Diagnosis.

Gnathopod 1 coxa anteroventral corner projected roundly, posteroventral corner with a notch; carpus 1.2× longer than propodus; propodus palm convex, serrate and defined by posterodistal corner; dactylus stout, inner margin serrate, apical nail present. Left gnathopod 2 (larger), propodus, distolateral crown with 3 spines. Right gnathopod 2 (smaller), merus with acute posterodistal projection; palm straight, serrated, defined by a long robust seta; dactylus, inner margin serrate, apical nail present. Pleonites and urossomites with dorsal spines. Epimeral plate 3, posteroventral corner strongly produced, posterior margin minutely serrate. Uropod 3, outer ramus 2× longer than peduncle, 10× longer than inner ramus. Telson deeply cleft (80% of telson length), each lobe with 3 dorsal and at least 2 lateral robust setae.

Remarks.

Dulichiella anisochir had not yet been recorded for the Marine State Park of Laje de Santos, this being the first record for the sampled location. The species recorded, D. anisochir , has 3 strong spines on the distolateral crown of propodus of the largest male gnathopod 2 and 9 dorsal spines on each pleosomite 1–3, versus 4 strong spines on distolateral crown of gnathopod 2 and 7 dorsal spines on each pleosomite 1–3 in both other species, D. ankeri and D. brunoi .
