Abstract
Bolboceras bopdevense Kalawate & Hillert, new species and Bolboceras trimbakense Kalawate & Hillert, new species, both classified in the Bolboceras nigricans Westwood, 1848 species group are described from India. Illustrations and comparison with known members of the B. nigricans species group are given. The new described species are included in an updated identification key of the species group. Finally, known localities of this species group are mapped. For the Oriental and east Palearctic regions, all known localities of the genus Bolboceras Kirby, 1819 are listed, and associated coordinates are given.
