Based on observations of museum specimens, Alyssomyia species exhibit a robust, typical asilid body form. Key morphological traits include a sessile third antennal segment, which is a diagnostic feature distinguishing the genus from related taxa such as Hypenetes[2]. The wings are characterized by a closed fourth posterior cell[2]. Specimens observed in the TreeOfLife-200M dataset show a dense, setose appearance typical of the family, with distinct thoracic and abdominal patterning[1].
The genus Alyssomyia was established by Hull in 1962, with Clavator brevicornis Philippi designated as the type species[2]. It is classified within the tribe Stenopogonini[2].
The genus includes several species, such as Alyssomyia brevicornis, Alyssomyia nigribarbis, Alyssomyia rubricornis, and Alyssomyia keiseri[2]. Alyssomyia keiseri, described from Chile, is noted for its smaller size, golden pollen, and wings that are milky-white on the basal half in males[2].
