Abstract
The male imago of Chaetocladius longivirgatus sp. n. is described and diagnosed against a refined characterization of the species understood as C. suecicus (Kieffer) since Edwards (1929). The two species are separated by both morphology and partial COI sequences (DNA barcodes). An additional single male specimen shows pairwise genetic distances to C. suecicus and C. longivirgatus sp. n. as high as those between the latter two species, thus may represent a third European member in this species group.Morphologically, however, that male is inseparable from those of C. suecicus.
