© Her Majesty the Queen in Right of Canada 2017 Melaphis rhois Fitch (Hemiptera: Aphididae) has been considered the only North American representative of the aphid subtribe Melaphidina. Molecular and morphometric analysis indicates that there are at least three sympatric cryptic melaphidine species in North America. Melaphis asafitchi new species is described and M. rhois is redefined and a neotype designated. The name Melaphis minuta Baker cannot be assigned to either of these species. Details of the life cycles of Melaphis Walsh species, including the existence of ovoviviparity in sexual females, is discussed.
