Paramunida evexa Macpherson, 1993

( Figs. 13B, 16H)

Paramunida evexa Macpherson, 1993: 450 , fig. 2 ( Indonesia, 174–226 m). — Baba 2005: 198, 302 (key, synonymies, Ambon Sea, 128–238 m). — Baba et al. 2008: 172 (list of occurrences).

Material examined. Indonesia. Kei Islands . KARUBAR. Stn CP 67, 08º58.59’S, 132º07.20’E, 01 November 1991, 233– 246 m: 2 M 10.2–11.3 mm, 1 ov. F 9.0 mm. — Stn CP 82, 09º32’S, 131º02’E, 4 November 1991, 215– 219 m: 1 ov. F 11.9 mm. — Stn CP 86, 09º26’S, 131º13’E, 04 November 1991, 223– 225 m: 1 F 10.4 mm (holotype, MNHN-Ga3214), 6 M 9.4–10.6 mm, 2 ov. 11.5–11.7 mm, 4 F 8.4–11.0 mm .

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 forming groups arising from scale-like striae and with few short uniramous setae. Mesogastric region with 3 or 4 welldeveloped spines. Median cardiac region with 3 or 4 well-developed spines. Few and short setae along anterior branch of cervical groove. Sternal plastron squamate, with numerous striae on sternites 4–7. Lateral margin of antennular segment 1 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, with distomesial spine of segment 2 blunty produced, overreaching end of segment 3, small distolateral spine not reaching midlength of segment 3; segment 3 as long as broad. Base of P1 carpus without bundle of setae. P2 propodus about 8 times as long as wide, and 1.3–1.4 times longer than dactylus.

Remarks. Paramunida evexa is related to P. antipodes from Eastern Australia. The two species can be easily differentiated by the following characters: the mesogastric region has only one spine (rarely 2) in P. antipodes , whereas there is a row of 3 or 4 mesogastric spines in P. evexa ; the distomesial spine of the antennal segment 2 is blunty produced in P. evexa , whereas it ends in a distinct spine in P. antipodes ; the sternal plastron has numerous striae in P. evexa , being smooth in P. antipodes .

Paramunida evexa is also close to P. scabra from Hong Kong, East and South China Sea (Dongsha), Indonesia, Philippines, Taiwan, Japan, and Australia (off Central Queensland) (see under Remarks for that species).

Distribution. Indonesia ( Ambon, Kei Islands), between 128 and 246 m.
