. Current herpetology. Reptiles; Herpetology. 22 Current Herpetol. 22(1) 2003 shade; limbs also brown with darker brown barring/blotches extending onto fingers and toes; tympanum entirely black; an uninter- rupted white streak from posterior margin of tympanum to just below eye; iris yellowish in dorsal third, reddish brown in ventral two thirds; throat and chest heavily mottled with dark brown, often with a white dividing line from chin towards sternum; belly and under- side of femur with reduced pigmentation. In preservative, a slight fading of the original colour occurs. Sexual dimorphism Males a little smaller than females, SVL of males to mm, females to mm. Males possess distinctly bulbous humeral glands, nearer to axilla than elbow; paired subgular vocal sacs; finely granular, unpigmented nuptial pads on first finger arranged in two separate groups, one opposite the subarticular tubercle and the other immediately adjacent to the inner metacarpal tubercle. Females with unpigmented ova. A gravid female from Singapore (ZRC. ) aborted her ova (ZRC. , ca. 400 counted) in captivity and the ova had a diame- ter of mm. Natural history Predominantly inhabitant of lowland fresh- water and peat swamp forests. Males call from among or atop leaf litter of forest floor, or perched on low vegetation up to one metre above ground. Call of male consists of an initially ascending series of high-pitched "yip- yip-yip" accelerating towards the end. Rana laterimaculata is syntopic with R. baramica in some parts of its range, and may be found with other Sundaic lowland swamp forest anurans, such as Bufo quadriporcatus, Lepto- brachium nigrops, Limnonectes paramacro- don, Phrynoglossus laevis, Rana glandulosa, Microhyla borneensis, or Rhacophorus appen- diculatus. Neither in situ nor ex situ amplexus has been observed. Its diagnostic larval iden- tity remains as yet unknown. Geographic distribution Apart from the type locality, Sadong, Sarawak,
