Abstract
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.

Systematics:
Pelophryne ingeri sp. nov.
Pelophryne signata: Hendrickson, 1966, p. 73 (part).
Pelophryne brevipes: Grandison, 1972, p. 54 (part); Berry, 1975, p. 55 (part).
Diagnosis: The new species is placed in the genus Pelophryne by having the fingers and toes with a peculiar, fleshy web. A small Pelophryne, adult males 16–17 mm; tips of fingers expanded into truncate discs; disk of third finger slightly smaller than tympanum; tibiotarsal articulation of adpressed limb reaching to posterior corner of eye; dorsum clay brown, with a cruciform pattern outlined by darker bands; creamy band extending from below eye to groin, merging on flank with creamy abdomen with small dark spots; males with mandibular spines and nuptial pad.

Holotype: KUHE 15647, an adult male collected near a pond in Genting Highlands, State of Pahang, Malaysia (..., 850 m a.s.l.) by M. Matsui and K. Araya on 17 January 1993.
Paratype: KUHE 35585, an adult male, data same as the holotype.
Etymology: The specific name is dedicated to the late Dr. Robert F. Inger, Emeritus Curator of the Field Museum of Natural History, Chicago, for his great contributions to Southeast Asian herpetology, including taxonomy of Pelophryne.
