Based on observations of preserved specimens, Acrochaeta adusta exhibits characteristic features of the family Stratiomyidae. The body is slender, with a distinct, elongated abdomen. The thorax displays a patterned surface, and the wings are typically clear or lightly tinted. The antennae are relatively long, a trait that has historically led to taxonomic confusion with the genus Merosargus [2]. These morphological observations are consistent with specimens found in the TreeOfLife-200M dataset [1].
Acrochaeta adusta was described by Lindner in 1949 [3]. The genus Acrochaeta (Diptera: Stratiomyidae: Sarginae) has historically been difficult to delimit, with previous diagnoses often relying on plesiomorphies, which caused confusion with the genus Merosargus [2].
A comprehensive taxonomic revision and cladistic analysis have since been conducted to better define Acrochaeta from a phylogenetic perspective. This study supported the monophyly of the genus based on specific characters of the head, thorax, and abdomen, and identified an inner clade within the genus characterized by male genitalia features [2].
