A key to species of Atopida
It is relatively difficult to identify species of Atopida . The main sources of problems with identification of Atopida are: significant sexual dimorphism, large infraspecific variability, similarity of male genitalia of several species groups, and the fact that bursal sclerites of females of several species are not very distinctive, often rod-like. With the following key, it is possible to identify males of all known species and females of most species (females of undescribed species of the montana complex are included). In most cases dissection of genitalia is needed, as well as examination of abdominal setal patches, bursal sclerites and hind wings of females.
