Alamprops multifasciatus ( Zimmer, 1937) n. comb.

Lamprops multifasciatus Zimmer, 1937: 39–42 , figs 3–4.— Lomakina 1955: 136; 1958a: 88, fig. 35; 1958b: 209.

Type material. Deposition unknown. North Sea of Japan. Not seen .

Diagnosis. Carapace with 6 or more lateral ridges; eyelobe with lenses, not extending to anterior border of pseudorostrum. Telson with 2 pairs of lateral setae, 5 terminal setae, central seta equal to outermost pair, inner pair short. Uropod peduncle with 7 medial setae; uropod exopod article 1 0.8 length of article 2. Male with long antennal flagellum.

Depth. 14–92 m.

Distribution. Sea of Japan, 51°36’N, 141°08’E; Okhotsk Sea.

Remarks. This species is similar to the Alamprops augustinensis , A. krasheninnikovi , A. longispina , A. quadriplicatus group, but can be differentiated by the greater number of ridges on the carapace. In A. multifasciatus there are six ridges, although some are partial ridges, while in the other species there are no more than four entire ridges, and one of the four ridges may be difficult to discern. The only species in Lamprops with multiple ridges is L. fasciatus with three ridges.
