Lamprops pumilio Zimmer, 1937 Lamprops pumilio Zimmer, 1937: 41, figs 5–7.— Lomakina, 1958a: 89–90, fig. 37. Type material. Deposition unknown. Sea of Okhotsk, 59°32’N, 150°40’E. Not seen. Diagnosis . Carapace without lateral ridges, antennal notch absent, pseudorostrum pointed, eyelobe small. Telson 0.9 length of uropod peduncles, 0 pairs lateral setae, 5 terminal setae. Uropod peduncle without medial setae. Adult male antennal flagellum reaches to end of pereon. Depth . 20–25 m. Distribution . Okhotsk Sea, 59°32’N, 150°40’ E, and Kurile Islands. Remarks . The most similar species is Lamprops korroensis however, L. korroensis is found in brackish and fresh water on the Kamschatka Peninsula, and L. pumilio is a marine species. In addition, the telson in L. korroensis is less than 0.5 the uropod peduncle length, while in L. pumilio the telson is more than 0.5 the uropod peduncle length. Lamprops pumilio has no antennal notch, the anterolateral corner is entire, the pseudorostral lobes meet and extend a considerable way anterior of the eyelobe, and the telson terminal setae increase in length from the lateral to the midline, with the central seta the longest. In comparison, Alamprops affinis has the pseudorostrum extending barely anterior of the eyelobe, and the telson terminal setae are all equal in length. In A. carinatus the carapace has antennal notch. In A. obfuscatus the telson terminal setae have the outermost pair long, the next pair short, and the central seta longest. In A. serratus , the antennal notch is present, and the anterolateral corner is strongly serrate.
