13. TILLUS ELONGATUS (LINNAEUS, 1758)

Examined material: Hitherto recorded twice in 2010 only: Bagrationovsk district, near the railway station “ 1312 km ”, 54°56´98´´N 20°21´86´´E, 27. VI.2010 (3 exx, the humid Fageto-Quercetum forest, on the dried Fagus sylvatica colonizied by Ptilinus pectinicornis , leg. V. Alekseev); Zelenogradsk district, settlement Otradnoe, 54°91´72´´N 20°6´76´´E, 30. VI.2010 (1 ex., on the living Acer platanoides colonizied by Ptilinus pectinicornis , leg. V. Alekseev).

Comments: This species is widely distributed across the whole Baltic and Fennoscandian region and has been reported from all territories ( Silfverberg 2004) and from Belarus ( Alexandrovitch et al. 1996). On the territory of the northern part of the former East Prussia, it has been recorded from Rauschen [Svetlogorsk] and Königsberg [Kaliningrad] ( Bercio & Folwaczny 1979). The basic prey of this beetle are anobid species from genus Ptilinus ssp. (by our observation – Ptilinus pectinicornis ). The beetles occur in Juni-July on the inhabited by Ptilinus old and dried deciduous trees. In the Moscow region ( Russia) the beetle prefers as prey the associated with willow and aspen Ptilinus fuscus , also the fungivorous larvas of Dorcatoma and even the inhabited spruce larvas of Ips ( Nikitsky et al. 1996) .
