Local references: Bercio & Folwaczny 1979 (listed as Zilora sericea Strm. from present-day territory of Poland with remark “ ferruginea in the Seidlitz’s catalogue”).

Material: 3 km NE Zelenogradsk, 54.97°N, 20.52°E, 21.05.2020, 1 ex., on dead laying Pinus sylvestris, sphagnous bog.

Comments: This is the first formal report of the species from Kaliningrad region. The species is rare but comparatively wide-distributed in the Baltic Region (Tamutis et al. 2019). According to Nikitsky & Saitô (2014), Z. ferruginea (Paykull, 1798) and Z. obscura (Fabricius, 1794) (= Z. sericea) are two separate European species, which can presumable inhabit Kaliningrad region. Recent paper on Lithuanian melandryid beetles (Tamutis et al. 2019) showed that characters previously given for identifications of these species are variable and taxonomic status of the species is unclear.
