Description. Body. Body shape without loss or gross modification of appendages on one side of the body; in dorsal view without peduncular articles of antenna 1 or 2 contiguous with coxal margins.

Head. Head not capable of lateral rotation (laterally encompassed, abutting or fused to pereonite 1). Antenna 1 inserting on head anteriorly and/or dorsally to antenna 2, minute or well developed; not as follows: reduced to 2 articles with second article expanded and scalloped. Antenna 2 well developed. Mouthparts not forming suctorial cone or proboscis. Mandible not projecting anteriorly and together forceps-like; molar forming prominent triangular process projecting beyond body of mandible with spines along distal margin, or not forming prominent triangular process projecting beyond body of mandible with spines along distal margin, may be vestigial or absent; palp present. Maxilliped endite conspicuous.

Pereon. Pereonites 6-7 pereonite 7 distinct dorsally, free. Coxae extending ventrally and laterally to overhang the coxa-basis articulation of the pereopods. Coxa 1 and pereonite 1 fused. Pereopods 6-7 pairs readily apparent; 1-3 or 1-7 not prehensile. Pereopods 5-7 without flattened setose articles andor dactyls modified or absent.

Pleon / Pleotelson. Pleonites and pleotelson with pleonites 1-5 fused with conspicuous lateral sutures, pleotelson not fused to pleonites 1-5. Pleopods 5 pairs present. Pleopod 2 of males not consisting of an enlarged peduncle with a geniculate endopod and a small muscular exopod. Uropods positioned proximally on pleotelson; distinct from pleopods, not forming operculum over pleopodal chamber (although may be folded ventrally below pleotelson). Peduncle not forming an elongate clavate article with rami reduced or absent; fused to endopod. Endopod present, not claw-like (acute and recurved) andor posteroventral in position. Exopod present; not folded dorsally over pleotelson.
