All pereonites separate. Coxae free. ANT I with short peduncle, large, straight, oval, lance-shaped, or conical first ART of flagellum, remaining ART rudimentary, hardly visible. ANT II thin, subequal to ANT I. MXP with short rounded inner lobe. Only P II chelate (with exception Cyllopus lucasi). P VII may be with reduced distal ART. Rami of all UR free.
Three genera:
