Alamprops flavus ( Harada, 1959) n. comb.

Lamprops flava Harada, 1959: 234–237 , fig. 3.—Gamô, 1963, 15; 1967, 264.

Type material. Deposition unknown. Shimoda Bay, Japan. Not seen .

Diagnosis. Carapace without lateral ridges; eyelobe not extending to anterior border of pseudorostrum. Telson without lateral setae, 5 terminal setae, outermost pair longest, inner pair shortest. Uropod peduncle with medial setae; uropod exopod article 1 1.4 length of article 2. Male antennal flagellum extending to midline of pleonite 5.

Depth. Not determined, estimated 0–10 m (modern depth, www.ports.com), collected by light trap .

Distribution. Shimoda Bay, Izu Peninsula, Japan, 34°40.2’N, 138°57’E (location, www.ports.com)

Remarks. Alamprops flavus is most similar to A. carinatus and A. obfuscatus , but can be differentiated by the terminal setae on the telson and the setae on the uropod peduncle. In A. carinatus , the central terminal seta is the longest, while in A. flavus the outermost pair of terminal setae on the telson are the longest. In A. obfuscatus the uropod peduncle has 8 or more medial setae, while in A. flavus there are only 5 or fewer setae medially on the uropod peduncle. In addition, A. flavus is only known from Japan.
