Diversity.

About 70 species (Lorenz 2005: 266-268) in the Nearctic (12 species, of which five extend into northern Mexico or Cuba) and Palaearctic (about 60 species) Regions.

Identification.

Chaudoir (1876c) reviewed the species but his work is outdated. Lindroth’s (1966) monograph covers seven of the 12 North American species.
