Chironomids of the subgenus Chaetocladius s. str. from the Amur River basin are revised using both morphological characters and molecular data. Three new species, C. egorych sp. nov., C. lopatinskiy sp. nov. and C. yavorskayae sp. nov., are described and figured. The pupa of C. fedotkin is described for the first time. Adult males of C. ligni and C. piger, little-known in the Far East, are redescribed and annotated, and key to males of the Chaetocladius s. str. from the Amur River basin is provided. A reference 658 bp barcode sequence from a fragment of the mitochondrial gene cytochrome oxidase I (COI) was used as a tool for species delimitation. Comparisons with corresponding regions of COI between 5 species in the subgenus produced K2P genetic distances of 8.3–12.6%, values well associated with interspecific variation. Molecular data were also used for the reconstruction of the phylogenetic relationships within the subgenus Chaetocladius s. str.

Calamagrostis are described from the Russian Far East. Chromosome numbers are reported for two new taxa. Calamagrostis burejensis Prob. et Barkalov, 2n = 28 (sect. Calamagrostis), C. zejensis Prob., 2n = 28 (sect. Deyeuxia), and C. × amgunensis Prob. (C. amurensis Prob. × C. neglecta (Ehrh.) G. Gaertn., B. Mey. et Scherb. s. l.) are described from the Amur River basin (Amur Region or Khabarovsk Territory); Arundinella rossica Prob. (sect. Hirtae) and Calamagrostis kozhevnikovii Prob. et Prokopenko (sect. Calamagrostis) from Primorye Territory.

A long-term study implemented in the Amur River basin enabled us to generate an updated checklist of 606 valid species in Chironomidae (Diptera) which are composed of 129 genera and six subfamilies, with 98 (17%) described new species belonging to 46 genera. Among the 98 recently described species, 46 ones (45%), were considered as possible endemics and sub-endemics. The numbers of species and genera by subfamilies is as follows: Podonominae (3 species; 3 genera), Tanypodinae (17; 9), Diamesinae (25; 11), Prodiamesinae (7; 3), Orthocladiinae (307; 57) and Chironominae (247; 46). The higher numbers of species (421 and 410, respectively) were recorded in the Lower and Middle parts of the Amur River basin, as compared with the Upper part of the basin. Most of the recorded chironomids (387 species, 67%) are Palaearctic in distribution, while others (191, 33%) are widely Holarctic. Species with Palaearctic distribution mostly have the following range types: East Palaearctic continental (23%); East Palaearctic continental-insular (20%); Palaearctic transpalaearctic (14%); Palaearctic amphi-Eurasian (10%).

The discovery of Neolithic (i.e. pottery-containing) components at the Ust-Karenga 12 site in northern Transbaikal brought to light new data on the appearance of pottery in Siberia. Excavations and geoarchaeological studies identified the pottery complex in layer 7, 14C-dated to c. 12 180–10 750 BP (charcoal dates) and c. 11 070–10 600 BP (pottery organics dates). The pottery is thin and plant fibre-tempered; vessels are round-bottomed and with a comb-pattern design. Ust-Karenga 12 thus preserves by far the earliest Neolithic assemblage in Siberia, and is only slightly younger than the Initial Neolithic complexes of the Amur River basin, Russian Far East (c. 13 300–12 400 BP).

Nemoura sirotskii sp. n. (Plecoptera, Nemouridae) is described as a new stonefly species from the tributary streams of Zeya Reservoir (Amur River Basin) in the south of the Russian Far East. Detailed descriptions and illustrations are provided for the larvae and adult specimens. The diagnostic characters distinguishing it from sympatric species N. arctica are discussed.

The radiocarbon age of the earliest pottery from Russian Far East—Gromatukha and Osipovka cultures—is between around 13,300 BP and around 10,400 BP. This shows that the Amur River basin was one of the centers of origin of pottery in East Asia, at the end of the Pleistocene. Today, there are three areas within East Asia with pottery-associated 14C dates between around 14,000 BP and 13,000 BP—southern China, the Japanese Isles, and Russian Far East.

Two new species of Beckidia Sæther, B. biraensis and B. connexa, from the Amur River Basin are described and figured as males. The male of B. tethys (Townes) is redescribed and figured and the species is recorded for the first time from Russia. The generic diagnosis is emended and a key to the males of Beckidia from the Holarctic Region is given.
