Head. Head anteroventral margin strongly recessed, extending behind posterior margin of eye. Eye oval, medium size, about one quarter head length, situated entirely within the lateral lobe. Mandible palp article 3 distinctly shorter than article 2, spatulate, widest subdistally. Antenna 1 peduncular article 1 shorter than article 3; flagellum with 8 articles and bearing aesthetascs on alternate articles; accessory flagellum absent. Antenna 2 long, more than half body length; flagellum distinctly longer than peduncular article 5 with 7 articles.

Pereon. Coxae 15 longer than broad, sparsely fringed with short setae; coxa 1 unproduced. Gnathopod 1 carpus subequal to propodus; propodus between 1.5 and 3 x as long as wide, posterodistal margin evenly rounded. Gnathopod 2 basis anterior margin with a few short setae; carpus with distinct free posterior expansion; propodus less than 2.5 x as long as carpus, posterodistal margin without robust seta, palm with a single excavation; dactylus longer than half length of propodus. Pereopod 3 merus with many very long setae on anterior margin; propodus less than 4 x as long as broad. Pereopod 5 basis slightly expanded, distinctly longer than broad; with few setae on anterior margin. Pereopods 5–7 dactylus each with accessory spine on the anterior margin.

Pleon. Epimeron 3 posterodistal margin rounded. Uropod 1 peduncle without distoventral spine; rami subequal in length. Uropod 2 peduncle without distoventral spine; rami distinctly unequal in length. Uropod 3 peduncle slender, subequal to the outer ramus; inner ramus vestigial; outer ramus with terminal fine setae. Telson without robust setae.
