Hemilamprops assimilis Sars, 1883: 11, 55, pl. 1 figs 23–24.—Sars, 1899: 23, pl. 15.

Type material. Deposition unknown. Vardø, Finmark, N.E. Norway. Not seen .

Diagnosis. Carapace without lateral ridges, without setae, dorsal crest entire. Telson subequal to uropod peduncles, with 1 pair long lateral setae, 6 terminal setae, outer pair longest. Uropod exopod article 1 0.6 length of article 2. Adult male antenna extending to posterior border of pleonite 5.

Depth. 55–3000 m.

Distribution. Boreal Atlantic.

Remarks. There are only two species of Hemilamprops with more than 5 terminal setae on the telson, H. assimilis and H. roseus . The two species can be distinguished easily by the eyelobe and the lateral setation on the telson. In H. assimilis the eyelobe is very small and has no lenses, and the telson has only one pair of lateral setae, while in H. roseus the eyelobe is larger, possesses several lenses, and the telson has at least two pairs of lateral setae.
