. Carapace with narrow triangular spiniform rostrum reaching beyond midlength of eyestalks. Eyestalk with subterminal cornea in distal third, diameter spanning over half of eyestalk width. Major chela with merus inferior keel bearing proximal hooked spine and adjacent ancillary spine, otherwise microdenticulate. First pleonal tergite crossed dorsally by smooth transverse furrow in anterior half, posterior sclerite narrowing anteriorly to acute middorsal terminus, sixth with neither angular nor arched projection in anterior third of lateral margin. Telson length slightly exceeding width, lateral margins converging posterior to weak lateral lobes, posterior margin truncate, lacking median spine. Uropodal endopod elongate ovoid with low longitudinal ridge; exopod anterodorsal plate obscure to obsolescent, lateral margin lacking incision. Diagnostic sequence data for the COI mitochondrial gene is provided under GenBank www.ncbi.nlm.nih.gov/genbank) accession number OQ413315.

As in its congeners, the antennular peduncle is both heavier and shorter than the antennal peduncle, and the antenna bears a short bladelike dorsal scaphocerite where its second article joins to the third. Typical of the genus, its second maxilliped is comparatively small, with a straplike exopod carried against the internal surface of the slightly longer endopodal merus, and a small epipod originating at its base.
