摘要
The genus Microthremma is confined to Argentina and Chile, and has contained five species. Two new species, M. angulatum and M. patagonicum, both placed in the crassifimbriatum complex, and a third new species, M. lobatum, placed in the griseum complex, are described and figured. Also M. crassifimbriatum is redescribed and figured. A key to males, diagnostic characters, and distributional records is given for all eight species.
