Type genus: Patrobus Dejean, 1821. Diversity. Northern Hemisphere, with about 215 species arrayed in four subtribes following Zamotajlov (2002): Deltomerina (about 115 species), Deltomerodina (13 species in the genus Deltomerodes Deuve), Patrobina (about 80 species), and Platidiolina (five species). The North American fauna is represented by 13 species (roughly 6.2 % of the world fauna). Identification. Darlington (1938) and Lindroth (1961a) reviewed the North American species and provided keys for their identification. Subsequently to Lindroth's work, one species ( Patrobus septentrionis ) was shown to consist of two distinct forms by Zamotajlov (2003c).
