Genus Cyrtodesmus Gervais, 1847

Note: Loomis (1964: 34) synonymized Oncodesmus under Cyrtodesmus . Hoffman (1999: 510) argued to maintain the generic name Oncodesmus for the type species granosus. Golovatch (2001: 332) recognized that several species assinged to Cyrtodesmus are insufficiently known prohibiting unambiguous generic placement. The genus deserves a comprehensive revision.
