Diagnosis.

Rostrum well developed, usually ventrally with teeth or rows of setae. Thoracic sternites 6-8 each with paired conspicuous prominences, teeth or protuberances ( Fig. 3A ). Pleomere 6 posterolateral process usually terminating in small tooth. Telson with longitudinal row of spiniform setae located on dorsolateral ridges. Eyestalks subpyriform or kidney-shaped, cornea distinctly longer and wider than eyestalk. Antennular stylocerite with proximolateral projection, distally acuminate or rounded; article 2 usually with minute spiniform setae ( Fig. 6A ); outer flagellum with distal portion (distal to aesthetasc-bearing portion) usually well developed, consisting of numerous articles. Article 1 of mandibular palp with prominent expansion on inner distal margin ( Fig. 6B ). Maxilliped 2 with podobranch. Maxilliped 3 with or without exopod. Pereopod 1 fingers minute or completely reduced. Pereopod 2 subequal or unequal; basis with small process on lateral surface ( Fig. 6C ); carpal articulation greatly variable, but never tri-articulated. Arthrobranchs usually present on maxilliped 3 and pereopods.
