Abstract The genus Metamysidopsis W. M. Tattersall is currently represented by two species in the eastern Pacific: M. elongata (Holmes, 1910) in California, U.S.A., and M. pacifica (Zimmer, 1918) in Peru and Panama. The distribution and some morphological details of both species are presented and discussed and a new species is described from the southern Gulf of California, western Mexico. Commonly used diagnostic characters for the species of Metamysidopsis are analysed based on data available in the literature. A diagnosis is provided for the three species occurring in the eastern Pacific and a key to the 10 currently known species of the genus is provided.
