oa Journal of the Entomological Society of Southern Africa - The Genus Hagensia Forel (Formicidae)
This genus was originally erected by Forel (1901) as a subgenus of Megaponera Mayr, and distinguished from that genus mainly by the absence of a carina on the cheeks, and by the marginate pronotum and the pointed and trenchant node of the petiole. Emery (1911) attached the subgenus to Euponera, but neither Emery nor Forel noticed the groove on the mandibles, and since in addition to these characters the claws are toothed in the ? and ?, I raised Hagensia to generic rank (1926).
