We describe seven new Neotropical species of Tischeriidae: Astrotischeria dondavisi Stonis Diškus, sp. nov., A. bacchariphaga Diškus Stonis, sp. nov., A. guatemalica Diškus Stonis, sp. nov., A. sanjosei Stonis Diškus, sp. nov., A. truncata Diškus Stonis, sp. nov., Coptotriche parvisacculata Diškus Stonis, sp. nov. and C. carmencita Stonis Diškus, 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 Diškus, 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.
