There are few records for Telenomus dilophonotae Cameron, 1913 (Hymenoptera, Scelionidae) from South America. In Brazil, the first occurrence was reported in Bahia in rubber crops, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. - Arg., there parasitizing eggs of Erinnyis ello Linnaeus, 1758 (Lepidoptera, Sphingidae). It was also found parasitizing the same host in cassava, Manihot esculenta Crantz (Euphorbiaceae). This is the first record of occurrence of T. dilophonotae in the state of Paraná, parasitizing eggs of E. ello in areas of cassava production in the western region of Paraná, this being the southernmost record of the species. Here, photographs, the first sequence of DNA barcode of this species of parasitoid wasp, and a distribution map are provided.
