The taxonomic status of the large-sized Fejervarya frogs of the Andaman and Nicobar Islands was assessed based on integrative analysis of molecular, morphological and acoustic data. Our results identify the population from the Andaman Islands as Fejervarya moodiei, and that from the Nicobar Islands as F. limnocharis. Representative specimens collected during this study are described along with observations on their natural history. The distribution of F. moodiei within the Andaman Islands and F. limnocharis in the Nicobar Islands recorded during this study are mapped, suggesting that these species are fairly widespread.
