Material examined. 2 individuals (MO00178868, MMR BK7450): Munamjin-ri , Jugwang-myeon , Goseong-gun, Gangwon-do, Korea, 38°18′04.04″N, 128°34′10.08″E, 27 April 2021 ; 1 individual ( MMRBK7454 ): Munamjin-ri , Jugwang-myeon , Goseong-gun, Gangwon-do, Korea, 38°18′04.04″N, 128°34′10.08″E, 05 May 2021 ; 1 individual ( NIBRIV0000876678 ): Gonghyeonjin-ri , Jugwang-myeon , Goseong-gun, Gangwon-do, Korea, 38°21′15.21″N, 128°31′00 13″E, 22 February 2019 .

Diagnosis. Body elongate (length 11 mm, width 3 mm), laterally compressed, ground color opaque white or brown. Small whitish and yellowish dots and light brown and brown tuberculate scattered in mantle. Rhinophores lamellate, rhinophoral stalks long, with five appendages. Four to six pairs of highly branched dorsolateral appendages and decreasing in size towards tail. Foot narrow, rounded in front, narrowed towards tail.

GenBank accession number. OK143204.

Distribution. Korea, Japan, Russia.

Remarks. From morphological and molecular analysis, Dendronotus dudkai was synonymized with D. primorjensis by Korshunova et al. (2016). The examined specimens of the present study match the morphological features of D. primorjensis described by Korshunova et al. (2016).
