Remarks. The most recent family diagnoses for the Epimeriidae is that of Coleman (2007), Coleman and Barnard (1991), and Barnard and Karaman (1991).

Based on the genetic data presented in the following and a detailed morphological evaluation of the weak morphological separation criteria between Epimeriella and Epimeria we herewith synonymize Epimeriella with Epimeria . Since we transfer the species Epimeriella macronyx Walker, 1906 ; Epimeriella scabrosa Barnard, 1930 ; Epimeriella truncata Andres, 1985 ; Epimeriella victoria ( Hurley, 1957 a) and Epimeriella walkeri Barnard, 1930 to the genus Epimeria , we herewith give a new genus diagnosis.

The diagnosis has been broadened from that given by Barnard and Karaman (1991) since it now included characters formerly predominantly occurring in the genus Epimeriella such as a smooth body and the laminar, none triturative pars molaris.

Diagnosis. Body covered with teeth or processes or body poorly armed, almost smooth. Antenna 1 peduncular article 2 shorter than 1. Accessory flagellum present or absent. Mouthparts projecting quadrately. Upper lip incised or almost entire; epistome not very broad. Mandibular incisor ordinary, toothed, setal row present; molar blunt, strong, triturative or simple, conical or laminar. Lower lip inner lobes absent, outer lobes relatively broad. Hypopharyngeal gap sometimes widened. Maxilla 1 palp 2-articulate, article 2 ordinary. Maxilla 2 inner plate without facial row of setae. Maxilliped inner plate narrower but as long as outer plate, latter elongate; palp article 2 narrow and unproduced; palp article 4 well developed, unguiform or serrate. Coxae 1–4 progressively longer; coxae 4–5 forming ventral arc; coxa 4 long, polycuspidate. Gnathopods alike, articles 5–6 elongate, subchelate (typical), sometimes simple. Telson incised or cleft.
