Abstract
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.
