Material examined. Wallis Islands. MUSORSTOM 7. Stn 606, 13º21.4’S, 176º08.3’W, 26 May 1992, 420– 430 m: 1 M 12.2 mm (holotype, MNHN-Ga3653), 13 M 8.2–12.9 mm, 5 ov. F 10.6–11.3 mm, 10 F 6.7–11.2 mm (MNHN-Ga3755) GoogleMaps .

Bayonnaise Bank. MUSORSTOM 7. Stn 629, 11º53.7’S, 179º32.3’W, 29 May 1992, 400– 420 m: 3 M 11.8–12.6 mm, 2 F 10.1–12.3 mm (MNHN-Ga3757).

Diagnosis. Rostrum triangular, larger than supraocular spines, with thin dorsal carina; margin between rostral and supraocular spines straight or slightly concave. Spinules on gastric and hepatic regions usually not forming groups, lacking scaly striae and with few short uniramous setae. Mesogastric region with 3 welldeveloped spines. Cardiac region with 3 or 4 well-developed spines in midline. Few and short setae along anterior branch of cervical groove. Sternal plastron with some short median striae on sternite 4, and few short lateral striae on sternites 5–7. Lateral margin of antennular segment 1 with distal slender portion about half as long as proximal inflated portion. Antennal peduncle with anterior prolongation of segment 1 spiniform; segment 2 twice longer than broad, distomesial spine spiniform, reaching end of segment 3, distolateral spine not reaching end of segment 3; segment 3 twice longer than broad. Base of P1 carpus without bundle of setae. P2 propodus about 9 times as long as wide, and 1.5 times dactylus length.

Remarks. Paramunida luminata is closely related to P. antares n. sp. from New Caledonia. However, they can be differentiated by the presence of a median row of small spines behind the rostral spine in P. antares , whereas this row is absent in P. luminata . Furthermore, the gastric and hepatic regions have numerous spines (other than mesogastric and epigastric spines) in P. antares ( Fig. 12C), whereas these spines are nearly absent in P. luminata ( Fig. 13I). The genetic divergences were 1.90% (16S rRNA) and 5.49% (ND1).
