The Neoneura are a clade containing the majority of flies except for the basal tipulomorphs. They are characterised by having vein 1A distally reduced and not reaching the margin of the wing, and the arolium replaced by an empodium (Blagoderov et al. 2002). Basal lineages in the Neoneura include the Ptychopteridae, phantom crane flies, a group of long-legged flies with aquatic larvae found mostly in cooler regions. Ptychopterids are distinguished from other flies by the presence of a basal appendage on the halter, the prehalter. Three genera of ptychopterids are recognised worldwide: members of the genus Ptychoptera have thirteen segments in the antennal flagellum and a branched M vein in the wing whereas Bittacomopha and Bittacomorphella (together forming the Bittacomorphinae) have an eighteen- or nineteen-segmented flagellum and unbranched M vein. Bittacomorphella possess macrotrichia in the distal radial and medial cells of the wing, whereas Bittacomorpha lack such macrotrichia and have the first tarsomeres of all legs dilated (Alexander 1981).

A molecular analysis of fly phlogeny by Wiegmann et al. (2011) separated a basal division between clades containing the Ptychopteridae, Psychodomorpha and Culicomorpha on one side and Perissomatidae, Bibionomorpha and Brachycera on the other. The latter clade is known as the Neodiptera and is also united by features of the neck region sclerites and musculature. The Perissomatidae are a family of small flies found in Australia and South America that have the eyes completely divided into separate dorsal and ventral components. The Brachycera are a well-supported clade of flies distinguished by, among other features, their compacted antennae with distal flagellomeres modified into a slender style or hairlike arista. Within the Brachycera, Wiegmann et al. (2011) supported two basal clades, the Orthorrhapha and Eremoneura. The Eremoneura include the Cyclorrhapha and the long-legged empidoids; eremoneurans are united by the possession of three larval instars, larval mandibles with a single article, and adults with ocellar setae, one-segmented maxillary palps, and the cell cup in the wing closed apically or absent (Grimaldi & Engel 2005). They also include the relict Apystomyia elinguis, a small, superficially bombyliid-like fly found in California.
