C o m m e n t: The above material was compared with the types. According to COIFFAIT (1984), A. curtulus is distributed in Sardinia and Corsica, but personal observations suggest that the species is endemic to Sardinia and previous records from Corsica are based on misidentifications. The specimens collected to the north of Orotelli were collected from nests of Tetramorium sp., whereas the remaining material was found under stones without ants, suggesting that this species is a facultative inhabitant of Tetramorium nests.
