Atyopsis
Sign in to saveAtyopsis 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.

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, Atyopsis spinipes and Atyopsis moluccensis. No fossil representatives are known. They are found on volcanic islands from Sri Lanka to the Samoan Islands, and as far north as Okinawa, as well as on the Asian mainland from the Malay Peninsula to India. The two species differ in the number of teeth on the underside of the rostrum, with A. spinipes having 2–6, while A. moluccensis has 7–16.
