Extended diagnosis. Body relatively narrow. Five to six pairs of dorsolateral appendages. Six to eight appendages of oral veil. Five to six appendages (apparently equal in size) of rhinophoral stalks. Lateral papilla of rhinophoral sheaths present. Rhinophores with 15–18 lamellae. Lip papillae 15–25. Basal colour brownish with scattered distinct opaque white dots. Dorsal processes of jaws inclined posteriorly at approximately 55° to the longitudinal axis of the jaw body and 0.47 of its length. Masticatory processes apparently bear indistinct denticles (may possess ridge-like structures). Radula with up to 39 rows of teeth. Central tooth with up to 14 small denticles and reduced furrows. Up to nine lateral teeth with up to nine denticles. Ampulla folded twice. Bursa copulatrix is large and rounded. Seminal receptaculum small placed distally at a moderately short distance from the vaginal opening. Prostate discoid with about 25–30 alveolar glands. The vas deferens is moderate in length, penis long and twisted. Body length upto 19 mm.

Distribution. Arctic – Kara Sea to Laptev Sea, Russia.

Bathymetry. 10–20 m depth, occasionally deeper.

Remarks. This recently described species is easily distinguished from its congenerics ( Korshunova et al., 2016a).This is a true Arctic species that so far has been recorded only from the Laptev Sea and Kara Sea.
