A phylogenetic tree of the Iberian Aphaenogaster species - except for A. splendida (Roger) - and a key to the worker caste of all Iberian Aphaenogaster species are proposed. The position of A. striativentris Forel and A. cardenai Espadaler is discussed, stating the possibility that this second species may belong to a new, undescribed genus. Aphaenogaster ulibeli n. sp. is described from the Iberian Peninsula. Its closest relatives are A. gibbosa (Latreille) and A. striativentris. Its habitat seems to be restricted to caducifolia forests in the Western Central Massif.

The first ant-Laboulbenial interaction in Africa is recorded. The fungus Laboulbenia camponoti Batra was detected over the body of workers Camponotus oasium Forel collected in Senegal. This is a huge range extension of its Eurasian previously known distribution. We present the updated global database for L. camponoti.

One Laboulbenia species is added to the checklist of Italian fungi. Laboulbenia camponoti was detected on the ant Camponotus aethiops. Additionally, L. formicarum was found on a new host (Lasius niger) in France. An updated map of world distribution for the two Laboulbenia is presented. Based on present knowledge, L. camponoti shows a much higher structural and phylogenetic host specificity than L. formicarum.

A list of morphological characters to separate Iberoformica and Formica (Serviformica) (F. fusca species group) is provided. Sexual forms of Formica gerardi Bondroit are described based on Iberian material and reinstated into the subgenus Serviformica based on genetic data and morphological characters. The status of †F.horrida Wheeler, 1915 is assessed.
