A new inquiline ant (Hymenoptera: Formicidae) in Cataglyphis and its phylogenetic relationship

Cataglyphis hannae, a new workerless, putatively inquiline ant species is described and its phylogenetic relationships and biology discussed. C. hannae was collected in two different nests of C. bicolor and, based on its smaller size and the delayed production of sexuals in comparison to its host, an inquiline life style is inferred. If correct, this would be the first social parasite within Cataglyphis. Cladistic analysis indicates an independent origin of the inquiline with subsequent invasion of its host.
