Pegomya centaureae Hering, 1957; Pont & Ackland (2009a) discuss the confusing nomenclature.
The Fauna Europaea (2011) states that Hennig originally placed his species in the genus Pegohylemyia (=Botanophila); therefore the species is listed there within Botanophila. Actually, Hennig described the species as Pegomya centaureae. (Thanks to Charles Godfray for pointing this out to me).
