Acrosathe is a genus of stiletto flies within the family Therevidae. It is recognized as a distinct genus, specifically placed within the subfamily Therevinae in the Nearctic region [2]. The genus was established by Irwin and Lyneborg in 1981 [3, 6].
Based on observations of Acrosathe annulata from the TreeOfLife-200M dataset, these flies exhibit a slender, elongated body form characteristic of many stiletto flies [1]. They typically display a metallic or greyish coloration, often with fine, silvery-white pubescence or hair-like structures covering parts of the thorax and abdomen [1]. The wings are generally clear or slightly smoky, and the legs are slender [1].
The classification of Acrosathe is part of a broader systematic revision of Nearctic Therevidae that emphasizes the use of synapomorphies to establish a robust generic framework [2]. Diagnostic treatments for the genus often incorporate detailed examinations of male terminalia to assist in species-level identification [2].
