Towards the taxonomy of Corynoneura Winnertz (Diptera: Chironomidae: Orthocladiinae) from the Russian Far East and Eastern Siberia.

The genus Corynoneura Winnertz is partly revised on the basis of materials from the Russian Far East and Eastern Siberia. Adult male of a new species, C. sikhotealinensis sp.

Morphological description and DNA barcoding of Hydrobaenus laticaudus Sæther, 1976 (Diptera: Chironomidae: Orthocladiinae) from Amur River basin (Russian Far East).

Illustrated redescription of adult male and description for the first time of pupa and fourth instar larva, as well as DNA barcoding, of Hydrobaenus laticaudus Sæther in comparison with close related known species of Hydrobaenus Fries, and an updated part of a key to species of Hydrobaenus from the Russian Far East are 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. For the estimation of interspecific distances and constructing detailed Bayesian tree within Hydrobaenus, we have obtained DNA barcoding for the two other species, H.

Three species of Hydrobaenus Fries (Diptera: Chironomidae: Orthocladiinae) from Belarus.

Illustrated descriptions of adult male, pupa and fourth instar larva of Hydrobaenus molleri sp. nov., adult male of H.

Morphological description and DNA barcoding of Chaetocladius (Chaetocladius) elisabethae sp. nov. (Diptera: Chironomidae: Orthocladiinae) from the Moscow Region.

Illustrated descriptions of the adult male, pupa and fourth instar larva, as well as DNA barcoding results of Chaetocladius (Chaetocladius) elisabethae sp. nov. in comparison with closely related species of Chaetocladius s.

New or little-known species of s. str. Kieffer, 1911 (Diptera: Chironomidae: Orthocladiinae) from the Amur River basin (Russian Far East).

Chironomids of the subgenus Chaetocladius s. str. from the Amur River basin are revised using both morphological characters and molecular data.
