E-mail:[email protected] Abstract: Fourteen species ofNeoclytus Thomson,l860 occur in Argentina: N. armaticollis Zajciw, N. aulai Bruch, N. centurio (Chevrolat),N. curvatus (Germ.)N. delicatus (Gounelle),N. famelicus (Burmeister),N. guianensis (Laporte &Gory), N. mulleri Fuchs, N. patagonicus (Bruch)comb. nov., N. pusillus (Laporte &Gory), N. rufus (Olivier),N. sobrinus (Laporte &Gory),N, stillatus Aurivillius (=N.parumnotatus Zajciw syn. nov. )and N. ypsilon (Chevrolat). N. armaticollis, N. delicatus and N. stillatus are new records for Argentina. The geographical distribution in Argentina and a key for species are given. Key Words: Argentina, Coleoptera, Cerambycidae, Neoclytus. Introduction ical distribution in Argentina and a key for species are also given. The worst obstacle for the revision of Neoclytus concerns the scarcity of specimens of this genus in Materials and Methods entomological collections. Many of its species are only known through type specimens (N. armaticol- Collections examined: AM: Antonio Martinez, lis, N. stillatus, and N. mulleri), and some species Rosario de Lerma, Salta; B: Carlos Bruch (MACN); are even known from a single individual (Neoclytus BURM: Hermann Burmeister (MACN); E: Entomo- aulai and N. patagonicus).
