Etymology.

From the type locality.

Biology.

The species was collected between 450-1200 m in elevation, in transitional humid forest, rainforest, and montane rainforest. Nests were located in rotten logs and rotten twigs on the ground.

Comments.

Pheidole makirovana sp. nov. is most similar to P. curvistriata sp. nov. Major workers. Pheidole makirovana sp. nov. differs from P. curvistriata sp. nov. by pronotum, mesonotum, anepisternum, and katepisternum with smooth notches and outer hypostomal teeth wider than inner hypostomal teeth. Minor workers. Pheidole makirovana sp. nov. differs from P. curvistriata sp. nov. by rugae on upper part of frons curved outward and smooth mesosoma.
