Summary: | Kussakinella gen. nov. Type species . Austrosignum spinosum Kussakin, 1982. —Here designated. Species included . Kussakinella spinosa (Kussakin, 1982), comb. nov. Diagnosis . Body with nearly parallel margins in male (female not known). Head front margin broadly rounded in dorsal view. Pereonites with mid-dorsal conical spines. Pleotelson lateral margins smooth; posterior margin with acute apical spine-like projection. Eyestalks robust, apex rounded, slightly wider than long. Antennula article 1 shorter than eyestalk. Antenna article 3 shorter than article 4. Mandible palp absent. Pereopod I carpus triangular, with 2(?) straight robust setae posteriorly; propodus with simple setae only on posterior margin. Pereopod II carpus and propodus posterior margin with a few short robust setae. Uropod endopod straight, apex truncate. Etymology . The genus is named in honour of the late great Russian isopodologist Oleg G. Kussakin. Remarks . We have not seen the single specimen reported by Kussakin. Our analysis of the species is based on Kussakin’s illustrations (1982: fig.10–11). We are in doubt about the number of robust setae on the posterior margin of pereopod I carpus. Kussakinella spinosa differs from all other species treated herein by its slender body with nearly parallel margins, dorsal spines on pereonites, and a spine-like apical projection on the pleotelson.
