Type material: Holotype male, BRAZIL: São Paulo State, Parque Estadual Intervales, sede de pesquisa, 16. viii. 2000, larvae taken on tree trunks, H. F. Mendes (MZUSP, slide mounted in Euparal). Paratypes: 2 males, as holotype (ZMBN). Diagnostic characters: The male imago can be separated from other members of the genus by having bare wing membrane; squama with a few setae; long costal extension; scalpellate acrostichals starting near antepronotum; long virga; nearly parallelsided anal point with blunt apex and weak lateral setae; and inferior volsella short and pointed triangular.
