Dendronotus dudkai Ekimova et al. (2016): 33 –38, Figs 9–11 (synonym of D. primorjensis ). Extended diagnosis . Body narrow. Fiveto nine pairs of branched dorsolateral appendages (including 2–3 smaller pairs). Five to twelve oral veil appendages. Four to five appendages (internal middle and posterior ones longest) of rhinophoral stalks.Lateralpapillaof rhinophoral sheaths present. Rhinophores with 8–12 lamellae.Fiveto 12lip papillae.Basalcolournonuniformlyreddishbrownwithfewopaquewhite stripes between dorsolateral processes to more uniformly olive almost without white pigment, or almost lacking general pigmentation. Dorsal processes of jaws inclined posteriorly at approximately 45–47° to thelongitudinalaxis of thejawbodyand 0.48 of itslength. Masticatory processes bear denticles and ridge-like structures. Radula with up to 41 rows of teeth. Central tooth with deep furrows and with upto 18 (common range 12–14) distinct denticles. Up to nine lateral teeth with up to eight denticles. Ampulla moderately narrow with several windings or folded loops. Bursa copulatrix large, rounded. Seminal receptaculum small placed distally at a moderately short distance from the vaginal opening. Prostate discoid with range 12– 19 alveolar glands. The vas deferens is moderate in length, penis relatvely long, curved. Reported body length upto 35 mm. Distribution . NW Pacific, common in the northern part of the Sea of Japan, at both the Russiancoastandat Hokkaidoonthe Japanese coast (Korshunova et al., 2016b, 2019b). Bathymetry . 3–20 mdepth. Remarks . Dendronotus dudkai Ekimova et al. (2016) isasynonymof D.primorjensis according to morphological, molecular and geographical data. For discussion see Korshunova et al.
