Euracmaeops smaragdulus, a species of coniferous forest zone of Northern Eurasia, is common in Siberia from Urals to Pacific Ocean coast. In Europe it is except Scandinavia and Russia very rare and local species, known only from Alps. Larvae develop under bark of dead coniferous trees (Picea, Pinus, Larix, Abies), before the second ovwervintering leave wood and create a pupal cell in the soil. Pupation during spring, complete life cycle 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. smaragdulus (Fabricius, 1793), comb. n., Euracmaeops angusticollis (Gebler, 1833), comb. n., E. marginatus (Fabricius, 1781), comb. n., and Euracmaeops septentrionis (C. G.Thomson, 1866), comb. n.

Body length:♂♂ 6.5 - 10.5 mm / ♀♀ 7.5 - 12 mm
Life cycle:2 years
Adults in:June - August
Host plant:coniferous trees (Picea, Pinus, Larix, Abies)
Distribution:Belarus, Finland, France, Italy, Latvia, Norway, Russia, Sweden, Switzerland, China, Mongolia

The depicted beetles were collected in Bol. Chara (Kodar Mts., 50 km NW of Novaya Chara, Kalarsky District, Zabaykalsky Krai, Russia) on July 5-10, 2001.
