- Dorsal ocelli present, strongly pigmented only at inner margins; pigment cups separated by distance of about 1.7 ocelli diameters., rounded in dorsal view.
- 3 pairs of strongly chitinized, nipple-like cuticular processes located ventrally anterior to oral papilla.
- A1 moderately long, with 4 apparent segments, intersegmental division between putative segments 3-4 marked only by a constriction. Antennular length representing 15.8% of total body length, and 25% as long as cephalothorax. length ratio of segments 23.6 : 14.2 : 140.5 : 52.7 (includes fused 3rd and 4th segments).
- P5 formed by single lobe, bearing 3 terminal setae, plus 4th seta on proximal 1/3 of inner margin.
- Urosome comprising 5th pedigerous somite, genital double-somite plus 2 free somites.
- Genital doubble-somite representing 46% of urosome, with incomplete dorsal suture.
