Diagnosis.
Rostrum smaller than or at most equal to supraocular spines, with small thin dorsal carina; margin between rostral and supraocular spines clearly convex. Spinules on gastric and hepatic regions usually not forming groups, lacking scaly striae and with few short uniramous setae. Mesogastric region without distinct spines. Median cardiac region with small spines. Few and short setae along anterior branch of cervical groove. Sternal plastron with few short striae on sternite 4, smooth 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 twice longer than broad, with distomesial spine spiniform and curved, overreaching end of antennal peduncle, distolateral spine not reaching midlength of segment 3; segment 3 elongate, 4 times longer than broad. Base of P1 carpus without bundle of setae. P2 propodus about 15 times as long as wide, and about 1.5 times dactylus length.
Remarks.
Paramunida curvata
belongs to the group of species with the rostral spine smaller than the supraocular spines. However,
P. curvata
can be differentiated from the other species of the group (
P. hawaiiensis
,
P. microrhina
,
P. setigera
, and
P. tenera
) by having the margin between rostral and supraocular spines clearly convex, whereas this margin is straight or slightly concave in the other species.
Genetically the closest relative is
P. scabra
from
Hong Kong
, East and South
China
Sea (Dongsha),
Indonesia
,
Philippines
,
Taiwan
,
Japan
, and
Australia
(off Central
Queensland
). The differences were 6.66 % (16S rRNA) and 9.22 % (ND1).
Distribution.
Fiji
and
Vanuatu
, between 229 and
417 m
.
