Taxonomic history
The has undergone significant taxonomic revision. Five African were transferred to the genus Asthenotricha. The authorship is sometimes cited as Guenée, 1841 in older literature, though Hübner, 1825 has priority.
Species diversity
Over 60 are currently recognized, with new species continuing to be described from Asia, particularly by Japanese entomologist Hiroshi Inoue who described numerous species in the 1980s and 1990s.
