Revision of theOmophron (Phrator) ‘vittulatum’ species group (Coleoptera: Carabidae)

Review of the Omophron (Phrator) ‘vittulatum’ group led to an increase in the number of known species to four – Omophron (Phrator) vittulatum Fairmaire, 1894, Omophron (Phrator) schoutedeni Deleve, 1924, Omophron (Phrator) alluaudi Dupuis, 1913 stat. nov., and Omophron (Phrator) barsevskisi sp.n. One species was newly described: Omophron (Phrator) barsevskisi n. sp. The new species differs from other species of this group by a smaller size, rounded shape of elytra, and almost smooth elytral striae. Omophron (Phrator) alluaudi Dup. is recognized as a valid species. A key to the species is provided. Redescription, habitus illustrations, and distribution maps are provided for all species.
