Description

Males measure 42–62 mm (1.7–2.4 in) and females 45–67 mm (1.8–2.6 in) in snout–vent length. The dorsum is olive green, brown, or greyish-brown with numerous warts and variable patterning. The underparts are yellowish, uniform and smooth. The head is wider than long; the tympanum is hidden. The parotoid gland are present. The fingers have no webbing whereas the toes have rudimentary webbing.[3] Tadpoles are up to 53 mm (2.1 in) in length.[4]

Habitat and conservation

Scutiger sikimmensis is an alpine toad living near streams, oxbow lakes, seepages, and stream-fed marshes as well as the surrounding forest and grassland habitats.[1][3][4] Breeding takes place in streams in May–June[4] or June–August;[3] males call from under the rocks at night.[1][3] The altitudinal range differs between sources; the lower limit is about 2,500 m (8,200 ft) and the upper limit 4,600–5,000 m (15,100–16,400 ft) above sea level.[1][3]

The species is common in the Indian part of its range but rare in Tibet. Major threats are diversion of water from breeding streams for irrigation and water pollution from agrochemicals. However, it is not considered threatened overall.[1]
