Toxomerus immaculatus (Macquart, 1842) comb. nov.

Syrphus immaculatus Macquart, 1842: 158 . Type-locality: Brazil or Chile [T ♀ MNHN].

Ocyptamus immaculatus . Thompson et al. (1976: 20).

Comments. The type specimen shows typical abdominal markings of Toxomerus species and should be allocated therein. The illustrated type specimen in Macquart (1842: plate 17: fig. 1) clearly shows that it is a Toxomerus species.
