Voucher specimens: 5 [23 km of the Curonian Spit, 18 July 1996; ibidem, 12 July 2011; Rybachii, 12 August 2002; the Baltic Spit, 08 July 2007; 3 km W Povarovka, 07 July 2018].

Kaliningrad Region: Zel. (“im Strandgebiet”, Pillau, Cranz); Zel.

Comments: The thermophilous species is usually an inhabitant of coastal pine plantations, where larvae feed in soil at the roots of plants. In the Region occurs on the Curonian Spit (locally numerous in edges of pine forests in vicinity of white dunes complexes near the Curonian Gulf), in coastal sandy areas of the western Sambian seacoast and on the Baltic Spit. In general, the species can be considered “sporadically distributed and abundant” in the Region. The species is listed in the Red Data Book of the Kaliningrad Region ( Dedkov & Grishanov 2010) as stenotopic beetle at the northern periphery of main distributional range. The real damage for sparce appropriate habitats is evident by increase of recreation too. Two colour forms of adults are encountered in the Region (with dark/ light brown cuticular pigmentation). The ratio of these forms by light trapping and the possible reasons of the sampled numbers are discussed in Alekseev & Shapoval (2012) .
