Description
Summary:Torymus evansi Grissell, new species, is described, illustrated, and compared to other Nearctic species of the genus. Morphologically it is intermediate between the varians and tubicola species groups. Torymus evansi is associated with rearings of Dactylopius sp. (Hemiptera: Dactylopiidae) on Opuntia sp. (Cactaceae), and although its true host remains unknown, the association with this host-complex is unique for the genus.
