Interpretive Summary: While many Leaf-tier moths are potential invasive threats to U.S. agriculture and natural resources, particularly species in the American tropics with close relatives in the contiguous United States, some can be used for the biological control of invasive plants. In order to determine pest moths from potentially beneficial moths their identities and the breadth of their diets must be accurately recorded. Here we describe three new genera and five new species of moth feeding on the invasive plant Brazilian peppertree, so the details of its biology can be accurately reported in subsequent research. We provide a hypothesis for how the new moth is related to known moths and discuss and illustrate diagnostic features that allow its identification by stakeholders. This information will be useful to scientists, action agency identifiers, and biocontrol laboratories
Technical Abstract: Recent efforts to discover insect biological control agents of the Brazilian peppertree, Schinus terebinthifolius, include three new genera, Tentamen Metz new genus, Longistrebula Metz new genus, and Tectosquamae Metz new genus, and three new species; Tentamen atrivirgulatum Metz new species, Longistrebula argalata Metz new species, Tectosquamae furvalata Metz new species, belonging to the subfamily Gelechiinae. An additional two species, Tectosquamae poguei Metz new species and Tectosquamae solisi Metz new species, from Paraguay are also described. We diagnose, describe, and illustrate the new taxa, and propose hypotheses for placement within the subfamily.
