Family HALOCYPRIDIDAE Dana, 1853
Introduction
A discussion on the origin of Halocyprididae is presented in Kornicker et al. (2010), including the possibility that the family evolved from cave-dwelling ancestors.
Diagnosis
Valves very weakly calcified, usually elongate, rather rectangular, some rather ovate; anterior margin usually with conspicuous rostrum and incisure or at least a slight indentation; dorsal margin often quite straight, posterodorsal corner often with acute or spine-like glandular process; posterior and anteroventral margins convex. Non-radial muscle scar pattern. Antennula with 3–8 articulated segments, usually bent downwards distally, occasionally also bent between first and second segments; first segment without setae; some with distal filament pad. Antennal endopod with 2 (female) or 3 (male) segments. Sixth limb sometimes sexually dimorphic, short with a terminal claw in female, long with flexible terminal setae in male; exopod reduced or represented only by one seta. Male copulatory appendage with 1–2 parts. Furca with all claws articulated at base. Bellonci organ bifurcate or not, sometimes absent.
