Genus Vinogradovopleustes n. gen. Figures 2–7. Type material: Holotype: X 47110 Cr 2210. Paratypes X 47111 Cr 2211, X 47112 Cr 2212, X 47113 Cr 2213. Type locality: Okhotsk Sea, Far East of Russia (55°00'00''N 142°02'40''E, 130 m). Type species. Vinogradovopleustes punctatum sp. nov . Species . Vinogradovopleustes punctatum sp. nov . from the shelf of north-east Sakhalin Island (Okhotsk sea). Diagnosis . Pereon, pleon, and urosome 1 carinate middorsally. Urosome segment 2 occluded dorsally. Head, rostrum strong. Antenna 1, peduncular segment 1 enlarged, with small anterodistal and posterodistal acute processes. Antenna 2, peduncular segment 2 with long sharp posterodistal process. Upper lip, apical lobes slightly asymmetric. Mandible, left lacinia 10–11 dentate, right lacinia lacking; molar strong, columnar; blades 5–6 on left, 9–10 on right. Maxilla 2, inner plate with subapical inner marginal seta. Coxae 1–3 each with few (3–5) posterodistal cusps; coxae 5–6 posterolobate; coxa 5 with lateral posteror protrusion (stopper). Pereopods 1 & 2 (gnathopods 1 & 2), pereopod 2 slightly the larger. Palmar margin of propodus smoothly oblique; carpus, posterior lobe medium, merus without distinct posterodistal tooth. Pereopods 5–7 unequal in form; pereopod 5 shortest; basis of pereopod 5 linear, without posterior lobe; basis of pereopod 6 with narrow posterior lobe; basis of pereopod 7 broadened. Pleon plates 1–3 acutely produced postero-ventrally. Telson medium long, distally rounded, without paired pennicilate setae. Distribution. The shelf of northern Sakhalin, Okhotsk Sea. Relationships : Vinogradovopleustes n. gen. is similar to the genus Rhinopleustes Hendrycks & Bousfield, 2004 by the presence of a dorsal carination. Vinogradovopleustes differs from Rhinopleustes by the following combination of character states: antenna 1, peduncular segment 1 without strong anterodistal processes; coxae 1–3, posterodistal cusps multiple; pereopod 5, base linear (see also key). Etymology : The genus Vinogradovopleustes is named in the memory of the famous Russian carcinologist Michail Vinogradov, combined with the older genus name Pleustes . The name is masculine in gender. : Published as part of Labay, Vjacheslav S., 2018, Vinogradovopleustes punctatum, new genus, new species, a pleustid amphipod from the Okhotsk Sea (Crustacea: Amphipoda: Gammaridea: Pleustidae: Pleusymtinae), pp. 159-168 in Zootaxa 4392 (1) on page 160, DOI: 10.11646/zootaxa.4392.1.8, http://zenodo.org/record/1195284 : {"references": ["Hendrycks, E.
