Rostrum 0.17 times carapace length, falling slightly short of distal corneal margins, triangular in dorsal view, slightly ascending, tip rounded. Carapace with anterior middorsal spine moderately large, epigastric in position (arising at 0.1 of carapace length), not reaching rostral base; posterior middorsal spine arising at 0.6 of carapace length; shallow orbital cleft discernible; antennal spine directed forward in dorsal view, weakly ascending in lateral view; branchiostegal spine moderately strong, directed forward in dorsal view. Pleomeres 1–4 without middorsal carina, pleomere 5 with trace of middorsal carina; pleura of pleomeres 1–3 without conspicuous tooth or spine marginally; pleomere 6 with blunt submedian carinae. Telson with posteromedian process moderately produced, subacute. Eyestalk (including cornea) almost as long as wide; dorsal tubercle relatively small, rounded, papilla-like. Antennular peduncle reaching beyond midlength of antennal scale; article 1 short, blunt distolateral process; stylocerite falling far short of distolateral process of article 1; article 2 with short, blunt distolateral process. Antennal scale 0.5 times as long as carapace, 2.5 times as long as wide; lateral margin gently concave; distolateral spine reaching as far as rounded distal lamella. Maxilliped 3 with ultimate article 6.9 times as long as wide. Pereopods 4 and 5 relatively slender; dactyli narrowly subspatulate, margins not forming sharp edges, bearing numerous setae on lateral and mesial margins and extensor surface.
