Acrocerinae is a subfamily of small-headed flies in the family Acroceridae. Their larvae are endoparasites of araneomorph spiders, with the exception of Carvalhoa appendiculata which can develop as ectoparasitoids on their host spiders. Traditionally, the subfamily included the genera now placed in Cyrtinae and Ogcodinae, but the subfamily in this sense was found to be polyphyletic and was split up in 2019.
Philopotinae is a subfamily of small-headed flies. They have an arched body shape, as well as enlarged postpronotal lobes that form a collar behind the head. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
Neophilopota is a genus of small-headed flies. It contains only a single species, Neophilopota brevirostris, described by Schlinger in 2013. It is endemic to Mexico.
Panopinae is a subfamily of small-headed flies (Acroceridae). Their larvae are endoparasites of spiders in the infraorder Mygalomorphae.
Pialea is a genus of small-headed flies. It is known from South America.
Ogcodes is a cosmopolitan genus of small-headed flies in the family Acroceridae. About 90 species have been described for the genus. It is the most common and speciose genus in its family. These flies are endoparasitoids of ground-dwelling entelegyne spiders.
Eulonchus halli is a species of small-headed flies in the family Acroceridae. It was named after one of its original collectors, Jack C. Hall, who was also a colleague of the species's author, Evert I. Schlinger, at the University of California.
Eulonchus is a genus of small-headed flies in the family Acroceridae. There are six described species in Eulonchus. The genus is found in North America. Adults have a metallic blue, green or sometimes purple coloration, giving them a jewel-like appearance. A common name for flies in the genus is the North American jewelled spider flies. Adults are also known as "sapphires" or "emeralds".
Lasia is a genus of small-headed flies in the family Acroceridae. There are about 19 described species in Lasia, which are distributed in the New World.
Eulonchus sapphirinus is a species of small-headed flies in the family Acroceridae.
Eulonchus tristis is a species of small-headed flies in the family Acroceridae.
Schlingeromyia is an extinct genus of small-headed flies in the family Acroceridae. The genus is known from Upper Cretaceous fossils in Burmese amber from Myanmar. It contains only one species, Schlingeromyia minuta.
Burmacyrtus is an extinct genus of small-headed flies of uncertain placement. The genus is known from Upper Cretaceous fossils in amber from Myanmar. It contains only one species, Burmacyrtus rusmithi.
Carvalhoa is a genus of small-headed flies in the family Acroceridae. The genus is endemic to Chile. It was originally known as Sphaerops, named by Rodolfo Amando Philippi in 1865. This name was found to be preoccupied by the reptile genus Sphaerops Gray, 1845, so it was renamed to Carvalhoa by Ahmet Ömer Koçak and Muhabbet Kemal in 2013. The genus is named after the Brazilian dipterist Claudio José Barros de Carvalho.
Schlingeriella is a genus of small-headed flies. It contains only one species, Schlingeriella irwini, endemic to New Caledonia.
Sabroskya is a genus of small-headed flies in the family Acroceridae. It is known from South Africa and Malawi. It is named after the American entomologist Curtis Williams Sabrosky.
Exetasis is a genus of small-headed flies. It is known from Brazil and Argentina.
Archipialea is a genus of small-headed flies in the family Acroceridae. It is endemic to Chile.
Arrhynchus is a genus of small-headed flies in the family Acroceridae. It was formerly considered a synonym of Ocnaea, but was reinstated as a valid genus by Schlinger in 1968. It is endemic to Chile.
Cyrtinae is a subfamily of the Acroceridae. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
