Abstract
In the present paper the Oriental carabid genus Actenoncus Chaudoir, 1871 is redefined and reviewed for the first time. The absence of a median tooth on the right mandible is no longer considered a diagnostic character of this genus. Orthogonius foersteri Andrewes, 1931 is transferred into Actenoncus (new combination) and a new species is described from Indonesia, A. wallacei, new species. A key to all known species of Actenoncus is also provided.References
