2. TRECHUS AUSTRIACUS DEJEAN, 1831 * Examined material: A single individual of this species was caught using a light-trap on the Curonian Spit : 23 km NNE of Zelenogradsk, 55°5´21.6´´N 20°43´41.7´´E, 04.VII.2009 (1 ex., dry pine forest, leg. A. P. Shapoval) .

Comments: New species for the fauna of the Kaliningrad region. According to the catalogue of Silfverberg (2004), it has been reported from Latvia and Lithuania, and this species is also reported from Belarus (Aleksandrovitch et al. 1996). This species was unknown from the territory of the former East Prussia, though in the last paper dealing with the ground beetle fauna of the Kaliningrad region, the species is noted as possibly present (Alekseev 2008). This species represents a strong tendency towards synanthropisation – it lives in old cellars or outbuildings (Aleksandrovitch 1991).
