A revision of male ants of the Malagasy region (Hymenoptera: Formicidae): Key to genera of the subfamily Proceratiinae

Abstract

Male-based keys to the ant genera of Proceratiinae in the Malagasy region (Madagascar, Mauritius, Reunion, Comoros, and Seychelles) are presented. All three extant genera known from the Malagasy region, Discothyrea, Probolomyrmex, and Proceratium, and an undescribed taxon, PRm01 from Seychelles, are included. Diagnoses and remarks on the subfamily Proceratiinae and its four genera, and a character table for these genera, are given. The males of all genera are illustrated.
