20. SORONIA PUNCTATISSIMA (ILLIGER, 1794) Examined material: Recorded from two localities in the western part of the region: Zelenogradsk district , Otradnoe environs, 54°56´26.2´´N 20°8´27.1´´E, 03.VII.2009 (3 exx, on effluent oaks sap, old oak at the margin of a mixed forest, sympatric with 2 exx of closely-related S. grisea , leg. V. Alekseev); Bagrationovsk district, near the railway station “ 1312 km ”, 54°33´10´´N 20°9´30´´E, 07.VII.2009 (1 ex., under the bark of an oak of three hundred years old, leg. V. Alekseev) .

Comments: This species is sporadically but widely distributed in the whole Baltic and Fennoscandian region ( Silfverberg 2004). On the territory of the northern part of the former East Prussia, it has been recorded from Cranz [Zelenogradsk], Rauschen [Svetlogorsk], Warnicken [Lesnoe], Königsberg [Kaliningrad] and Heiligenbeil [Ladushkin] ( Bercio & Folwaczny 1979). This beetle is scarce due to its particular ecological niche – the species occurs and develops in yeast effluent sap of old oaks. The beetles are to be found also in the tunnels and galleries of Cossus spp. ( Lepidoptera , Cossidae ).
