The subfamily Cercobarconinae is synonymized with the Trachypetinae, the constituent genera (Trachypetus Guerin de Meneville, Megalohelcon Turner and Cercobarcon Tobias) are rediagnosed and the species are revised and redescribed. Rhamphobarcon Tobias is synonymized with Megalohelcon Turner, R.mosaicus Tobias is synonymized with M.torresensis Turner, M.uptoni Tobias is synonymized with M.ichneumonoides Tobias, and four species are newly described: M.mouldsi, C.bilobatus, C.grossi and C.niger. Relationships within the subfamily are discussed, as are those of the Trachypetinae to other braconid subfamilies. Comments on the biology and distribution of species are provided, along with an illustrated key to genera and species.
