Sphyracephala brevicornis
short-horned ankle-headed fly
Sphyracephala brevicornis is a species of stalk-eyed fly in the family Diopsidae, order Diptera. The common name "short-horned ankle-headed fly" refers to its relatively short eye stalks compared to other members of the genus. Stalk-eyed flies are characterized by their laterally projected compound eyes on elongated peduncles, a trait that is highly developed in this family. The species was originally described by Thomas Say in 1817 as Diopsis brevicornis.
