About Ansonia minuta Inger, 1960
Ansonia minuta is a small species in the genus Ansonia. In terms of snout–vent length, males measure between 20–24 mm (0.79–0.94 in), while females can reach up to 30 mm (1.2 in). This species has a slender build and a wide, truncate snout. Its ear tympani are visible, and the feet have only rudimentary webbing. The skin on its back is tuberculate and covered in rounded warts, while the flanks and throat have finer granulation. Males of this species have a vocal sac with a longitudinal slit located on the left side of the mouth. Recorded larvae grow up to 17.2 mm (0.68 in) in length. This species is endemic to Borneo. It is found in western and central Sarawak and Sabah in Malaysia, as well as adjacent western Kalimantan (Indonesia), occurring at elevations between 200–1,000 m (660–3,280 ft) above sea level. Ansonia minuta is terrestrial, and lives in lowland rainforests. It breeds in small, rocky streams that have clear, flowing water, and larvae develop within these streams.
