Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 111 1960 Number 3429 A REVISION OF THE GENUS OGCODES LATREILLE WITH PARTICULAR REFERENCE TO SPECIES OF THE WESTERN HEMISPHERE By Evert I. Schlinger^ Introduction The cosmopolitan Ogcodes is the largest genus of the acrocerid or spider-parasite family. As the most highly evolved member of the subfamily Acrocerinae, I place it in the same general line of develop-ment as Holops Philippi, Villalus Cole, Thersitomyia Hunter, and a new South African genus.^ Ogcodes is most closely associated with the latter two genera . The Ogcodes species have never been treated from a world point of view, and this probably accounts for the considerable confusion that exists in the literature. However, several large regional works have been published that were found useful: Cole (1919, Nearctic), Brunetti (192G, miscellaneous species of the world, mostly from Africa and Australia), Pleske (1930, Palaearctic), Sack (1936. Palaearctic), and Sabrosky (1944, 1948, Nearctic). Up to this time 97 specific names have been applied to species and subspecies of this genus. Of these, 19 were considered synonyms, hence 78 species were assumed valid. With the description of 14 new species and the addition of one new name while finding onl}^ five new synonyms, 1 Department of Biological Control, University of California, Riverside, Calif. • This new genus, along with other new species and genera, is being described in forthcoming papers by the author. 227
