Abstract

The male of Paradossenus pulcher Sierwald, 1993 and a new species, P. macuxi, from Roraima, Northern Brazil are described and illustrated for the first time. The monotypic genus Magnichela Silva & Lise, 2006 is a junior synonym of Paradossenus F.O. Pickard-Cambridge, 1903. Paradossenus amazonensis Carico & Silva, 2010 is a junior synonym of Magnichela santaremensis Silva & Lise, 2006 (type species). New data on the Brazilian distributions of Paradossenus acanthocymbium Carico & Silva, 2010, P. tocantins Carico & Silva, 2010 and P. pozo Carico & Silva, 2010 are presented.
