Tetraponera allaborans -group: new synonymy of Malagasy species

The T. allaborans -group is represented in the Malagasy region by about 30 species (10 described), which form a single clade (Chomicki et al. 2015; Ward, unpubl.). This group will receive treatment in a forthcoming revision. Here synonymy is documented for five of the described species ( T. hysterica, T. longula, T. mandibularis, T. morondaviensis, and T. sahlbergii). With these synonymies established, the remaining valid names ( T. diana, T. exasciata, T. fictrix, T. perlonga, and T. rakotonis) are believed to represent bona fide species.
