This page represents the following TreeOfLife-200M taxonomic path.[1]
Members of the genus Achias are characterized by their distinct morphology, often featuring elongated, stalk-like projections on the sides of the head that support the eyes, a trait commonly referred to as "eyestalks." Observations from the TreeOfLife-200M dataset[1] reveal that these flies typically possess a robust body structure with patterned wings, often displaying dark markings or bands. The coloration of the body can vary, with many specimens exhibiting shades of brown, black, or metallic hues. The legs are generally well-developed, and the overall form is consistent with other members of the family Platystomatidae.
