Types. Holotype male and allotype female from BRAZIL: Belo Horizonte: Pampulha, Universidade Federal de Minas Gerais campus, 19°52' S, 43°58' W, 830 m, 2.vi.1996, Malaise trap, J.C.R. Fontenelle. Paratype: 1 female, topotypic, collected with the types. Holotype and allotype in MNRJ, paratype female in BPBM.

Etymology. The specific epithet derives from the Hawaiian “ kake ” = “Jack”; and is named for my mentor in bee fly studies, Jack Hall.

Remarks. One of the paratype females is darker than the holotype and allotype, but otherwise fits in all the salient characters that distinguish the species.

Distribution. Known only from the type locality in Brazil.
