Rhithrogena klugei sp. nov. (male, female and larva) are described from Far East of Russia. The Far Eastern species of Rhithrogena belong to two groups: lepnevae and sibirica. The species group sibirica is represented by the East Palaearctic species R. sibirica Brodsky 1930. The lepnevae species group includes R. lepnevae Brodsky 1930, R. bajkovae Sowa 1973 and R. klugei sp. nov. in the Far East and Siberia, and two species which can be found in the Russian Far East, R. piechockii Braasch 1977 from Mongolia, and R. ingalik Randolph and McCafferty 2005 from Alaska. The species group sibirica differs from lepnevae species group in that its larvae present a rounded projection on gills II–VI on the posterior-dorsal margin, whereas the imagines present a shoot at the base of the penis lobes. The larva of R. klugei sp. nov. differs from those of R. bajkovae and R. lepnevae in their form of gill I and in the ratio of the length to the width of gills III–IV. The male imago of the new species can be distinguished from others of the lepnevae species group by the absence of the latero-dorsoventral tooth on the penis lobes.

Stygomomonia (S.) manchurica sp. n. (Acari: Hydrachnidia: Momoniidae) from the Kedrovaya River, Primory Territory of the Russian Far East is described. The affinity of the new species to its congeners is discussed with emphasis on biogeographical relationships. An annotated checklist of the subgenus Stygomomonia and geographical map of the distribution of Palaearctic species of this subgenus is compiled using published records.

Victrix svetlanae sp. n. is described from Russian Far East, Khabarovsk Krai. The new species belongs to the subgenus Poliobrya Hampson, 1908. New species is most similar to V. umovii (Eversmann, 1846) and V. patula (Püngeler, 1907) but differs in both external and genital characteristics. This is the first record of the genus Victrix in the Far East.

Capnia khingana sp. n. (Plecoptera: Capniidae) is described as a new brachypterous species from the Lesser Khingan Range south of the Far East of Russia. Detailed descriptions and illustrations are provided for both sexes. According to the diagnostic characters of the male epiproct, C. khingana sp. n. may be tentatively assigned to the C. atra species group.

Three species of the Palaearctic genus Harpocera Curt, are distributed in the Far East of Russia H. koreana Jos. is recorded from Russia for the first time, the hitherto unknown males of H. choii Jos. and H. koreana Jos. are described and compared with H. orientalis Kerzh. from the Kuril Islands. A key to the three Far Eastern species is given.

Larvae, males and females of a new species from the minimax species-group, Tarsonemus striatus n. sp. (Acari: Tarsonemidae) are described from the galleries of, and phoretic on, the bark beetle Polygraphus proximus Blandford, 1894 (Coleoptera: Curculionidae: Scolytinae) in the Far East of Russia.

A new species, Baetis pentaphyllus sp. nov., is described on the basis of larvae from the Far East of Russia (type locality Bolshoi Garmakan River). Larvae of Baetis pentaphyllus sp. nov. may be distinguished from other Baetis species by the presence of only five pairs of tergalii on segments III–VII. The mitochondrial COI sequence obtained from the described species was compared with the data present in GeneBank and BOLD. The DNA barcodes allowed discrimination of B. pentaphyllus sp. nov. from other species of Baetis with available sequence data. The average interspecific K2P distances were 10–15%, which are values well above those associated with intraspecific variation. COI sequences as well as 36 morphological larval characters were analysed using Bayesian inference to relate the described species to the recognized species-groups of the Baetis genus. B. pentaphyllus sp. nov formed a sister clade to B. vardarensis + B. lutheri which belong to the Baetis lutheri species-group.

The canaliculatus species group of Stenus (Nestus) is redefined. Four new Palaearctic species of the group are described and illustrated: S. (N.) alopex sp. nov. from the Putorana Highland and Taymyr Peninsula, Russia; S. (N.) canalis sp. nov. from SE Siberia and the Russian Far East; S. (N.) canosus sp. nov. from the Narat Mt Ridge, Chinese Tien Shan; S. (N.) delitor sp. nov. from C & SE Siberia. New distributional data as well as brief analyses of old records for fourteen species described earlier are provided from both Palaearctic and Nearctic material. S. (N.) milleporus Casey, 1884 (= sectilifer Casey, 1884) is revalidated as a species propria. S. (N.) sphaerops Casey, 1884 is redescribed; its aedeagus is figured for the first time; the aedeagus of S. (N.) caseyi Puthz, 1972 as well as aedeagi of eight previously described Palaearctic species are illustrated anew. A key for the identification of all the known Palaearctic species of the group is given. A morphology and ecology based analysis of the main evolutionary trends within the group is provided. A lectotype is designated for S. (N.) melanopus Marsham, 1802; its Siberian and NE European records are supposed to be erroneous; the monotypic melanopus species group is erected.

We describe a new mite species from the Far East of Russia—Proctogastrolaelaps subsolanus Joharchi & Marchenko sp. nov. (Acari: Melicharidae). The new species was collected from soil-litter on the shores of the Tunaycha Lake and Sea of Okhotsk in Sakhalin Island. The important morphological characteristics of the genus Proctogastrolaelaps are revised.
