摘要

The suggestion that the fauna of the Western Ghats (a recognized biodiversity hot spot) includes many species of amphibians that await formal scientific description, has proven controversial. The controversy largely revolves around whether these undescribed taxa are only now being recognized because of changes in taxonomic philosophy and methodology, or simply because of increased work that is uncovering biological reality. A recent article in this journal used a plot of cumulative species descriptions over time to support the latter explanation, by showing that the species discovery curve has yet to reach an asymptote. It is noteworthy that the debate thus far, while cast in terms of amphibian diversity, has focused almost exclusively on frogs. Wethink it useful to broaden the empirical basis for the debate by considering also what is known of the taxonomy and biodiversity of the other order of amphibians that occur in the Western Ghats, the caecilians (Gymnophiona).
