Quasipaa shini

Quasipaa shini (common names: spiny-flanked frog, Chinese paa frog) is a species of frog in the family Dicroglossidae. It is endemic to southern central China (Guangxi, Guizhou, Hunan, and Chongqing). Its natural habitats are rivers in subtropical moist lowland forests and montane forest at elevations of 510 - 1500 m asl. It is threatened by over-collecting for human consumption and by habitat loss.

Quasipaa shini are relatively large frogs. Males grow to a snout–vent length of about 99 mm and females to 95 mm. Tadpoles are up to about 66 mm in length.

Its specific name shini ("of Shin" in Latin) honours the biology professor. The German zoologist Ernst Ahl, who named the species, also named the lizard Shinisaurus after professor Sin.
