Remarks. There are quite a few papers with illustrations of D. pruvus , but most of them are photos of the habitus or drawings of the general appearance of the copulatory organs of both sexes. Illustrations showed the structure of the male palp without details. We decided to fill this gap: see Figs 1–4 .

The embolic division of the male palp of D. pruvus is characterized by a complete set of the micronetine sclerites (sensu Saaristo & Tanasevitch 1996): boat-shaped radix, terminal apophysis, lamella characteristica and embolus. The palpal structure of D. pruvus slightly resembles that in, for example, Drapetisca socialis (Sundevall, 1833) . The elongated and hardly sclerotized integuments of the epigyne in the female also resembles that in the Palaearctic D. socialis , as well as that in East Asian Epigyphantes epigynatus (Tanasevitch, 1988) and Vagiphantes vaginatus (Tanasevitch, 1983) . The genus Doenitzius is a rather peculiar representative of micronetines, the taxonomy, composition and relationships of which require further study.

Material examined. 8♂ 12♀ ( ZMMU), CHINA: Liaoning Prov., env. of Fengcheng City, Mt. Phoenix , ca 40°23’N, 124°05’E, 280–550 m a.s.l., 16–18.X.2017, Y.M. Marusik leg.

Distribution. Occurs in southern part of the Maritime Province of Russia (pers. data), Korea, and Japan ( WSC 2024) ( Fig. 9B ). In China the species was known only from the Jilin Province ( Li & Lin 2016). New record for the Liaoning Province and westernmost in the entire range.
