First record of Anopheles claviger (Meigen, 1804) (Diptera, Culicidae) in Karelia, Northwestern Russia.

Anopheles claviger (Meigen, 1804) (Diptera, Culicidae) is widespread in the western Palaearctic Region, but it was recorded in Karelia (Russia) for the first time. This record is one of the northernmost ones in the Palaearctic Region and Russia, updates the northern border of the An. claviger range. Mosquitoes were collected from July to September 2023 in the southern Karelia (the village of Gomselga, Kondopoga District, and Petrozavodsk) using Krishtal trap (from human) and Mosquito Magnet® trap (Pioneer design, Octenol as attractant). Seven females of An. claviger were collected in Gomselga; one specimen was sampled from Petrozavodsk City parks. Morphological identification of eight females was verified by COI and ITS2 sequences. Phylogenetic analysis of ITS2 and COI sequences confirmed the collected specimens to An. claviger s. s., clustering in both cases in a strongly supported clade clearly differentiated from the closely related species An. petragnani. The high diversity of An. claviger haplotypes from Karelia is in agreement with data from other geographical regions and shows that the records of this species in Gomselga and Petrozavodsk are not accidental.
