Aedes (Fredwardsius) is a subgenus of the genus Aedes with distribution in southern Europe, southern Asia, and Africa. The subgenus was erected in 2000 after a comparison of specimens of Aedes vittatus with all other recognized genera and subgenera in the mosquito tribe Aedini indicated that the species had sufficiently unusual and unique morphological and other features of subgeneric rank significance to merit stand-alone status. Aedes vittatus was established as the type species, and is currently (2016) the only species in the subgenus, making Fredwardsius a monotypic taxon.
