Pronocera sibirica, a species of North-East Palaearctic forest belt occuring in Russia, Kazakhstan, Korea and North China, has been described from Öskemen/Ust-Kamenogorsk (Kazakhstan) as Callidium brevicolle by Friedrich August Gebler in 1833 [❖]. But due to preoccupation of name "brevicolle" is valid species name "sibiricum" (Callidium sibiricum) used as nomen novum by the same author in 1848 [✧]. Larvae of P. sibirica develop in dead/dying branches or weakened tops of the mature host trees, spruce (Picea) is strongly preferred host tree in Siberia. They feed subcortically creating meandering galleries deeply impressed in alburnum (up to 2.0 mm) and plugged with fine frass. Before the second overwintering larvae enter the wood and leave transversely elongate-oval opening on surface plugged with frass. After the second overwintering larvae make hook-shaped pupal cell in the end of gallery, pupate and hatch during May - June. Life-cycle 2 years. Adults, active from June to early September, lead a cryptic mode of life, do not visit flowers and can be found on the host trees [✩].

Body length:9 - 13 mm
Life cycle:2 years
Adults in:June - September
Host plant:polyphagous in coniferous trees (Picea, Pinus, Abies) but very rare also in deciduous trees (Acer)
Distribution:Russia (East Siberia, Far East), Kazakhstan, Korea, Mongolia, North China
