DIAGNOSIS.—Stages Other Than Copulatory Male (copulatory males unknown): *Pereonites 4–6 about as long as wide in dorsal view (poor condition ot specimen prevents further comment). *Pleonites progressively narrower, forward edge of epimeres sloping gradually posteriorly; epimeres bearing about 3 small hairs. *Pleotelson long, about 1.4 times wider than long; uropods borne close to body of pleotelson; sides convex anterior and posterior to uropods. *Chelae with large fingers; *fixed finger with large, distinct, and somewhat flat-topped distal teeth; dactylar teeth 2 or 3 in number, partially fused with dactylus, and anteriorly directed. Pereopodal setae slender, with very fine setules; short, terminal propodal spines slightly curved distally and with relatively large teeth, at least on pereopods III and IV; long terminal propodal spines absent. Pereopod VII with only a few short, subterminal propodal spines (4 in Lang’s (1968) figure 87g). Pleopods with distinct terminal row of endopodal setae. Both proximal incisive spines of mandibles setulated on both sides.
