Rightmyer Division of Entomology, Natural History Museum, and Entomology Program, Department of Ecology and Evolutionary Biology, Snow Hall, 1460 Jayhawk Boulevard, University of Kansas, Lawrence, Kansas 66045-7523, USA — Abstract. The new genus Rhathymodes is proposed for Rhathymus acutiventris Friese [with its R. new synonym, fiiesei Ducke], and R. bertonii Schrottky; resulting in the new combinations: Rhathymodes acutiventris (Friese) and R. bertonii (Schrottky). A lectotype is newly designated for R. friesei. To accommodate the new genus, changes are suggested for a key to subfamilies and tribes of Apidae. The tribe Rhathymini and its two genera are characterized, as are the two species of Rhathymodes. The neotropical cleptoparasitic apine Engel (2001); equivalents are indicated in tribe Rhathymini consists of moderate brackets in keys and descriptions. The ab- sized to large (13-28 mm body length) breviations T and S are for metasomal ter- species superficially resembling vespid ga and sterna; T3, for example, is the third wasps, especially Polistes, or suggesting in metasomal tergum.
