Amphibians from Sabah I. Systematic and Natural History Notes

Abstract

Thirty-two species, including two questionable and three unidentified forms, of anuran amphibians from Sabah, Northern Borneo, are reported with special references to morphological variation and natural history. Twenty of the species were collected from Kinabalu regions and the others from various localities in the surrounding lowlands. Tadpole of Megophrys baluensis and unknown tadpole of Ansonia are described; variation in Rana kuhli is analysed and striped form is newly reported from Borneo; Rana rugulosa is first recorded from Sabah; distribution of Kaloula pulchra pulchra is confirmed; Rana kenepaiensis is first recorded from eastern Sabah and differentiated as a distinct species from R. paramacrodon; two probable new forms of Amolops are compared with known Bornean relatives; distribution of Polypedates leucomystax leucomystax in eastern Sahah is a significant range extension.
