Abstract
Scent producing organs involving parts of the thorax as well as of the abdomen in males of Calaenorrhinus and some related genera are described. The unique character of abdominal pouches with scent hairs is applied to delimit the genus Celaenorrhinus Hübner, 1819, the only pantropical genus of the Hesperiidae. As a consequence, the genera Orneates Godman and Salvin, 1894, and Charmion de Nicéville, 1894, are placed in synonymy. Two species without secondary sexual characters are also considered to belong to Celaenorrhinus, viz., Plesioneura aurivittata Moore, 1865, and Plesioneura jao Mabille, 1889, the latter being placed in Celaenorrhinus for the first time. The evolution of the described scent organs is discussed in relation to their geographic distribution.Keywords
