The North American fauna of
Meigen was studied. Four new species are described (

), and three new synonymies are proposed:
(Huckett, 1966) (=

);
(Rondani, 1866) (=
(Rondani, 1871),
); and
(Aldrich, 1918) (=
Sorokina & Pont, 2015,
). An annotated checklist, DNA barcodes (when available), and keys for each sex of the 24 named species of North American
are provided. The utility of DNA barcodes for the identification of
species across a wide geographical range was explored using sequences from five countries. A match between morphology and DNA barcodes was found for 71% (22/31) of species studied (including three unnamed taxa). The remaining nine species clustered into two groups of taxa with very little interspecific variation within clusters (groups of two and seven species). Caution is advised against using DNA barcoding as the only determination tool for
material without prior knowledge of its limitations for certain species groups.
