Cheilosia scanica Ringdahl, 1937 and Cheilosia morio auct.

Two different species are mixed under the name C. morio (Zetterstedt) . The correct names of both remain to be established (Speight 2020). Here we use the name C. scanica Ringdahl for the species with a hairy face and the name C. morio sensu Becker for the species with a bare face. In some cases, it was impossible to access old material and literature on C. morio . Therefore, we included data from verified material and recent records only.
