A new wide-headed Fanged Frog of the Limnonectes kuhlii group (Anura: Dicroglossidae) from western Borneo with a redescription of Rana conspicillata Günther, 1872



We re-examined the type series of Rana conspicillata Günther, 1872 from Matang in western Sarawak, Borneo and found it to consist of specimens of three distinct species that can be separated by qualitative morphological characters and morphometrics. We re-allocate one paralectotype to Limnonectes hikidai and another to a large-sized species from western Borneo that we describe as new. The new species is morphologically distinguished from all described species of the L. kuhlii group from the Sunda region by body size, extent of toe webbing, head size and odontoid shape. It differs genetically from all described species for which genetic information is available. In order to facilitate the further taxonomic revision of the L. kuhlii group on Borneo, we provide a detailed morphological redescription of the holotype of Rana conspicillata.
