicate a minimum divergence of 22% withknown small-sized congeners. Miniaturization in Nyctibatrachus sp. seems to be associated with absence of webbing on toes and fingers, which may have resultedfrom evolutionary specialization to life in terrestrial habitats.

Keywords: NADH dehydrogenase 1, Nyctibatrachus minimus sp. nov., smallest Indian frog, Western Ghats.
