Atomosia sayii is a species of robber fly characterized by a compact, robust body form typical of the genus Atomosia. Based on observations from the TreeOfLife-200M dataset, the species exhibits a dark, often blackish, overall coloration. The body is covered in fine, dense pubescence, which can appear yellowish or golden, particularly on the thorax and legs, contributing to its common name, the "Yellow-legged Micropanther" [2]. The wings are typically clear or slightly smoky, and the legs are distinctively marked with lighter, yellowish-orange coloration, contrasting with the darker body. The eyes are large and prominent, occupying a significant portion of the head, as is characteristic of the family Asilidae.
Atomosia sayii was described by Charles Willison Johnson in 1903 [2]. Like other members of the family Asilidae, it is a predatory insect.
