GENUS PLATYCHEIRUS Lepeletier & Serville

PLATYCHEIRUS Lepeletier & Serville 1828: 513 . Type-species: Syrphus scutatus Meigen, 1822 , by designation of Westwood, 1840: 137.

When describing huttoni (as milleri ) I noted that this species had all the essential characters of Platycheirus , sensu lato, except that male prolegs were not modified. Many other species are similarly characterized and the genus group name Eocheilosia Hull is associated with one of these species. Hence, I use this name for those species of Platycheirus with unmodified male prolegs. The determination of whether modified male prolegs is a primitive or derived trait must await a world revision of the genus Platycheirus and the identification of its sister-group. However, despite the phylogenetic status of Eocheilosia, the group is distinctive morphologically and zoogeographically. About a dozen more species are known and await description.

The female holotypes of fulvipes Miller and milleri Hull were examined and found to represent the same species.
