diagnosis
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
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
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.
