BraZil. Three of these represent unnamed species and are described as new: Celaenorrhinus orneates Austin, Celaenorrhinus par SteinhauSeI' &Austin, and CelaeRorrhiRl/s aI/WeldOR SteinhauseI' &l·ustin. Themaleole salliais describedfOl'thefirsttime. Bothsexes ofall 8 speCIes (except female C. orneates) andtheir gemtaIiaare illustrated. Males of C. sauJa and C. orneates are similar to C. iao in lacking tibial tufts, modified thoracic scales, and abdominal pouches; C. autockton lacks tibial tufts and modified thoracic scales. This adds to the diversity ofsecondary sexual characters among New World Celaenorrhinus.
