DISTRIBUTION. Palaearctic species. Known from Latvia, Lithuania, Ukraine, Poland and some regions of European Russia (incl. North Caucasus) [ Ul’yanin, 1869; Vishnyakova, 1959, 1964; Danka, 1960, 1964; Martini, 1975; Savel’ev, 1997; Golub, 2005, 2016; Szawaryn et al., 2020; Ostrovsky et al., 2023].

NOTES. A large (c. 6.5– 8 mm) barkfly; the largest species found in Belarus. In the field the combination of large size and mainly colourless wings makes the species easily recognisable. Found mainly on branches of deciduous and coniferous (evergreen) trees and bushes.
