A new species and new subgenus of the Genus Elaphrus from North China, with cladistic analysis of taxa of the tribe Elaphrini (Coleoptera: Carabidae)

A new subgenus Sinoelaphrus new subgenus of Elaphrus is described based on a new species from north China, E. angulonotus new species (type locality: Beijing, Haidian, Yangtaishan, 205m). The new species is different from other members of the genus in having a prominent lateral angle on the pronotum and one seta on each angle.
