This page represents the following TreeOfLife-200M taxonomic path.[1]
Amblypsilopus flies are characterized by their slender, often metallic-colored bodies, typical of the subfamily Sciapodinae. Observations from the TreeOfLife-200M dataset reveal several consistent morphological traits: the legs are generally elongate and slender, and the wings are often clear or lightly tinted with distinct venation patterns, including a characteristic bend in the M1 vein.[1]
The genus Amblypsilopus is characterized by a subrectangular postpedicel with a dorsal or dorsoapical arista-like stylus.[2] Wing venation typically features a vein M1 with an elbow-shaped bend, where the basal part forms an acute or right angle with M1+2; the crossvein dm-m is straight or slightly convex.[2] Legs are generally elongate with weak major setae, and the anterior preapical seta is absent on the femora.[2] Males consistently exhibit secondary sexual characters (MSSC), such as modified or ornamented fore tarsi, and the cercus lacks a hook-shaped or articulated basoventral lobe.[2]
Amblypsilopus is a highly diverse, globally distributed genus with approximately 360 species.[2] The genus is considered poorly defined and potentially polyphyletic.[2] Several species groups have been identified, including the A. abruptus group, the A. mufindiensis group, and the A. fasciatus group.[2]
