Genus Nippononebria Ueno, 1955

Nippononebria Uéno, 1955: 49. Type species: Nebria pusilla Uéno, 1955 by original designation. Etymology. From the English nippon (a Japanese name for Japan) and the generic name Nebria [q.v.], alluding to the country where these Nebria -like species known to Uéno lived [feminine].

Diversity.

Seven species in western North America (three species), Japan (three species), and Jilin Province in China (one species) arrayed in two subgenera: Nippononebria s.str. for the Japanese and Chinese species and Vancouveria for the Nearctic ones.

Taxonomic Note.

Kavanaugh (1995, 1996) regarded Nippononebria as the sister-group to Leistus while Ledoux and Roux (2005) listed Nippononebria and Vancouveria as subgenera of Nebria and suggested they form the sister-group to { Eonebria Semenov and Znojko + Sadonebria Ledoux and Roux}, a complex of 60 Palaearctic species. Because the North American students are used to Kavanaugh’s approach, the taxon is retained here as a distinct genus.
