Entomologists – the Austro-Hungarian army prisoners of World War I in Siberia and the Russian Far East

The participation of European entomologists from among the Austro- Hungarian army prisoners of World War I in the research of the Siberian and Amur entomofauna is considered. Despite the fact that they were doing this in conditions of lack of freedom, their mass collection yielded appreciable results. The biographical information about Karl Ferdinand Mandl (1891– 1989), Stepan Jurechek (1877–1940), Hermann Frib (1877–1947), Josef Michel (1890–1963) and Alfred Biener (1892(?)–1954), which are known from publications of entomologists processed their collections or materials, is given. Some little-known events from the activities in the South Ussuriysk branch of the Amur department of the Russian Geographical Society in Nikolsk-Ussuriysk, and in the life of Evgenia Nikolaevna Klobukova-Alisova (1889–1962) and Alexei Ivanovich Kurentsov (1896–1975) are described. The translation of memories on this time by A. Biener is included in the Appendix.

Orthoptera of the Komsomolsky Nature Reserve and the wildlife preserve «Udyl» in Khabarovsky krai

Twenty species of Orthoptera in 19 genera and four families are recorded from the Komsomolsky Nature Reserve for the first time and only four species in two families are found in the wildlife preserve «Udyl». The species riches of Orthoptera recorded from the natural reserves in the Amur Region of the Russian Far East are compared. Number of species in Komsomolsky and Bastak reserves is almost the same (15–20 species), while 51 species of Orthoptera are known from Khingansky Reserve.

History of study of the andrenid bees (Hymenoptera, Andrenidae) fauna of Mongolia

A critical review of publications on bees of the family Andrenidae (Hymenoptera, Anthophila) of Mongolia is carried out for the first time. A complete list of 45 species recorded from Mongolia by various authors is provided. Totally six species (Andrena – 4, Panurginus –2) have been described from Mongolia and all of them are valid now. According to current data, Mongolian Andrenidae includes 38 species from three genera (Andrena – 32, Panurginus – 5, Melitturga – 1). Records of 15 species of the genus Andrena are problematic and needs to be confirmed.

New data on tardigrades of the genus Milnesium (Tardigrada, Eutardigrada, Milnesiidae) from the Russian Far East, obtained using the method of molecular barkoding

A study of terrestrial tardigrades of the genus Milnesium Doyère, 1840 collected in Russky Island (Primorsky kray, Vladivostok) was carried out using the methods of integrative taxonomy, including the analysis of morphological and molecular biological data. Three species are recorded from this island, of which M. inceptum Morek, Suzuki, Schill, Georgiev, Yankova, Marley et Michalczyk, 2019 is new for the fauna of Russia. New data were obtained on the distribution and genetic diversity of M. tardigradum Doyère, 1840. The third species, Milnesium sp., is similar to M. tardigradum but differs from latter in the presence of a characteristic thickened cuticle zone at the base of the claws of the fourth pair of legs and is probably a new for science species.

Review of entomological researches in the Shantar Islands, Khabarovsky krai

The data on researchers and collectors of insects visited Shantar Islands (Khabarovsky krai, Sea of Okhotsk) from 1844 to 2020 are summarized in chronological order. According to our database 205 species in 39 families and seven orders of insects were recorded from Shantar Archipelago till now. Coleoptera, Diptera, Hymenoptera and Lepidoprea are the most studied orders of insects.

Study on Pterostichus neglectus A. Morawitz, 1862 (Coleoptera: Carabidae)

Two forms of the carabid beetle Pterostichus (Phonias) neglectus A. Morawitz, 1862 are disclosed in Amur region of the Russian Far East. These forms differ by the color of legs and palpus, as well as by the shape of male genitalia. Probably, these forms belong to the separated species.

Orthoptera and Dermaptera of the Sikhote-Alin State Nature Reserve

An annotated list of 37 species of Orthoptera from five families and three species of Dermaptera from two families reliably recorded from the Sikhote-Alin State Nature Reserve is given. All species of Dermaptera and 15 species of Orthoptera are new for the fauna of this reserve.

First record of the suborder Archostemata (Coleoptera) from Lazovsky Reserve, Primorsky krai, Russia

For the first time a species of the suborder Archostemata, Tenomerga mucida (Chevrolat, 1844) (Coleoptera: Cupedidae), is listed for the fauna of the Lazovsky Reserve.

Review of the family Caligidae (Crustacea, Сореpoda, Siphonostomatoida) of the fauna of Vientam

An annotated list of 30 species in 10 genera of the family Caligidae collected from fishes in the waters of Vietnam in 1960, 2011, 2013 is given. The data on localities and hosts are provided for all species. Vietnamese Caligidae is registrated from 29 fishe species from 26 genera, 21 families, and six orders. The most diverse genera of copepods are Caligus (16 species) and Parapetalus (4 species). Tropical and subtropical species of Caligidae dominate in the fauna of Vietnam, while only Caligus bonito, C. pelamydis, C. lacustris and Caligodes laciniatus are distributed in both Boreal and Subtropical zones.

Distribution of two species of dung-beetles (Coleoptera: Scarabaeidae, Aphodiini) in Primorsky krai

The use of the method of removing the substrate allows not only to obtain new information about the structure of assemblies of coprophagous beetles, but also to clarify the distribution of certain species. In Russia, two species of dung-beetles were previously known only from the Khasansky district of the Primorsky krai. At present, Aganocrossus urostigma (Harold, 1862) is found in the Shkotovsky district, and Sinodiapterna songrini (Stebnicka et Galante, 1992) is reported from the Shkotovsky, Partizansky, and Anuchinsky districts of Primorsky krai for the first time.
