( Fig. 2 )

Type genus

Cleonardopsis K.H. Barnard, 1916 .

Diagnosis

Head. Deeper than long; lateral cephalic lobe subquadrate, head truncated apically; anteroventral margin straight, anteroventral margin moderately recessed, anteroventral margin moderately excavate; rostrum short or moderate length; eyes absent. Body without setae; dorsally carinate. Antenna 1 subequal in length or longer than antenna 2; peduncle with sparse slender setae; peduncular article 1 longer than article 2; article 2 longer than article 3; article 3 shorter than article 1; accessory flagellum minute, 1­articulate; calceoli present. Antenna 2 medium length; peduncle with sparse slender setae or none; flagellum longer than peduncle.

Pereon. Coxae 1–4 longer than broad, overlapping, coxae not ventrally acute. Coxae 1–3 progressively larger. Gnathopod 1 subchelate; carpus shorter than propodus. Gnathopod 2 subchelate; coxa smaller than but not hidden by coxa 3; carpus short, shorter than propodus. Pereopods none prehensile. Pereopod 4 coxa not ventrally acute, with small posteroventral lobe. Pereopod 5 coxa without lobes; basis slightly expanded. Pereopod 6 basis slightly expanded. Pereopod 7 basis expanded, subrectangular.

Pleon. Urosome urosomites not carinate. Uropods 1–2 apices of rami without robust setae. Telson weakly cleft; dorsal or lateral robust setae absent; apical robust setae absent.

Generic composition
