Pseudolamprops abyssi ( Gamô, 1989a) n. comb.

Hemilamprops (?) abyssi Gamô 1989a: 29–32 , fig. 10; 1989b, 100–101.

Type material. Holotype: NSMT-Cr. 9645, subadult female. 38°33.9’– 38°35.5’N, 145°15.7’– 145°10.1’E. Not seen.

Diagnosis. Carapace with spines on dorsal surface restricted to pair of lines of spines on anterior dorsal surface, single median line on frontal lobe, and 1 pair of spines on dorsally anterior of eyelobe. Maxilliped 1dactylus subequal to propodus.

Depth. 5349–5368 m.

Distribution. Japan Trench, 38°33.9’N, 145°15.7’E.

Remarks. This species has only been collected once, by Gamô (1989a). This species fits the definition of Pseudolamprops in that it has a truncate mandible. Pseudolamprops abyssi can be distinguished from P. spinifer by the pattern of spines on the carapace. In P. spinifer there are many spines dorsally on the carapace, but they are not organized into lines. In P. abyssi there are fewer spines, they are organized into a pair of dorsal lines on the posterior half of the carapace, a single medial line dorsally on the frontal lobe, comparable to the dorsal crest found in many Hemilamprops , and a pair of spines on the pseudorostral lobes anterior of the eyelobe.
