Ansonia longidigita (common names: long-fingered slender toad, long-fingered stream toad) is a species of toad in the family Bufonidae.[1][3][4] It is endemic to northern and western Borneo in Sabah and Sarawak (Malaysia) and in Brunei.[3]

Description

The specific name longidigita means "long-fingered"[4] and refers to the long and slender fingers of the species.[2] Males measure 40–50 mm (1.6–2.0 in) whereas females can grow to 70 mm (2.8 in) in snout–vent length.[4] It has a slender habitus. The tympanum is distinct. Dorsal skin has numerous small, round warts.[2]

Tadpoles are very small, commonly less than 15 mm (0.59 in) in length. They have dark blotches on cream background colour.[4]

Habitat and conservation

Ansonia longidigita is a common toad inhabiting mid-elevation hills.[4] Adults live on the forest floor or low in the vegetation.[1] They breed in small, clear brooks and streams with rocky bottom.[1][4] Males call from the stream boulders or from vegetation by the stream.[4]

The species is threatened by habitat loss caused by logging, and the siltation of streams that logging leads to.[1]
