The taxonomic status of the nine species of the mostly Neotropical genus Macrocerides Borgmeier is reviewed after the holotypes of seven species are examined. Macrocerides anacleti Borgmeier, M. brevicornis Borgmeier, and M. luteus Borgmeier are transferred to Myriophora Brown (new combinations). Macrocerides neivai Borgmeier is transferred to Apocephalus (new combination), creating a homonym with Apocephalus neivai Borgmeier for which the replacement name A. elizaldae is proposed. The African Macrocerides leydheckeri Schmitz is placed in a new genus, Macrocerophora. Tauricornus, a new subgenus of Macrocerides, is proposed for a monophyletic group that includes M. (T.) abaristalis Borgmeier, M. (T). attophilus Disney, and two new species, M. (T.) taurocephalus from southern Texas, United States of America, and M. (T.) borkenti from Costa Rica to northern South America.
