(Fig. 3)
Type genus
Parepimeria Chevreux, 1911.
Diagnosis
Head. As long as deep; lateral cephalic lobe subtriangular, subacute apically; anteroventral margin concave, anteroventral margin moderately recessed, anteroventral margin deeply excavate; anteroventral corner rounded; rostrum short, moderate or long; eyes absent. Body without setae; dorsally carinate.
Antenna 1 shorter than or subequal in length to antenna 2; peduncle with many slender setae; peduncular article 1 shorter than article 2; article 2 shorter than article 3; article 3 subequal to or longer than article 1; accessory flagellum minute, 1 articulate; callynophore absent; calceoli absent. Antenna 2 long; peduncle with many slender setae; flagellum longer than peduncle.
Pereon. Coxae 1–4 longer than broad, overlapping, coxae 1–4 ventrally acute. Coxae 1–3 progressively larger. Gnathopod 1 simple; coxa ventrally acute or subacute; carpus shorter than or subequal to propodus. Gnathopod 2 simple; coxa smaller than but not hidden by coxa 3; carpus long, subequal in length to propodus.
Pereopods nonprehensile. Pereopod 4 ventrally acute, with small posteroventral lobe. Pereopod 5 coxa equilobate; basis slightly expanded. Pereopod 6 longer than pereopod 7; basis slightly expanded. Pereopod 7 shorter than pereopod 5; basis slightly expanded.
Pleon. Urosome urosomites 1 or 1–2 carinate. Uropods 1–2 apices of rami with weakly developed robust setae. Telson entire; dorsal or lateral robust setae present; apical robust setae absent.
Generic composition
Parepimeria Chevreux, 1911.
Parepimeriinae (Parepimeria perda after Lowry & Myers 2003).
Remarks
Parepimeriinae differs from other amathillopsids in the concave anteroventral margin of the head, in the third peduncular article of antenna 1 which is subequal to or longer than peduncular article 1, the gnathopods which are long, slender and simple and uropods 1 and 2 in which the rami have apical robust setae.
Distribution
Southern Ocean.
