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complete key to the genus for the Palaearctic region was compiled by Gussakovskij [1935], but it is now considerably out of date and requires substantial revision and correction.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].
