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 forming groups arising from scale-like striae and with few short uniramous setae. Mesogastric region with 1 (rarely 2) distinct spine. Cardiac region with 3 median well-developed spines in midline. Few and short setae along anterior branch of cervical groove. Sternal plastron with numerous striae on sternites 4–7. 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 about twice longer than broad with distomesial spine slightly mucronated, reaching or slightly exceeding antennal peduncle, distolateral spine nearly reaching end of segment 3; segment 3 as long as broad. Base of P1 carpus without bundle of setae. P2 propodus about 9 times as long as wide, and less than 1.5 times dactylus length. Remarks. Paramunida proxima is closely related to P. belone from New Caledonia , Loyalty Islands , Van- on sternite 4 in P. belone . Furthermore, the distomesial spine of the antennal segment 2 exceeds far beyond the antennal peduncle in P. belone , whereas this spine only reaches or slightly exceeds the antennal peduncle in P. proxima . The genetic divergences between both species were 5.53% (16S rRNA) and 10.94% (ND1). Paramunida proxima also resembles P. leptotes from Japan and Taiwan . The two species can be easily distinguished by the following aspects: the distomesial spine of the antennal segment 2 is long, and distinctly overreaching the antennal peduncle by the length of segment 3 in P. leptotes , whereas this spine terminates at the distal end of the peduncle in P. proxima ; the antennal segment 3 in P.leptotes is more elongate, being 1.5– 1.7 times longer than wide instead of being as long as wide in P. proxima . The genetic divergences between P. leptotes and P. proxima were 5.27% (16S rRNA) and 11.06% (ND1). Genetically the closest relative of this species is P. polita from Indonesia and the Philippines . These species can be easily distinguished by the length of the distomesial spine of the antennal segment 2 which clearly exceeds the antennal peduncle in P. leptotes , whereas this spine at most slightly exceeds the antennal peduncle in P. polita . The genetic divergences between P. leptotes and P. polita were 3.84% (16S rRNA) and 12.81% (ND1). Finally, P. proxima is also related to P. stichas from Solomon Islands , Vanuatu , New Caledonia , Fiji , Field Bank, Wallis Islands, and Bayonnaise Bank (see below under Remarks for P. stichas ). Distribution. Philippines , off Zamboanga , Mindanao, N of the Admiralty Islands, and Indonesia , Kei Islands, Solomon Islands and Vanuatu , between 135 and 402 m .
