P5 ( Fig. 23d): dactylus ( Fig. 23f) 4.5–5.5 as long as wide, with 10–15 spiniform setae on flexor margin; propodus 18.7–24.0 times as long as wide, 4.5–5.5 times as long as dactylus. ABDOMEN. Third abdominal somite with moderately convex dorsal profile. Sixth abdominal somite 0.56 times as long as carapace, 1.7 times as long as fifth somite, shorter than telson. TELSON ( Fig. 23i). 2.5–3.5 times as long as wide, with five pairs of dorsal spinules and pair of dorsolateral spinules; posterior margin with small median process, rounded, with 8–10 very long intermediate plumose setae longer than lateral ones. MALE PLEOPODS. Pl1 ( Fig. 23j): endopod rounded, 1.4 times as long as wide, reaching 0.22 times length of endopod, no appendix. Pl2 ( Fig. 23k): appendix masculina reaching 0.77 times length of endopod; appendix interna reaching 0.75 times length of appendix masculina. PRE- ANAL CARINA ( Fig. 23g). High, with a spine. UROPODAL DIAERESIS ( Fig. 23h). With 15–17 spinules. EGGS. Ovigerous females with small eggs, size: 0.30–0.38 × 0.18–0.23mm.
