Subgenus Stenocellus Casey, 1914
Stenocellus Casey, 1914: 243. Type species: Trechus rupestris Say, 1823 designated by Lindroth (1968: 885). Etymology. From the Greek stenos (narrow) and the last two syllables of the generic name Bradycellus , alluding to the narrower body of these Bradycellus -related species (" distinguished at once from Bradycellus by their more slender elongate parallel ... form ") [masculine].
Diversity.
Thirty-four species in North America (33 species), Mexico (three species, one endemic to Guadalupe Island), and the Bahamas (one species).
Identification.
Casey (1914: 243-257) published a key to the species then known except Stenocellus nebulosus , Stenocellus nigriceps , and Stenocellus subcordatus . He subsequently described three new species (Casey 1924). Lindroth (1968, as rupestris, nigriceps, and tantillus groups) covered nine species. The subgenus is in need of a revision.
Faunistic Note.
According to Kataev and Matalin (in Kryzhanovskij et al. 1995: 135), the sole syntype (a badly damage ♂) of Stenolophus elongatus Motschulsky, 1860 in ZMMU, reported from the Kuril Islands, is a specimen of this subgenus. Since no species of Stenocellus are known from the Far East, they concluded that the specimen is mislabeled and probably originated from northwestern North America.
