Cheilosia (Nephocheila) primaria Barkalov & Ståhls nomen nov.

Barkalov & Cheng (2004) described Cheilosia (Nephocheila) prima Barkalov & Cheng from China. A species of Cheilosia with the same name was however described by Hunter in 1896 from North America. Thereby the name of Barkalov & Cheng is a junior homonym of Hunter’s name. For the Chinese species we are proposing the new name Cheilosia (Nephocheila) primaria Barkalov & Ståhls nomen nov.
