Genus Bradycellus Erichson, 1837

Bradycellus Erichson, 1837: 64. Type species: Carabus collaris Paykull, 1798 (= Acupalpus caucasicus Chaudoir, 1846) designated by Andrewes (1935: 20). Etymology. From the Greek bradys (slow) and cello (to run), probably alluding to the slow pace of the adults in nature [masculine]. Note. As pointed out by Andrewes (1935: 20), the first valid type species designation for Bradycellus Erichson is that of Harpalus placidus Gyllenhal, 1827 as selected by Westwood (1838: 6). This species is currently included in Trichocellus Ganglbauer, 1892. In order to preserve stability, an application should be submitted to the Commission to suppress Westwood’s designation.

Diversity.

About 130 species (Lorenz 2005: 356-358) arrayed in ten subgenera: Atlantocellus Wrase and Jaeger (five species from the Canary and Madeira Islands), Bradycelloides Habu (one east Palaearctic species), Bradycellus s.str. (45 species), Catharellus (one species), Desbordesius Maindron (one east Palaearctic species), Liocellus (eight species), Lipalocellus (two species), Stenocellus (34 species), Tachycellus Morawitz (27 Palaearctic species from Asia with one species extending into the Oriental Region), and Triliarthrus (six species). The North American fauna is represented by 51 species (roughly 39% of the world fauna).

Taxonomic Note.

Noonan (1976: 21) also included Psychristus Andrewes (six species) and Nipponobradycellus Habu (four species) in this genus. In Lorenz (2005: 358), Nipponobradycellus is listed as a subgenus of the genus Psychristus .
