A New Species of Pelophryne from Malay Peninsula (Anura, Bufonidae)

抄録

A small, semi-arboreal toad of the genus Pelophryne from Peninsular Malaysia has been treated as P. brevipes or P. signata. The peninsular toad and Bornean P. signata are very similar to each other morphologically, although slightly different in relative forelimb length, dorsal coloration, and tuberculation. However, in partial mtDNA sequence, the peninsular toad is substantially distinct from P. signata from Borneo and P. brevipes from the Philippines, although it is close to a congener from Sumatra. Thus, the peninsular toad is described as a new species based on specimens from Genting Highlands, state of Pahang, central Peninsular Malaysia. Of the two morphotypes recognized in the genus, the new species belongs to the one with the tips of the fingers expanded into truncate discs, in which the new species is the smallest in body size. The new species also occurs in Singapore and possibly in Sumatra.
