Abstract

Eight species of Celaenorrhinus (Hesperiidae: Pyrginae) occur near Cacaulhdia in central Rondonia, Brazil. Three of these represent unnamed species and are described as new: Celaenorrhinus orneates Austin, Celaenorrhinus par Steinhauser & Austin, and Celaenorrhinus autochton Steinhauser & Austin. The male of C. saviais described for the first time. Both sexes of all 8 species (except female C. orneates) and their genitalia are illustrated. Males of C. savia and C. orneates are similar to C. jao in lacking tibial tufts, modified thoracic scales, and abdominal pouches; C. autochton lacks tibial tufts and modified thoracic scales. This adds to the diversity of secondary sexual characters among New World Celaenorrhinus. The following taxa, treated by Evans (1952) as subspecies, are raised to specific rank: C. shema disjunctus Bell, 1940; C. similis stola Evans, 1952; C. similis approximatus Williams & Bell, 1940; and C. similis bifurcus Bell, 1934.
