The taxonomy of the American doryctine genus Callihormius is revised. Four Nearctic species are redescribed, including the type species of the genus (C. bifasciatus Ashmead, 1900, C. stigmatus Marsh, 1966, C. texanus Marsh, 1966 and C. werneri Marsh, 1966). Four Neotropical species are also described: C. circumlitoris sp. nov., C. franciscomartoi sp. nov., C. palagannensis sp. nov. and C. tayronensis sp. nov. Callihormius longicaudatus (Nettleton, 1938) is considered as "incertae sedis". A taxonomie key for the 13 currently recognised species of Callihormius is provided.
