The notodelphyid genus Doroixys Kerschner, 1879 (Crustacea: Copepoda: Cyclopoida), with the description of a new species from the Russian far east.
Doroixys simplex n. sp. is described from material collected from a tunicate of the genus Ciona, collected on the North Pacific coast of Russia. This is the fourth species of the genus and the first for which the male has been found. The new species differs from congeners most noticeably in the absence of posterolateral processes from the rear margin of the dorsal cephalic shield. A key to species is provided.
