Abstract
Abstract The New World Arhytodini currently consist of three genera: Caccoplectus Sharp with 36 species ranges from Arizona, USA, to Brazil; Rhytus Westwood ( = Arhytodes Reitter) with 11 species found from Argentina to Venezuela; and Caccoplectinus Chandler & Wolda with a single species from French Guiana. Caccoplectus was only recently recognized to be present in Panama (Chandler 1976; Chandler and Wolda 1986), with 24 species now recorded and 19 of these occurring on Barro Colorado Island. Since Caccoplectus was recently reviewed by Chandler and Wolda (1986), discussion of Panamanian Arhytodini will be confined to the following two genera: Rhytus is here recorded from Panama by the collection of three new species; Woldenka, new genus, with a single new species from Barro Colorado Island, is described. A· specimen of each species, except Rhytus bocatorenus new species, was cleared, disarticulated, and mounted on a slide for comparison of foveae and other structures. The single specimen of bocatorenus has the male genitalia cleared and stored in glycerine in a capsule pinned beneath the specimen. Holotypes are deposited in the Field Museum of Natural History. All measurements are given in millimetres.
