Dimensions : TT 0.90 mm ± 0.04, CW 0.48 mm ± 0.03, CL 0.50 mm ± 0.04. Carapace ( Fig. 17a ): carapace globose; dorsal spine posteriorly directed; rostral spine straight, anteriorly directed, slightly shorter than dorsal spine; small lateral spines present; a pair of dorsal setae present; eyes sessile. Antennule ( Fig. 17b ): uniramous, endopod absent; exopod unsegmented bearing 3 terminal aesthetascs of unequal size and 1 terminal seta. Antenna ( Figs 17a,c ): similar in size to rostral spine; protopodal process with 2 rows of spines, larger in the inner margin; endopod absent; exopod developed but shorter than protopodal process, with 2 very reduced, 1 small and 1 stout, long-terminal setae. Maxillule ( Fig. 18f ): epipod seta absent; coxal endite with 6 (5 sparsely plumose, 1 plumodenticulate) setae; basial endite with 5 (1 subterminal, plumodenticulate; 2 stout, terminal sparsely plumose; 2 stout, terminal plumodenticulate) setae, 2 acute teeth also present; endopod 2-segmented, proximal segment with 1 (simple) seta, distal segment with 5 (1 subterminal, simple + 4 distal, plumodenticulate) setae; exopod seta absent. Maxilla ( Fig. 18g ): coxal endite bilobed bearing 5 (1 simple, 2 sparsely plumose, 2 plumodenticulate) setae + 4 (3 sparsely plumose, 1 simple) setae, basial endite bilobed with 5 (2 sparsely plumose, 3 plumodenticulate) + 5 (plumodenticulate) setae; endopod bilobed with 2 (unequal, sparsely plumose) + 3 (unequal, sparsely plumose) setae; scaphognathite (exopod) margin with 4 plumose setae and 1 long distal stout process. First maxilliped ( Fig. 18h ): basis with 10 setae (arranged 2 sparsely plumose; 2 simple; 1 sparsely plumose, 2 simple; 1 sparsely plumose, 2 simple); endopod 5-segmented with 2 (simple), 2 (sparsely plumose), 1 (sparsely plumose), 2 (1 simple, 1 sparsely plumose), 5 (1 subterminal simple + 1 terminal simple, 3 terminal plumodenticulate) setae; exopod unsegmented with 4 terminal plumose natatory setae. Second maxilliped ( Fig. 18i ): basis with 4 setae (arranged 1 sparsely plumose, 1 sparsely plumose, 1 sparsely plumose, 1 sparsely plumose); endopod 3-segmented with 1 (simple), 1 (plumodenticulate), 6 (1 subterminal denticulate + 3 subterminal simple, 2 terminal sparsely plumose) setae; exopod unsegmented with 4 terminal plumose natatory setae. Third maxilliped : absent Pereiopods : absent Abdomen ( Figs 17a,d ): 5 somites; somite 2 with 1 pair of dorsolateral processes directed anteriorly, somite 3 with 1 pair of dorsolateral processes directed ventrally; postero-lateral processes from round to acute in somites 1–5, indented in somites 3–5; a pair of median postero-dorsal setae in somites 2–5. Telson ( Figs 17d,e ): a pair of minute lateral spines present; small setae distributed in scattered patches, small spines in fork margins, except for the tips; forks large, divergent; posterior margin with 3 pairs of stout setae, the median one with proximal larger spinulae on external margin.
