Isolated populations of the bush-cricket (Orthoptera, Tettigoniidae) in Russia suggest a disjunct area of the species distribution.

Phylogenetic analysis and assessment of the species status of mostly isolated populations of in south-western Russia occurring far beyond the accepted area of the species distribution in the Carpathian-Balkan region were performed. Using the mitochondrial DNA cytochrome oxidase subunit I gene fragment, we found a very low level of genetic diversity in these populations. Phylogeographic reconstruction did not support recent introduction events but rather historical range fragmentation.

Karyotypic diversity in the subfamily Eurytominae (Hymenoptera: Eurytomidae).

New data on the karyotype structure of five species of the subfamily Eurytominae are described, including the following species: Eurytoma rosae (2n = 20), E. robusta (n =7, 2n = 14), E. serratulae (n = 6, 2n = 12), E.
