Atyopsis is a genus of freshwater shrimp from Southeast Asia. It was erected in 1983 by Fenner A. Chace Jr. for two species formerly treated in the genus Atya. It differs from Atya by various characters including the form of the telson (which is longest at the corners in Atyopsis but not in Atya) and the presence of a massive spur on the male third pereiopod.The genus comprises two species Atya spinipes and Atyopsis moluccensis. No fossil representatives are known.
