Scutiger mammatus (known as the Tungsolo lazy toad or chest spiny cat-eyed toad) is a very common species known from southeastern Qinghai, western Sichuan, eastern Xizang and northwestern Yunnan provinces in western China, from 2,600-4,200m asl. It inhabits small to medium sized low-gradient streams, seepages and spring-fed marshes in sub-alpine and alpine areas. The surrounding habitats may include cultivated fields, forests, shrublands, grasslands and/or only sparse vegetation. It breeds in freshwater.
There are no threats known to Scutiger mammatus expect perhaps overgrazing, and a lot of protected areas are present within the range of this species. The IUCN lists it as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Taxonomic note: Zhao and Jiang (1982) and Zhao and Adler (1993) considered Scutiger ruginosus to be a separate species from S. mammatus. Fei et al. (1986) considered S. ruginosus to be a polymorphic form of S. gladulatus and S. mammatus. we consider S. ruginosus to be a synonym of S. mammatus pending further taxonomic work.

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]
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]
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]
