Alamprops donghaensis (Kim & Kim, 2015) n. comb.

Lamprops donghaensis Kim & Kim, 2015: 60–68, figs 1–5.

Type material. Holotype: NIBRIV 0000317121, adult male. Paratypes: DKU CUM 201501, 320 males. Geojin Port, South Korea, 38°26’44”N, 128°27’40”E. Not seen.

Diagnosis. Carapace without lateral ridges; eyelobe not extending to anterior border of pseudorostrum. Pereonite 2 concave dorsally. Telson without lateral setae, 5 unequal terminal setae, central seta longest. Uropod peduncle with 17–18 medial setae; uropod exopod article 1 1.7 length of article 2. Male antennal flagellum extending past telson.

Depth. Not determined, described as “shallow water”, estimated 0–10 m, collected by light trap.

Distribution. Geojin Port, Gangneung Port, Oeongchi Port, and Cheongchoho, all Gangwon-do Korea, 37– 38°N, 128°E.

Remarks. Alamprops donghaensis is most similar to A. carinatus, in having no ridges on the carapace, no lateral setae on the telson, and the central terminal seta on the telson being the longest. Alamprops donghaensis is unique in Alamprops and Lamprops in having pereonite 2 with a dorsal depression and a lateral circular depression. Kim & Kim (2015) provide an extensive discussion of discrimination of A. donghaensis from similar congeners within Lamprops sensu lato (Alamprops and Lamprops). It must be noted that the description of the species is entirely based on adult males, as all specimens were collected via light trap, and it is possible that females and juveniles will not possess the same distinguishing characteristics on pereonite 2.
