UNVEILING MISIDENTIFICATION OF FORMERLY REPORTED Microhyla fissipes BOULENGER, 1884 (ANURA: MICROHYLIDAE) WITH NOTES ON TWO Microhyla SPECIES FROM SUMATRA

Sumatra is widely recognized as a land bridge for the dispersal of amphibians between mainland Asia and the rest of the Indonesian Archipelago. Currently, six species of Microhyla are recognized in Sumatra: M. gadjahmadai, M. nakkavaram, M. palmipes, M. sundaica, M. superciliaris, and M. sriwijaya. Pradana et al. (2017) identified some Microhyla specimens from Sumatra as M. fissipes using molecular analysis (partial sequence of 16S mtDNA). Meanwhile, Yuan et al. (2016) restricted the distribution of M. fissipes to the northeast of the Red River Valley and Taiwan. In this study, we have revised the identification of ‘Microhyla sp. aff. fissipes’ Sumatra sensu Pradana et al. (2017) to M. mukhlesuri, based on both molecular and morphological analyses. Additionally, we report the first site records of M. mantheyi and M. butleri from Sumatra. We reconfirm the diagnostic characters based on their original descriptions and report on the morphological variation of the Sumatran populations of these three species. © Research Center for Climate Change and Department of Biology, Faculty of Mathematics & Natural Sciences, University of Indonesia, Depok 16424, INDONESIA.
