Rafetus is a genus of highly endangered softshell turtles in the family Trionychidae. It is a genus of large turtles which are found in freshwater habitats in Eurasia.

Species

According to most taxonomists, the genus Rafetus contains the following two extant species.

Rafetus euphraticus (Daudin, 1801) – Euphrates softshell turtle
Rafetus swinhoei (Gray, 1873) – Yangtze giant softshell turtle

A possible third species, Rafetus leloii Hà, 2000 (synonym R. vietnamensis Le et al., 2010), known commonly as the Hoan Kiem turtle, has been proposed as a species. It is considered a junior synonym of Rafetus swinhoei by most authorities,^[2] but some Vietnamese scientists insist the two forms are not identical. The last known individual at Hoan Kiem Lake was found dead on 19 January 2016.

An extinct species R. bohemicus Liebus, 1930 from the Burdigalian age (Early Miocene) about 17.5 million years ago lived in what is today the Czech Republic.^[1]
