Genus Eusarsiella Cohen & Kornicker, 1975

Type species: Sarsiella tumida Scott, 1905 by subsequent designation in Cohen & Kornicker (1975).

Diagnosis. The most species-rich genus of the subfamily Sarsiellinae , with c-, f-, and g-bristles not claw-like on the first limb and the d-bristle present. These ostracods have an anterior incisure and the posterior infold bears a row of spinous bristles. In females, the seventh limb bears paired, terminal teeth. Each lamella of the furca with five claws; claw 1 fused to the lamella, claws 2–5 separated from lamella by suture. Claws decrease in length posteriorly along lamella. For a key to Sarsiellidae , see Kornicker (1986).
