Diagnosis. Rostrum spiniform, smaller than supraocular spines, with thin dorsal carina; row of small epi- uniramous setae. Mesogastric and cardiac regions without well developed spines. 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 more than twice longer than broad, distomesial spine spiniform, exceeding antennal peduncle, distolateral spine not reaching end of segment 3; segment 3 twice longer than broad. Base of P1 carpus with bundle of setae. P2 propodus 12–14 times as long as wide, and 1.3–1.4 times dactylus length.

Remarks. Paramunida setigera is closely related to P. curvata from Fiji and Vanuatu. The two species can be easily differentiated by the shape of the rostrum. The margin between the rostral and supraocular spines is clearly convex in P. curvata , whereas this margin is straight or slightly concave in P. setigera . The genetic divergences were 9.57% (16S rRNA) and 13.37% (ND1).

The species is also related to P. tenera n. sp. from Fiji, Vanuatu and New Caledonia (see below under Remarks for that species).

Distribution. Philippines and Indonesia, between 170 and 289 m.
