In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with simply two wings were brought together under the name Diptera.
Ortalis is an historic genus of Ulidiid or picture-winged flies, first described by Fallén in 1810. It served as the type genus for the family Ulidiidae, which was called Ortalidae at the time. In 1932, it was pointed out by Adlrich that the name Ortalis was preoccupied by a genus of birds which had been named by Merrem in 1786. The name of the fly family was therefore revised, with some authors calling it Otitidae until Ulidiidae was settled on as standard. The genus itself was found to be paraphyletic, and all of its species have been reassigned to other genera, some in the Ulidiidae, and some in other Tephritoid families. In the following list, the species are organized according to the families and genera to which they have been reassigned.
