ABSTRACT. A rare ground beetle species Chlaenius (Agostenus) quadrisulcatus (Paykull, 1790) is registered for the Moskovskaya Oblast for the first time. The species was found in May 2019 in the east of the region at the Orekhovo-Zuevsky district, on Sphagnum raft, in a lake-marsh biotope of coniferous-broadleaf forest. Considering the rarity of this species, it is proposed to include it in the Red Book of the Moskovskaya Oblast.
KEY WORDS: Ground beetle, Chlaenius (Agostenus) quadrisulcatus, new record, Moskovskaya Oblast.
