ABSTRACT: Aulactinia vladimiri sp.n. is a small sea anemone described from shallow waters in vicinity of Petropavlovsk-Kamchatsky (Pacific coasts of Russia). The species has 48 (in fully developed specimens) tentacles which are usually bright pink. In contrast with internally brooding A. stella (Verrill, 1864), A. incubans Dunn, Chia et Levine, 1980 and A. vancouverensis Sanamyan, Sanamyan et McDaniel, 2013 (three species of the genus reported for North Pacific), the eggs of A. vladimiri sp.n. are incubated in an external brood chamber. The phylogenetic analysis for A. vladimiri sp.n. showed that A. stella is the closest related species with obtained sequences of mitochondrial genes 12S rRNA,16S rRNA and cytochrome oxidase III.
