Distribution

Madagascar. There are two species of this group known only from their type localities: Pheidole ehazoara collected in Ehazoara Canyon in Toliara and P. makaensis described from Makay Mts. in Toliara. Pheidole fitarata is sympatric with P. avaratra and distribution of both taxa is limited to northernmost parts of the Sambirano rainforest and dry deciduous forest biomes in the Antsiranana prefecture. Pheidole rugofitarata is known from area spread between Belo and Antonibe.
