Subgenus Reductonebria Shilenkov, 1975

Reductonebria Shilenkov, 1975: 834. Type species: Nebria ochotica Sahlberg, 1844 by original designation. Etymology. From the Latin reducto (bring back, reduce) and the generic name Nebria [q.v.], possibly alluding to the absence of mid-lateral setae on the pronotum of the species [feminine].

Diversity.

Twenty-eight species in North America (24 species) and Siberia and the Far East (four species).

Faunistic Note.

Nebria carbonaria Eschscholtz was reported from Alaska by Horn (1870b: 104) and LeConte (1878a: 479) and there is a specimen of this species in the LeConte collection labeled "Ins. S. Pauli," one of the Pribilof Islands in Alaska. Lindroth (1961a: 74) believes the specimen is probably mislabeled since no other specimens of the species have been found on the island despite extensive search. The species was described from specimens collected "in Kamtschatka, bei St. Peter und Paul" which, according to Lindroth (1961a: 74), refers to the town of Petropavlovsk in Kamtschatka. Until recent specimens are collected on this continent, the species is not listed as a North American resident.
