A New Species of Meristogenys (Anura: Ranidae) From Sarawak, Borneo

Zoolog Sci. 2015 Oct;32(5):474-84. doi: 10.2108/zs140289.

Abstract

A cryptic Bornean torrent frog of the genus Meristogenys, which is divergent genetically and morphologically from all known congeners, is described from mountain streams of western Sarawak, East Malaysia (Borneo). The species occurs sympatrically with the type species of the genus, M. jerboa, but apparently differs from it in adult coloration and larval morphology, such as keratodont formulae and glands in tail fins. Females of the new species possess much larger and fewer eggs than in sympatric M. jerboa, suggesting significantly different reproductive traits between these species. A key to larvae of known species of the genus is provided.

Keywords: Borneo; Meristogenys penrissenensis sp. nov.; larval morphology; mtDNA phylogeny; taxonomy.
