Archilestris capnopterus is a large robber fly, with a body length ranging from 17 to 25 mm. The head is black, featuring a silvery-white pollinose face that is approximately one-fifth the width of the head, complemented by a white mystax and beard. The third antennal segment is black, characterized by a truncate apex and an apical spine. The thorax is dark chocolate-brown, marked with silvery-white and brownish pollinosity. The legs are predominantly black with black vestiture, but exhibit distinct whitish coloration on the basal two-thirds of the fore and middle first tarsal segments, the bases of the femora and tibiae, the entire hind metatarsus, and the basal two-thirds of the second hind tarsal segment. The abdomen is black, covered with recumbent black hairs on the dorsum and longer white hairs along the lateral margins.[2] These morphological traits are consistent with observations of the species in the TreeOfLife-200M dataset.[1]
Archilestris capnopterus is a forest-dwelling species found in southeastern and southern Brazil and Paraguay. It is typically encountered in shadowed forest trails, where it has been observed preying on Tipulidae.[2]
Within the genus Archilestris, A. capnopterus is considered closely related to A. geijskesi. Both species are thought to possess more primitive characters compared to other members of the genus, such as a narrow face and slender hind femora, which are approximately 10 times as long as they are broad.[2]
