Abstract

Limnonectes hascheanus and l. Limborgi are two closely related species that are herein referred to as the limnonectes hascheanus–limborgi complex. In the past, l. Hascheanus was the only species reported to be present in peninsular malaysia. Matsui reported one of their examined specimens from janda baik as l. Limborgi. This study aimed to ascertain the status of both species in peninsular malaysia through an integrated approach, combining morphological, bioacoustic and molecular data. The results indicated that in peninsular malaysia there two different lineages of the l. Hascheanus–limborgi complex that can be separated genetically, by their male advertisement calls, as well as by external morphology. Both lineages differ by having a high genetic distance between them of 2.4–7.8% based on both mtdna 16s rrna and nudna tyrosinase genes. One lineage has a morphotype assignable to l. Hascheanus described from penang island and bears the following characteristics: slender body and light or dark–olive–brown color; toe webbing not reaching middle subarticular tubercle on the fourth toe; and the absence of enlarged odontoids in males. Populations from langkawi island; kedah, perlis, and some specimens from bukit larut, perak are genetically and bioacoustically similar to topotypic specimens of l. Hascheanus from penang island.
