27. LEIOPUS NEBULOSUS (LINNAEUS, 1758)

Examined material: In research time four specimens were collected in three localities: Kaliningrad, Kaliningrad Zoo, 54°71´83´´N 20°46´98´´E, the imago was obtained 6. VI.2010 from larva collected 21. V.2010 under the dry branch (12 ńm in diameter) on living apple tree (1 ex., leg. and reared V. Alekseev); the Curonian Spit, 23 km NNE of Zelenogradsk, 55°9´91´´N 20°74´54.9´´E, 10.VII.2010 (1 ex., light trap in the mixed forest with Populus tremula , Alnus glutinosa , Betula sp. and Pinus sylvestris , leg. A. P. Shapoval); 21.VII.2010 (1 ex., ibidem, leg. A.P. Shapoval); 3 km NNE Zelenogradsk, 54°95´74´´N 20°51´53´´E, 10.VIII.2010 (1 ex., sweeping in the humid mixed forest with Betula sp. , Alnus glutinosa , Quercus robur and Pinus sylvestris , leg. V. Alekseev).

Comments: After division of Leiopus nebulosus sensu lato in two separate species and describing of the new sibling species L. linnei ( Wallin et al. 2009) , all the earlier published data on this taxon need to be redeterminated or confirmed. The matherials collected before 1945 from the region ( Bercio & Folwaczny 1979) are not available and it is impossible to known which species ( L. nebulosus or L. linnei or both taxa) was sampled by German coleopterologists. The materials presented earlier by Alekseev (2007) as L. nebulosus were reexaminated and redeterminated according to recent key. Also the materials of the lasts years were added. To the all evidence L. nebulosus is more scarce and local in its distribution across the Kaliningrad region. In the Baltic Region Leiopus nebulosus is reported from coastal areas of Norway, Sweden, Finland, Denmark ( Wallin et al. 2009), Estonia ( Bukejs & Balalaikins 2011) and from Latvia (BarƱevskis et al. 2009). The species is also known from Poland, Austria and Ukraine (Gutowski et al. 2010). At present, the findings of this species in the Kaliningrad region are unique for the Russian territory and thus the species is recorded for the Russian fauna for the first time.
