Description
Size: Length 1.80-2.40 mm (female), 1.92-2.25 mm (male).

Female: Prosome has a very characteristic shape, being very broad at the midpoint. The anterior metasome segment is produced into points which extend close to the urosome, reaching half way down the genital segment. Urosome of 4 segments. The genital segment has a downward pointing projection when viewed from the side. Setae on the swimming legs and furca are typically very feathery. The setae on the furca are of similar length.
Male: Similar to female but posterior metasome segment not produced. Urosome 5-segmented. Right foot uniramous with 2-segmented exopodite with a short terminal segment; left foot biramous, the exopodite with 3 segments, the simple endopodite with 1 segment.
