Material examined. 1 unknown sex, AM P77830 ( JDT / LIZ 15); 3 unknown sex, AM P77733 ( JDT / LIZ 16); 1 unknown sex, AM P77829 ( JDT / LIZ 17).
Type locality. Off Lizard Head , Lizard Island, Queensland, Australia (14°40’S 145°28’E) GoogleMaps .

Maxilliped palp with 3 articles, outer plate extending beyond palp article 2.
Pereon. Gnathopod 1 and 2 similar; Gnathopod 1 carpus longer than propodus. Coxa 3 widened anterodistally. Pereopods 4–7, coxa wider than long. Pereopods 5–7 basis slender, not lobate.
Pleon. Pleonites 1–3 dorsally smooth. Epimera posteroventral angles rounded. Urosomites 1–2 with bidentate posterodorsal margins. Uropod 1 rami longer than peduncle, slender, equal in length, with long robust distal setae. Uropod 2 much shorter than uropod 1. Uropod 3 elongate, peduncle almost reaching apex of rami of uropod 1, with robust setae; rami subequal, very long, ovatolanceolate. Telson quadrate, deeply incised.
