Vol. 13(1), 2004, pp. 1-12 The Cleptoparasitic Bee Tribe Rhathymini (Hymenoptera: Apidae): Description of a New Genus and a Tribal Review Michael S. Engel, Charles D. Michener, and Molly G. 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.
