Comments. This species corresponds to sp 52 in the cladograms of Miranda (2011).

Etymology. The specific epithet is a patronym honouring Dr. Ximo Mengual, colleague syrphidologist who collected some of the specimens, of this and other species, used in this study. The name is to be treated as a noun in the genitive case.
