Stenocorse (Braconidae) is a doryctine wasp genus widely distributed from southern USA to central Argentina, and it has been reported to be ectoparasitoid of over 60 bruchine (Coleoptera: Chrysomelidae) species. The genus currently contains a single described species, S. bruchivora (Crawford), though recent molecular and morphological evidence revealed that it is actually composed of various undescribed species. Here we redescribe S. bruchivora (Crawford) and describe five new species from various geographic regions along the Neotropics (S. atlanticussp. nov., S. maesoi sp. nov., S. pacificus sp. nov., S. rosabricenae sp. nov., S. sudamericanus sp. nov.) We could not morphologically distinguish S. atlanticus sp. nov. from S. pacificus sp. nov., though they can be consistently delimited both geographically and with mitochondrial and nuclear DNA sequence data. We include information about the host plant legumes where the recognised species of Stenocorse and their associated bruchines were reared. A key to the recognised species of Stenocorse is provided.
