| Formica accreta|
|At a Glance||• Polygynous|
This is a black species with the metasternal process poorly developed. The gena is without coarse punctures, although poorly defined, elongate punctures are located just anterior to the eyes. The scapes are usually longer than the head length. The anterior border of the clypeus is angulate, the eyes are large (maximum diameter 0.43 - 0.54 mm). The ventral surface of the head, posterior border, dorsum of the mesosoma and dorsum of the petiole are without erect hairs. The first gastral tergite has only 3 or 4 short (> 0.1 mm), blunt hairs. The dorsal surfaces of the head and mesosoma are weakly shining. (Mackay and Mackay 2002)
