Abstract
Advertisement call structures of ten frog species, six ranids and four rhacophorids, from southwestern India were analyzed. Rana temporalis, Limnonectes limnocharis, Indirana semipalmata, Nyctibatrachus major, and Philautus cf. bombayensis had simple calls consisting either of a single note or of a series of similar notes. Limnonectes cf. keralensis and P. cf. travancoricus had a relatively long call with a well-differentiated first note, and L. syhadrensis, P. leucorhinus, and Rhacophorus malabaricus had complex call structures with a variety of call types. Several ecological notes associated with breeding, and some taxonomic problems are presented.
