Scutiger mammatus (common names: Tungsolo lazy toad, chest spiny cat-eyed toad, spiny-chest cat-eyed toad) is a species of frog in the family Megophryidae. It is endemic to Western China and known from eastern Tibet, southeastern Qinghai, western Sichuan, and northwestern Yunnan.[1][2][3]

Description

[edit]

Adult males measure 62–81 mm (2.4–3.2 in) and adult females 61–78 mm (2.4–3.1 in) in snout–vent length,[3] although Jiang and colleagues report a much lower range for males, 60–72 mm (2.4–2.8 in).[4] The head is broad and depressed. The tympanum is small and hidden under skin. The toes are partially webbed.[3] Males have nuptial spines on the first and second fingers, as well as two well-developed chest glands covered by strong spines.[5] No vocal sac is present.[4]

The tadpoles are adapted to running water and have elongated, dorso-ventrally flattened bodies and long tails. They grow to a total length of 80 mm (3.1 in), of which the body makes about one third.[5]

Habitat and conservation

[edit]

Scutiger mammatus lives in small to medium-sized low-gradient streams, seepages, and spring-fed marshes in sub-alpine and alpine areas at elevations of 2,600–4,200 m (8,500–13,800 ft) above sea level. It is a very common species. Threats to it are unknown, but overgrazing is a potential threat. There are many protected areas within its range.[1]
