Psilotus is an endemic Neotropical genus of Nitidulidae occurring from Mexico and Trinidad to Argentina, Bolivia, and southeastern Brazil. These dorsoventrally flattened beetles are typically found in subcortical habitats. The addition of Psilotus bicolor, new species, brings the total number of species to 11. A thorough description, diagnosis, and habitus photograph are provided for easy identification. Comments are given on male mandibular morphology, and new distribution records for P. atratus Reitter, P. carbonicus Erichson, P. cornutus (F), P. germaini Grouvelle, and P. ventralis Erichson are provided.
