RESUMO
We describe seven new Neotropical species of Tischeriidae: Astrotischeria dondavisi Stonis Diskus, sp. nov., A. bacchariphaga Diskus Stonis, sp. nov., A. guatemalica Diskus Stonis, sp. nov., A. sanjosei Stonis Diskus, sp. nov., A. truncata Diskus Stonis, sp. nov., Coptotriche parvisacculata Diskus Stonis, sp. nov. and C. carmencita Stonis Diskus, sp. nov. We report the discovery of Coptotriche Walsingham in South America and provide the following new host-plant records for the Neotropical Tischeriidae: Terminalia australis Cambess. (Combretaceae), Baccharis latifolia (Ruiz Pav.) Pers., and B. emarginata (Ruiz Pav.) Pers. (Asteraceae). We update the biology of Astrotischeria ochrimaculosa Diskus, Stonis Vargas with the discovery that Wissadula (Malvaceae) is a new, verified host plant. The new species are illustrated with photographs of the adults, male and, if available, female genitalia, and the leaf mines. We expect broader distributions of tisheriid species in South America inferred from known host-plant distributions.
