Koponen, M., Triapitsyn, S. V. and Vikberg, V. 2018: Report on Ooctonus (Hymenoptera: Mymaridae) of Finland, with additional new records from some other European countries. – Sahlbergia 24(2): 14–24.
2574 specimens of the fairyfly genus Ooctonus Haliday, 1833 (Hymenoptera: Chalcidoidea: Mymaridae) from Finland were examined and identified to species, an annotated list of which is given. These were mainly collected by M. Koponen and V. Vikberg while some earlier ones by W. Hellén; the bulk of them are deposited in Zoological Museum, Finnish Mu- seum of Natural History, University of Helsinki, Finland, and a few are in V. Vikberg’s private collection. Most specimens were determined by M. Koponen and V. Vikberg while some also by S. V. Triapitsyn in 2016 and 2017. Ooctonus novic- kyi Soyka, 1950 is newly recorded from Finland, and its previously unknown male is described and illustrated; an updated key to the males of the European species of Ooctonus is provided. Now all six known European species are found in Fin- land; we also include new distributional records of five of them from some other European countries.
Key words. Hymenoptera, Chalcidoidea, Mymaridae, Ooctonus, biodiversity, Finland, Europe.

Using this opportunity, we also list some recently identified (by M. Koponen and S. V. Triapitsyn) specimens of five species of Ooctonus from some other European countries from several museum collections, including those in FMNH collected by M. Koponen. Those representing new country records are marked by an asterisk (*).
Distribution maps for all species are proviced as Maps 1–6. Dot colours on the maps represent the year of the latest record in a 10x10 km2 square: white < 1901 or year unknown; red 1901–1974; green 1975–1999; blue > 1999.
