Diagnosis. Rostrum spiniform, larger than supraocular spines, with thin dorsal carina; margin between rostral and supraocular spines straight or slightly concave. Spinules on gastric and hepatic regions usually not forming groups, lacking scaly striae and with few short uniramous setae. Mesogastric region with 3 welldeveloped spines. Cardiac region with 3 or 4 well-developed spines in midline. Few and short setae along anterior branch of cervical groove. Sternal plastron smooth, few striae on sternite 4. Lateral margin of antennular segment 1 with distal slender portion slightly shorter than proximal inflated portion. Antennal peduncle with anterior prolongation of segment 1 spiniform; segment 2 nearly twice longer than broad, with distomesial spine spiniform, clearly overreaching end of segment 3 but not reaching end of antennal peduncle, distolateral spine not reaching end of segment 3; segment 3 more than twice longer than broad. Base of P1 carpus without bundle of setae. P2 propodus about 18 times as long as wide, and about 1.4 times dactylus length.

Remarks. Paramunida amphitrita is related to P. cretata from Waterwitch Bank, Wallis Islands and Fiji and P. thalie , from Vanuatu, New Caledonia, Loyalty Islands, Chesterfield Islands, Fiji and Queensland (see below under Remarks for those species).
