A 2 peduncle art 4 somewhat longer than art 5, flagellum with eight arts. Mouthparts: Mx 1 palp with one art; Mx 2 lobes in riding position; Md palp lacking; Mxp narrow, OP vanishing. Peraeon: Gn 1 subchelate, merus reaching end of carpus, distally not acute but rounded ending; propodus ovoid, palm oblique, about half length of propodus. Cx 2 anterior margin regularly convex, posterior margin concave; Gn 2 basis on anterior margin beset with many strong spines; carpus triangular, length subequal to width; propodus with nearly parallel margins, palm oblique, with many more or less deep incisions and humps; dactylus about half length of propodus. Cx 3 narrow, with parallel margins, distally slightly serrate, Cx 4 much wider than deep, ovoid. Peraeopods: P 3> P 4; P 3 basis with many setae anteriorly; P 5 basis rectilinear, dactylus ≥ half length of propodus; anterior margin of merus, carpus and propodus with many spines; P 6, 7 basis widened, merus on both margins with spines, posterior one widened and lengthened, but not reaching half length of carpus. Pleon: Ep 3 posteriorly bluntly produced; U 1 – 3 peduncle richly spinose; U 1 ped> subequal rami; U 2 rami unequal; P 3 ped> ramus, length of ramus art 1 = art 2; T with 5 pairs of spines marginally.
