ABSTRACT

Taxonomic status of the Andamanese subspecies of Kaloula baleata i.e., Kaloula baleata ghoshi is re-evaluated based on a comparative analysis of morphological data from members of this species complex from different parts of Southeast Asia. The Andamanese population is shown to be a morphologically distinct, allopatric species deserving specific recognition similar to the recently recognized and named members of this species complex from other parts of Southeast Asia. Thus, the population in the Andaman Islands hitherto considered being a subspecies of Kaloula baleata is elevated to species status in the combination Kaloula ghoshi. Descriptive notes on morphology, distribution and natural history of this poorly known taxon are presented herein for the first time based on extensive field-surveys conducted in the Andaman Islands.

KEY WORDS: Kaloula, Andaman Islands, species complex, subspecies, elevation, allopatry, Java
