( Figs. 13H, 17F)

Paramunida lophia Cabezas, Macpherson & Machordom, 2009: 478 , fig. 6 ( Solomon Islands, 135–325 m).

Material examined. Solomon Islands. SALOMON 1, Stn 1831, 10°12.1'S, 161°19.2'E, 05 October 2001, 135– 325 m:1 M 10.2 mm (holotype, MNHN-Ga6512), 2M 13 mm (paratypes, MNHN-Ga6513). SALOMON 2, Stn 2191, 08º23.8’S, 159º27.1’E, 24 October 2004, 300 m: 1 ov. F 10.2 mm (paratype, MNHN-Ga6514) . —

Diagnosis. Rostrum spiniform, larger than supraocular spines, with thin dorsal carina; margin between rostral and supraocular spines straight or slightly concave. Few spinules on gastric and hepatic regions arising from striae. Mesogastric region with 3 distinct spines. Median cardiac region with 3 or 4 well-developed spines. 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 nearly twice longer than broad with distomesial spine mucronated, clearly overreaching end of antennal peduncle, distolateral spine not reaching end of segment 3; segment 3 twice longer than broad. Base of P1 carpus without bundle of setae. P2 propodus 9.5–10 times as long as wide; 1.2–1.4 times dactylus length.

Remarks. This species is closely related to P. belone from New Caledonia, Loyalty Islands, Vanuatu, Tonga, Fiji, the Wallis and Futuna. The two species can be distinguished by the following aspects:

— The number of mesogastric spines is one (rarely 2) in P. belone and 3 or 4 spines in P. lophia .

— The distolateral spine overreaches the end of the segment 3 in P. belone , whereas this spine only reaches midlength of the segment 3 in P. lophia .

— The distomesial spine of the antennal segment 2 reaches or slightly overreaches the end of the antennular segment 1 in P. belone ; however, this spine clearly does not reach the end of the antennular segment 1 in P. lophia (see Cabezas et al. 2009).

The genetic divergences between P. belone and P. lophia were 1.71% (16S rRNA) and 4.56% (ND1). Distribution. Solomon Islands, between 135 and 325 m.
