“…Except for a combination of hypopygial characters given in the diagnosis, the adult male of Stempellina radoszkowskii differs from all known Stempellina by lower number of antennal flagellomeres. This character was recently analysed in extant and fossil species of the genus (Zakrzewska et al 2020), as well as in Stempellinella (Zakrzewska & Jankowska 2021). A distinct trend towards reduction of the number of flagellomeres (12 or less) in extant species relative to those of fossil is confirmed here.…”

This systematic review of non-biting midges of the tribe Tanytarsini is based on materials collected during Polish scientific expeditions to North Korea. Stempellina radoszkowskii sp. nov. is described. Brief illustrated redescriptions of adult males of further eight species, for the first time recorded from North Korea, are presented: Cladotanytarsus (Cladotanytarsus) sinjongensis Ree et Kim, 1988, Micropsectra joganplumosa Sasa et Okazawa, 1991, M. jokatertia Sasa et Ogata, 1999, Tanytarsus iriolemeus Sasa et Suzuki, 2000, T. oyamai Sasa, 1979, T. takahashii Kawai et Sasa, 1985, T. tamadecimus Sasa, 1980 and T. tamaundecimus Sasa, 1980. New synonyms are proposed: Micropsectra tonewdeea Sasa et Tanaka, 2002, syn. nov. [=Micropsectra atrofasciata (Kieffer, 1911)]; Micropsectra tusimalemea Sasa et Suzuki, 1999, syn. nov., M. tusimamenea Sasa et Suzuki, 1999, syn. nov., M. tusimaquerea Sasa et Suzuki, 1999, syn. nov. [=Micropsectra joganplumosa Sasa et Okazawa, 1991], and several further synonyms of the species reviewed are suggested. An annotated checklist of Tanytarsini so far reported from North Korea is given. A historical note on Polish scientific expeditions to Korea is also included.

Here we provide evidence for the presence of non-biting midges of the subfamily Chironominae in the Mesozoic, based on descriptions of exceptionally rare amber inclusions. The subfamily has already been reported, but based on a single and unspecified record from Late Cretaceous Taimyr amber (~84 Mya). That record is here revised and confirmed. Moreover, a new find in Burmese amber locates the temporal boundary of the subfamily back to the mid-Cretaceous (probably ~100 Mya). We describe two new genera assigned to the tribe Pseudochironomini: Mesoacentron gen. nov. with the species Mesoacentron kaluginae sp. nov. (Taimyr amber) and Palaeocentron gen. nov. with the species Palaeocentron krzeminskii sp. nov. (Burmese amber), the oldest known representative of the subfamily. The systematic position of the new taxa is discussed, and a key to the identification of adult males of extinct and extant Pseudochironomini genera is presented. Insights in the phylogeny and diversification tempo of the Chironominae and Pseudochironomini in the past are also provided.

Two new species of the genus Stempellinella Brundin, 1947, S. bazovae sp. nov. and S. chirka sp. nov., from Eastern Siberia and the Russian Far East are described. Illustrated redescriptions of males for further three species, S. coronata Inoue, Kawai et Imabayashi, 2004, S. edwardsi Spies et Saether, 2004, S. tamaseptima (Sasa, 1980) are given. Stempellinella ministylus Ree, 2015 is a new synonym Stempellinella coronata Inoue, Kawai et Imabayashi, 2004. Key to the males and pupae of the Russian Far East and Eastern Siberia Stempellinella species is provided.
