Abstract
Enallagma cyathigerum var. rotundatum Bartenef, 1929, Leucorrhinia circassica Bartenef, 1929, and Aeschna juncea var. atshischgho Bartenef, 1929, were described by A.N. Bartenev (= Bartenef) in three papers published in 1929 and 1930. Their type locality was the same highland lake group near Krasnaya Polyana Town in West Caucasus, Russia, presently known as the Khmelevskie Lakes. Their type series most probably no longer exist. Topotypes of the two former taxa obtained in 2008 and 2013, respectively, were examined as well as a specimen supposedly of the third taxon, collected 36 km from the type locality. Based on these specimens, Enallagma cyathigerum rotundatum is concluded to be a valid subspecies and the senior subjective synonym of Enallagma risi Schmidt, 1961, and Leucorrhinia circassica to be a junior subjective synonym of Leucorrhinia dubia (Vander Linden, 1825). The status of Aeshna juncea atshischgho remains unresolved. Re-evaluation of available knowledge of the Palaearctic Enallagma spp. suggested downgrading Enallagma deserti (Selys, 1879) to the subspecies, Enallagma cyathigerum deserti.
