Hansen, 1905

Description
Antennula (a1) with the first article extending forwards, the second article in a right angle to the first. Antennules scarcely reaching anterior angle of the pereion; third peduncular article scarcely longer than the second; antennular flagellum thick in male, slender in female. Antennal peduncle (a2) with four distinct articles.
Maxillipede without coupling hooks on the inner border.
Coxal plates of pereion somites 6-7 with sharp posterior angles but not produced into a process. Pleon somite 5 not markedly reduced, with the lateral borders contributing to the body outline.
Pleopod 1 with both rami thinly chitinised and fringed with setae. The peduncle of the uropod is not markedly reduced backwards alongside the inner border of the endopod; the articulation between the peduncle and the endopod is short. Pleotelson similar to Eurydice pulchra: the posterior border is fairly broadly rounded, with two small spines at each corner along the fairly long plumose setae.

Size
Males recognisable at just over 2 mm body length, ranging to about 5 mm; females 2-6 mm.

Colour
Pale, with black chromatophores restricted to the dorsal body surface; abdomen yellowish.
