Description. Based on neotype female. Body shape normally laterally compressed; cuticle calcification absent. Eye medium (1 ⁄ 5 – 1 ⁄ 3 head length). Antenna 2 longer than head and first 3 pereonites; peduncular articles narrow. Maxilliped outer plate distally acute/arcuate; palp dactylus present and distinct. Pereonite 1 sternite without papillose process. Gnathopod 1 not sexually dimorphic; simple; merus and carpus not expanded; propodus subrectangular; palm absent; dactylus longer than palm. Gnathopod 2 not sexually dimorphic; chelate; narrow; merus and carpus expanded posteriorly; propodus “mitten-like”; palm obtuse; smooth; dactylus shorter than palm. Pereopods 3–7 long (½ length of body); simplidactylate. Pereopod 4 carpus similar in length to pereopod 3 carpus, dactylus similar to pereopod 3 dactylus. Pereopod 7 posterodistal lobe present. Gill 2 lobate, not incised. Gills 3–5 simple or lobate, smaller than gills 2 and 6. Gill 6 lobate, anterior margin convoluted, subapically incised along posterior margin. Oostegites long (length greater than 2× width), strongly setose, setae with simple smooth tips. Epimera 1 to 3 not convergent. Epimeron 2 subequal in length to epimeron 3. Epimeron 3 posteroventral margin smooth, posteroventral corner with small subacute tooth. Pleopod 1 well developed, biramous, rami subequal in length to peduncle; inner ramus with 13 articles; outer ramus with 10 articles. Pleopod 2 well developed, biramous, rami subequal in length to peduncle; inner ramus with 8 articles; outer ramus with 3 articles, outer ramus with 1–5 articles. Pleopod 3 reduced, rami absent. Uropod 1 not sexually dimorphic; peduncle with 4 robust setae on peduncle; inner ramus subequal in length to outer ramus, with 2 robust setae on the margins, with 1–2 robust setae, with 5 apical robust setae; outer ramus without marginal robust setae, with 4 apical robust setae. Uropod 2 not sexually dimorphic; peduncle with 3 robust setae; inner ramus subequal in length to outer ramus, with 2 marginal robust setae, 5 apical robust setae; outer ramus without marginal robust setae, with 3 apical robust setae. Uropod 3 peduncle with 1 robust seta; ramus shorter than peduncle, ramus linear (narrowing), with 2 robust setae. Telson as broad as long, apically incised, with marginal and apical robust setae, with 3–5 robust setae per lobe.
