E–G). Inner coxal seta pinnate in legs 1 and 2, small and pinnate in leg 3, and rudimentary in leg 4. Outer seta on basis of legs 2–4 small and naked. Inner distal spine on basis of leg 1 large, longerthan first endopodal segment, with minute spinules on both margins. Outer distal spine on first exopodal segment of legs 1–4 and second exopodal segment of legs 2–4 strong and slightly curved outwards. Distal spine on third exopodal segment of leg 1 stout and pinnate along outer margin. Spines on third exopodal segment of legs 2–4 pectinate along outer margin. Armature formula for legs 1–4 as in generic diagnosis.
. This species may be characterised by the extremely long caudal rami which are about 9 times as long as wide and 3.7 times as long as the anal somite. These proportions differ from all known congeners. The possession of 2 small exopodal setae of equal length on the antenna and the prominent proximal tubercle on the outer margin of the mandibular basis are additional diagnostic features of the new species.
