Section Short Communications

A new species, Asyndetus bykovskyi sp. n., from the Astrakhan State Nature Biosphere Reserve (Russia) is described. This species can be distinguished from Asyndetus chaetifemoratus by the structure of hypopygium, partly yellow femora and the position of the apical section of vein M1 at the apex of the wing.
