Morphometric study of wing venation in the recent Trichoceridae - an application to the fossils?

• Ewa KRZEMIŃSKA

Abstract:

The wings of 12 species of the genus Trichocera MEIGEN and representatives of the genera: Diazosma BERGROTH and Nothotrichocera ALEXANDER were measured,  22 characters per wing. Sexual dimorphism in wings was stated and found to coincide with discerning the species and genera. Within the genus Trichocera, the male wing characters - in spite of their great similarity - may be used for tracing the inter-species relations. Clustering procedure applied to the male representatives of the genera reflects the generic assignment.
