This key to queens is based on: Boer, P. 2013. Revision of the European ants of the Aphaenogaster testaceopilosa-group (Hymenoptera: Formicidae). Tijdschrift voor Entomologie 156, 57–93. PDF

Identifications should be preferably based on several specimens from the same colony, if possible of all three castes. Gynes of Aphaenogaster balcanicoides, Aphaenogaster karpathica and Aphaenogaster spinosa are unknown.
