A taxonomic revision of the subfamily Tillinae Leach (Coleoptera, Cleridae) in the New World.

The subfamily Tillinae Leach is represented by 12 genera in the New World. In this study, eight of these genera are revised. A diagnosis and redescription of the species of Barr, Rifkind, Barr, Latreille, Barr, Wolcott & Chapin, Spinola, and Chapin are presented. Barr is designated as a junior synonym of Barr. One species, Chevrolat, is transferred to . The following species are redescribed: (Wolcott), Barr, (Schaeffer), Rifkind, Barr, Klug, (Spinola), Rifkind, (Knull), (Spinola), Wolcott, (Chevrolat), (Fall), Schaeffer, (Say), Chapin, and De Zayas. Transcriptions of the original descriptions of Barr, Van Dyke and (Chevrolat) are given. Gray, with approximately 130 described species, is excluded from this study due to the number of species involved. The genera Burke and Wolcott are also excluded here since these groups have been recently revised elsewhere. Collection data are provided for all species revised. Updated distribution maps are presented. Keys to New World genera and species are given and taxonomic characters of relevant importance are provided and discussed.
