The egg parasitoid Telenomus remus (Hymenoptera: Scelionidae) has been investigated for classical and applied biological control of noctuid pests, especially Spodoptera (Lepidoptera: Noctuidae) species. Although T. remus was introduced into Brazil over three decades ago for classical biological control of S. frugiperda, this wasp has not been recorded as established in corn or soybean crops. We used an integrative approach to identify T. remus, combining a taxonomic key based on the male genitalia with DNA barcoding, using a cytochrome c oxidase subunit I mitochondrial gene fragment. This is the first report of natural parasitism of T. remus on S. frugiperda and S. cosmioides eggs at two locations in Brazil. We also confirmed that the T. remus lineage in Brazil derives from a strain in Venezuela (originally from Papua New Guinea and introduced into the Americas, Africa, and Asia). The occurrence of T. remus parasitizing S. frugiperda and S. cosmioides eggs in field conditions, not associated with inundative releases, suggests that the species has managed to establish itself in the field in Brazil. This opens possibilities for future biological control programs, since T. remus shows good potential for mass rearing and egg parasitism of important agricultural pests such as Spodoptera species.

Paridris in the New World is revised (Hymenoptera: Platygastridae). Fifteen species are described, of which 13 are new. Paridris aenea (Ashmead) (Mexico (Tamaulipas) and West Indies south to Bolivia and southern Brazil (Rio de Janeiro state)), P. armata Talamas, sp. n. (Venezuela), P. convexa Talamas, sp. n. (Costa Rica, Panama), P. dnophos Talamas, sp. n. (Mexico (Vera Cruz) south to Bolivia and central Brazil (Goiás)), P. gongylos Talamas & Masner, sp. n. (United States: Appalachian Mountains of Virginia, Tennessee, South Carolina), P. gorn Talamas & Masner, sp. n. (United States: Ohio south to Alabama, Georgia), P. invicta Talamas & Masner, sp. n. (Brazil: São Paulo), P. isabelicae Talamas & Masner, sp. n. (Cuba, Dominican Republic), P. lemete Talamas & Masner, sp. n. (Puerto Rico), P. minor Talamas, sp. n. (Cuba), P. nayakorum Talamas, sp. n. (Costa Rica), P. pallipes (Ashmead) (southeastern Canada, United States south to Costa Rica, also Brazil (São Paulo), P. psydrax Talamas & Masner, sp. n. (Argentina, Mexico, Paraguay, United States, Venezuela), P. saurotos Talamas, sp. n. (Jamaica), P. soucouyant Talamas & Masner, sp. n. (Colombia, Trinidad and Tobago, Venezuela). Paridris brevipennis Fouts, P. laeviceps (Ashmead), and P. nigricornis (Fouts) are treated as junior synonyms of P. pallipes; Paridris opaca is transferred to Probaryconus. Lectotypes are designated for Idris aenea Ashmead and Caloteleia aenea Ashmead. [ABSTRACT FROM AUTHOR]
