A review of the flower fly genus Ornidia Lepeletier & Serville (Díptera: Syrphidae) with the description of a new species from Brazil

摘要

Ornidia Lepeletier & Serville is an endemic New World genus that now comprises five described species. The genus is reviewed and Ornidia therezinhae sp. n. is described and figured from Brazilian Amazon. A key to all species is provided. The family Syrphidae, commonly called flower flies or hover flies, has a worldwide distribution and consists of about 6,000 described species with representatives occurring in all zoogeographical regions (Thompson et al. 1976, Thompson 2008). The Neotropical region is by far the richest with more than 1,600 species belonging to 60 genera (Thompson 1999), but a large fraction of this fauna remains uncollected and undocumented.
