Abstract.The species ofApocephalus, subgenusMesophora, are revised and twenty‐eight species are recognized, including the following twenty‐two new to science: from the Nearctic RegionA. brunnipes, A. gemursus, A. pristinus, A. setialvusandA. unitarsus, and from the Neotropical RegionA. absentis, A. adustus, A. anfractus, A. angustistylus, A. bisetus, A. brevicercus, A. curtus, A. gracilis, A. hansoni, A. leptotarsus, A. longistylus, A. micrepelis, A. moraviensis, A. prolatus, A. trisetus, A. tritarsusandA. truncaticercus.Additionally, three species known only from female specimens are described but not formally named. A lectotype is designated forA. mortiferBorgmeier, and immature stages ofA. borealis, A. antennatusandA. mortiferare described. Unlike larvae of otherApocephalusspecies, all of which are parasites of ants (Hymenoptera: Formicidae), those ofMesophoraspecies are parasites of various other ho
