Bousquet, Yves, 2012, Catalogue of Geadephaga (Coleoptera, Adephaga) of America, north of Mexico, ZooKeys 245, pp. 1-1722 : 725

Subgenus Neocalathus Ball and Negre, 1972

Neocalathus Ball and Nègre, 1972: 426. Type species: Carabus melanocephalus Linnaeus, 1758 by original designation. Etymology. From the Greek prefix neo - (new) and the generic name Calathus [q.v.] [masculine].

Diversity.

Forty-five species in North America (six species), Mexico (13 species), and the Palaearctic Region (27 species, no endemic species in eastern Asia).

Taxonomic Note.

Gañán and Novoa (2006) considered Neocalathus as a synonym of Amphyginus Haliday, 1841 (type species: Carabus piceus Marsham, 1802 (= Calathus rotundicollis Dejean, 1828)). If this approach is followed, then Amphyginus is the valid name for this subgenus (see Alonso-Zarazaga 2006).

Faunistic Note.

The record of Calathus ambigens Bates from Huachuca Mountains in southeastern Arizona (Schaeffer 1910: 394) is probably in error since the species is recorded only from Durango and Chihuahua in Mexico by Ball and Nègre (1972: 461-462).
