Leiopus nebulosus, a common highly variable European species, has been described from Gotland (Sweden) as Cerambyx nebulosus by Carl Linné in 1758 [▽]. Its endemic Caucaso-Anatolian subspecies L. nebulosus caucasicus, occuring in Azerbaijan, Armenia, Georgia, Russia: Southern Federal district and Turkey, has been described as Liopus caucasicus from Tbilisi (Georgia) environs by Ludwig Ganglbauer in 1887 [✮]. It is currently considered a subspecies of L. nebulosus [❖]. Biology of L. nebulosus caucasicus is very similar to the nominotypical subspecies.

Body length:5 - 10 mm
Life cycle:1 - 2 years
Adults in:April - August
Host plant:polyphagous on deciduous trees (Carpinus, Quercus, Castanea, Fagus, Alnus, Prunus)
Distribution:an endemic subspecies to the Caucasus Mts. (Azerbaijan, Armenia, Georgia, Russia: Southern Federal district, Turkey)

Depicted male beetles were beaten from dead broadlaf tree branches in Kamennomostsky (Каменномо́стский) environs (Maykopsky district, Republic of Adygea, North Caucasus, Southern Federal district, Russia) on July 5-20, 1998.
