A CLADISTIC-ANALYSIS OF THE SUBFAMILY PHILANTHINAE (HYMENOPTERA, SPHECIDAE)

The Philanthinae, as treated here, contains the eight valid genera Aph ilanthops Patton, Cerceris Latreille, Clypeadon Patton, Eucerceris Cre sson, Philanthinus Beaumont, Philanthus Fabricius, Pseudoscolia Radosz kowski and Trachypus Klug. Listropygia Bohart is synonymized with Clyp eadon, syn.n. The genera Eremiasphecium Kohl and Odontosphex Arnold ar e removed from the Philanthinae and regarded as genera incertae sedis within Sphecidae. Analysis of the genera of this redefined subfamily P hilanthinae finds two major clades whose monophyly is strongly support ed: (Philanthinus + (Philanthus + Trachypus)) [= Tribe Philanthini] an d (Pseudoscolia + (Cerceris + Eucerceris)) [= Tribe Cercerini]. There is some evidence for the monophyly of Clypeadon + Aphilanthops [= Trib e Aphilanthopini]. Cerceris and Philanthus are inferred to be paraphyl etic with respect to Eucerceris and Trachypus, respectively. Philanthi nus is removed from the tribe Aphilanthopini and placed in the tribe P hilanthini, and the monotypic tribe Pseudoscoliini is synonymized with Cercerini.
