In the collection of Museu de Zoologia, Universidade de São Paulo, São Paulo, there are specimens from Schrottky's collection which constitute the sintypes of some of the species of Anthidium that he described in 1910. Studying this genus, it is pertinent to designate the Lectotypes of these species, as follows: Anthidium cuzcoense Schrottky, 1910; Anthidium garleppi Schrottky, 1910; Anthidium nigerrimum Schrottky, 1910; Anthidium patagonicum Schrottky, 1910, and Anthidium peruvianum Schrottky, 1910. The lectotype of Anthidium kuscheli Moure, 1957, deposited in the collection of Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, is also here designated.
