male Holotype


Leptolalax kecil Matsui, Belabut, Ahmad & Yong, 2009

A new megophryid species, Leptolalax kecil, is described from the Cameron Highlands of Peninsular Malaysia on the basis of acoustic and morphological characteristics. It has an advertisement call dissimilar to that of other, congeneric species, and is the smallest of the known Leptolalax. It is similar to L. pluvialis from Vietnam in small body size, but differs from it in ventral color, and in the size and color of the pectoral gland. The distributional pattern of the new species is discussed.

Keywords: Acoustics, Leptolalax, new species, Southeast Asia, taxonomy, zoogeography


Etymology: The specific name kecil is Malay, denoting small.
