( Figs. 14F, 17I)

Paramunida polita Macpherson, 1993: 456 , fig. 5 ( Indonesia, 281–502 m). — Baba 2005: 198, 302 (key, synonymies, Kei Islands and Moro Gulf off Zamboanga, 200−366 m). — Baba et al. 2008: 173 (list of occurrences).

Material examined. Indonesia. Kei Islands . KARUBAR. Stn CP 06, 05°49'S, 132°21'E, 22 October 1991, 287– 298 m: 1 F 12.0 mm (holotype, MNHN-Ga3354), 8 M 8.7–14.2 mm, 7 F 8.2–13.0 mm (MNHN- Ga3399). — Stn CP 25, 05°30'S, 132°52'E, 26 October 1991, 336– 346 m: 2 M 10.4–11.6 mm, 3 F 9.6–10.6 mm. — Stn CP 35, 06°08'S, 132°45'E, 27 October 1991, 390– 502 m: 1 M 11.6 mm, 1 ov. F 12.4 mm, 1 F 10.4 mm (MNHN-Ga3405) .

Philippines. MUSORSTOM 1. Stn 20, 13°59'N, 120°20'E, 21 March 1976, 208– 222 m: 1 ov. F 7.0 mm .

Diagnosis. Rostrum triangular, larger than supraocular spines, with thin dorsal carina; with row of small epigastric spines behind rostral spine; 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 well-developed spine. Median cardiac region with 3 or 4 well-developed spines. Few and short setae along anterior branch of cervical groove. Sternal plastron with few 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 about 1.3 times longer than broad with distomesial spine spiniform, slightly overreaching end of segment 3, distolateral spine nearly reaching end of segment 3; segment 3 about 1.5 times as long as broad. Base of P1 carpus without bundle of setae. P2 propodus 6–7 times as long as wide, and 1.5 times dactylus length.

Remarks. Paramunida polita is closely related to P. leptotes from Japan and Taiwan. 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 . In addition, the segment 3 of the antenna is more slender in P. leptotes ; as the length of the segment is more than half instead of less than half the breadth; and the breadth of the segment 3 is less than instead of more than half that of the segment 2. The genetic divergences between P. leptotes and P. polita were 3.84% (16S rRNA) and 12.81% (ND1).

Distribution. Indonesia, Kei Islands, Philippines and Moro Gulf off Zamboanga, between 200 and 502 m.
