Diagnosis. Distinguished by the comparatively large size, total length 3.6–3.9 and color pattern with a brown longitudinal stripe along inner margin of hemelytron and contrasting yellow scutellum and basal part of cuneus.

Distribution. The distributional area of this species mainly includes Mediterranean Region and central Europe, east to Poland, Turkey Crimea, and South Caucasus, namely Abkhazia, Georgia (Gori, Kakheti), northern Armenia (Akhtala, Alaverdi), northwestern Azerbaijan (Adzhikend, Saricali) ( Kiritshenko 1918, 1951; Akramovskaya 1959; Zaitseva 1998; Kerzhner & Josifov 1999). The species is currently unknown from the Northern Caucasus; introduced to North America.

Host and habitat. Campyloneura virgula inhabits different trees and shrubs of Caucasian deciduous forests. The species is exclusively or at least mainly predaceous, attacking psyllids, psocid nymphs, and eggs ( Wheeler 2001).

Discussion. Many European populations are constantly or typically parthenogenetic, and the same seems to be true for Caucasian and Crimean populations of this species. All specimens sampled from these areas kept in the Zoological Institute, Russian Academy of Sciences, are represented by females only.
