Contributions to the taxonomy and biogeography of the genus Dichagyris (subg. Dichagyris) Lederer, 1867 (Lepidoptera, Noctuidae, Noctuinae)

The taxonomically important characters and subgeneric subdivision of Dichagyris are presented with several historical nomenclatural considerations. Subdivision D. vallesiaca is revised based on the type material known subspecies. psammochroa group revised, description a new species, kurbatskyi from Kazakhstan, one subspecies, kopetdaghimena Kopet-Dagh massif. taftana species (D. guentereberti Afghanistan) two subspecies elborsasta safavida, different areas Iran). eastern sister humilis, hypotacta Afghanistan Pakistan, described. Major phylogenetic clades s. str. associated to western Palaearctic and/or Central Asiatic mountainous regions. Core allopatric speciation discussed taxonomic considerations outlook subgenera Yigoga Albocosta, as well.
