Euracmaeops angusticollis, a common species of Siberian taiga forests, extends on the western edge of its distribution area as the rarity to Poland (Białowieża Forest) and Belarus. However, it can be said that E. angusticollis is a very rare and sporadically recorded species west of the Urals, with a center of occurrence in the Northeast Eurasia. The larvae develop under the bark of stems and branches of dead conifers (mostly in Pinus spp., rarely in spruce Picea abies). Before pupation, the larva makes a pupal cell in the wood under the bark, life cycle is at least 2 years. Adults, diurnal and anthophilous, are active from June to August [▽].

A new genus Euracmaeops gen. n. (type species: Leptura marginata Fabricius, 1781) has been proposed by Mikhail Danilevsky in 2014 [❖] for the Palaearctic species formerly included in the American genus Acmaeops LeConte, 1850 with 4 new combinations: E. angusticollis (Gebler, 1833), comb. n., E. marginatus (Fabricius, 1781), comb. n., Euracmaeops septentrionis (C. G.Thomson, 1866), comb. n., and E. smaragdulus (Fabricius, 1793), comb. n.

Body length:♂♂ 5.9 - 8.6 mm / ♀♀ 6 - 8.8 mm
Life cycle:2 years
Adults in:June - August, in Poland mainly in June
Host plant:conifers (Pinus, Picea)
Distribution:from Poland in the west to Siberia, northern China, North Korea and Sakhalin in the east


The depicted beetles were collected on flowers in the middle course of the river Rogatka (Рогатка) at Yuzhno-Sakhalinsk (Sakhalin oblast, Sakhalin, Far Eastern Federal District, Russia) on July 18, 2011.
