Résumé

Colosmittia brasileira sp. n. from São Paulo state, Brazil, is described and illustrated based on a male imago. The genus Colosmittia Andersen & Sæther was described based on a single species, C. clavata Andersen & Sæther, from the West Usambara Mountains, Tanzania, East Africa. The discovery of the new species shows that Colosmittia has an Afro-Brazilian distribution pattern.

Résumé

Irisobrillia longicosta Oliver, originally described from Venezuela, is taken in Malaise traps close to small rivers in the state of Santa Catarina in south Brazil. The specimens from Brazil are small compared to the types from Venezuela, and are thus described in some detail. Irisobrillia is the only genus of the primitive Orthocladiinae close to the genus Brillia Kieffer occurring in the Neotropical region.
