This study was supported by the Ministry of Science and Higher Education of the Russian Federation within the framework of the Federal Scientific and Technical Program for the Development of Genetic Technologies for 2019–2030 (agreement № 075-15-2021-1345, unique identifier RF193021X0012).

Annotation:

Two new monotypic genera are described: Pseudositeroptes trachi gen. and sp. n. and Neodiroptes sibiriensis gen. and sp. n. (Acari: Prostigmata: Pygmephoridae), collected under the thin bark of a rotting birch twig lying on the ground in Western Siberia, Russia. A female of Sevastianovella lacidus (Livshits, Mitrofanov and Sharonov) is redescribed based on the type material and a specimen from Western Siberia. The genera Sevastianovella Livshits, Mitrofanov and Sharonov and Diroptes Kaliszewski are rediagnosed. Species Diroptes bohemicus (Mahunka, 1967) comb. n., D. albidus (Livshits et al., 1988) comb. n., D. digitariae (Flechtmann, 1971) comb. n., D. spinisetus (Livshits et al., 1988) comb. n. and D. tauricus (Khaustov and Khaustov, 2022) comb. n. are removed from Sevastianovella. A key to the genera of Pygmephoridae with a 5-segmented leg I in females is provided.
