Fore wings with 4 cells Rs; cell R open; vein Sc absent; vein 2r–m present; vein B of fore wing joins vein R well before (longer than vein Sc) junction point of vein M; cell 2A absent. Petiole of cell A of hind wing about 2.0 times its width. Claws simple.All tibiae without preapical spurs. The colour often yellow with black and without metallic sheen.

The genus is distributed in the Palaearctic, Nearctic and Oriental regions. Number of species: World — 55; Palaearctic — 50. The life history of Aprosthema tardum (Klug, 1814) was investigated by Liston et al. [2018]. The most complete key to the genus for the Palaearctic region was compiled by Gussakovskij [1935], but it is now considerably out of date and requires substantial revision and correction. Key to Chinese species see in Wu et al. [2021], European — in Lacourt [2020].
