Etymology. Patronym for Dr. Sixto Coscarón, Universidad Nacional de La Plata (Argentina), friend and Neotropical specialist in the family Tabanidae.
Comments. C. coscaroni n. sp. is easily distinguished from other species of Caenopangonia by their conspicuous golden pilosity. Except to C. hirtipalpis which is very close, but the following characters allow differentiation: the color of body; antenna black with golden hairs; palpus black with golden hairs, with apex of second segment clavate; apex of gonostylus truncate with two small pointed lobes; anterior margins of epandrium pointed and slightly curved.
