The fossil shows a dark brown body with lighter antennae, mandibles, and legs, and key features include a rectangular head longer than wide, small eyes near the clypeus, and short antenna scapes that do not reach the head's posterior margin . This species extends the known temporal range of the genus Protazteca into the mid-Eocene period .
