Comments: This species is sporadically distributed in the whole Baltic and Fennoscandian region ( Silfverberg 2004). The species is considered to be rare in Lithuania ( Ferenca et al. 2002) and Latvia ( Barševskis et al. 2008). On the territory of the northern part of the former East Prussia, it has been recorded from Rauschen [Svetlogorsk], Neuhäuser [Mechnikov], Pillau [Baltiysk], Warnicken [Lesnoe], Georgenswalde [Otradnoe], Löwenhagen [Komsomol’sk], Insterburg [Chernyakhovsk], Königsberg [Kaliningrad] and Neuhausen [Gur’evsk] ( Bercio & Folwaczny 1979). This beetle (as also the above-mentioned species) occurs and develops in yeast sap and under the bark of deciduous trees (primarily oaks).
