Neobirsteiniamysis is a mysid crustacean genus of the subfamily Boreomysinae of the family Mysidae. Some of the largest mysids. Exclusively deep water. Cosmopolitan. 2 species.[1][2]

Description

The eyes are lacking cornea, concave laterally, with the microfibrous microstructures on the concave surface. The telson lateral margins are as wide as or wider than the anterion part of the telson. The statocyst is poorly developed.[1][3]

Taxonomy

Type species of the genus is Petalophthalmus inermis Willemoes-Suhm, 1874. The name comes from the neo- (Greek new) and Birsteiniamysis (the unavailable genus-name, replaced by Neobirsteiniamysis).[1][4]

Classification

Includes 2 species:

Neobirsteiniamysis inermis (Willemoes-Suhm, 1874)
Neobirsteiniamysis caeca (Birstein et Tchindonova, 1958)

Habitat

Neobirsteiniamysis is bathyal-abyssal genus, and thus combines exclusively deep-water oceanic mysids. Depth range 700-7200 m.[3]
