Acoustic and Karyotypic Evidence for Specific Separation of Polypedates megacephalus from P. leucomystax

Abstract
The Taiwanese population of Polypedates leucomystax megacephalus is distinct from the Bornean population of P. l. leucomystax in adult morphology, mating call, and karyotype. Clear differences in the latter two characteristics suggest the presence of a high degree of genetic differentiation between the two populations. The Taiwanese population is therefore regarded as a full species, P. megacephalus Hallowell, 1860. Populations from continental China require further taxonomic investigation.
