Large bodied flies, body length 5.9–8.4 mm, wing length 7.0– 9.4 mm; eyes holoptic; postpedicel with obtuse to rounded apex; dorsocentral and scutellar setae diminutive; scutellum rugose on posterior third; propleura without setae; rows of ventral spines present on fore and mid femora; well-developed setae on posterior surfaces of all femora, longer and denser on mid femora; hind tarsi enlarged and flattened; pterostigma present; basal third of wing usually brown infuscated (only slightly infuscated in some species and completely hyaline in others); crossvein r-m placed near basal third of cell dm; crossvein dm-m curved; vein M 2 absent; abdomen wide and oval, with inconspicuous pilosity, pruinose; tergite 1 narrow, without long lateral setae; tergite 2 with lateral setae as long as setae on tergite 1; male terminalia with tergite 6 and sternite 7 visible dorsally; syntergosternite 8 with membranous area (except in A. duckei Galinkin & Rafael ); epandrium swollen, partially visible dorsally on right side; surstyli symmetrical or subsymmetrical, fused or not with epandrium, with proximal, dorsal surface distinctively elevated; hypandrium invaginated at the fusion point with the subepandrial sclerite; membranous apodeme of the hypandrium/subepandrial sclerite present; phallic guide distinctly widened proximally; phallus single, apically swollen and membranous, usually with subapical protuberances; phallus with a paired process at base, usually large and surpassing posterior margin of hypandrium; sperm pump hemispherical; female ovipositor short and straight.

Distribution ( Fig. 184 ).
