Nemedromia is a genus of true fly in the family Atelestidae. Nemedromia is extinct, with all three of its known species having existed in the Late Cretaceous epoch. [1] [2] [3]
Michael S. Engel, FLS, FRES is an American paleontologist and entomologist, notable for contributions to insect evolutionary biology and classification. In connection with his studies he has undertaken field expeditions in Central Asia, Asia Minor, the Levant, Arabia, eastern Africa, the high Arctic, and South and North America, and has published more than 983 papers in scientific journals and over 925 new living and fossil species. Some of Engel's research images were included in exhibitions on the aesthetic value of scientific imagery.
The Lonchopteridae are a family of small (2–5 mm), slender, yellow to brownish-black Diptera, occurring all over the world. Their common name refers to their pointed wings, which have a distinct venation. Many are parthenogenic; males are very rare, however, at least in North American species, and have a somewhat different venation than do the females.
Platypezidae is a family of true flies of the superfamily Platypezoidea. The more than 250 species are found worldwide primarily in woodland habitats. A common name is flat-footed flies, but this is also used for the closely related Opetiidae which were included in the Platypezidae in former times.
Atelestidae is a family of flies in the superfamily Empidoidea. The four genera were placed in a separate family in 1983; they were formerly either in Platypezidae or considered incertae sedis. While they are doubtless the most basal of the living Empidoidea, the monophyly of the family is not fully proven. The genus Nemedina seems to represent a most ancient lineage among the entire superfamily, while Meghyperus is probably not monophyletic in its present delimitation, and it is liable to be split up eventually, with some species being placed elsewhere. In 2010, the genus Alavesia, previously only known from Cretaceous fossils, was found alive in Namibia, subsequent species were also described from Brazil.
Acrocerinae is a subfamily of Acroceridae. They are small distinctive flies whose larvae are endoparasites of spiders. Adult hunchback-flies visit flowers to feed on nectar. 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.
Apystomyia is a genus of flies in the family Apystomyiidae. The genus contains the single living Apystomyiidae species, Apystomyia elinguis, which is primarily found in California. Details of its life history are largely unknown. The extinct genus Hilarimorphites is known from the Cretaceous Burmese and New Jersey ambers. Formerly placed in the Asiloidea, molecular phylogenetic studies in 2010 placed the genus unambiguously as a sister of the Cyclorrhapha within the clade Eremoneura.
New Jersey Amber, sometimes called Raritan amber, is amber found in the Raritan and Magothy Formations of the Central Atlantic (Eastern) coast of the United States. It is dated to the Late Cretaceous, Turonian age, based on pollen analysis of the host formations. It has been known since the 19th century, with several of the old clay-pit sites now producing many specimens for study. It has yielded a number of organism fossils, including fungi, plants, tardigrades, insects and feathers. The first identified Cretaceous age ant was described from a fossil found in New Jersey in 1966.
Cretomicrophorus is an extinct genus of flies in the family Dolichopodidae from the Upper Cretaceous of Russia, France and the United States. The generic name is a combination of the Latin word creta ("chalk") and the generic name Microphorus.
Microphorinae is a subfamily of flies in the family Dolichopodidae. It is part of an expanded concept of the family, Dolichopodidae sensu lato, though it was previously considered a family of its own.
Archichrysotus is an extinct genus of flies in the family Dolichopodidae. The generic name is a combination of the Greek prefix archi- and the generic name Chrysotus. The genus is known from Upper Cretaceous amber from the Taymyr Peninsula in Russia, New Jersey in the United States and Cedar Lake in Manitoba, Canada.
Avenaphora is an extinct genus of flies in the family Dolichopodidae. It is known from the Cretaceous of Lebanon and France.
Microphorites is an extinct genus of flies in the family Dolichopodidae.
Prohercostomus is an extinct genus of flies in the family Dolichopodidae, known from Baltic amber from the Eocene. It was originally created as a subgenus of Hercostomus, but was later raised to genus rank.
Apalocnemis is a genus of flies in the family Empididae.
Schistostoma is a genus of flies in the family Dolichopodidae, subfamily Microphorinae.
Eremoneura is a clade of flies within the Brachycera that includes the Empidoidea and the Cyclorrhapha and is a sister of the Asilomorpha. They are thought to have evolved around the Mesozoic. The group includes fossils described in the genus Chimeromyia from 125 million year old amber which show both empidoid and cyclorrhaphan characters. The monotypic family Apystomyiidae has also been placed within the Eremoneura as a sister of the Cyclorrhapha.
Umenocoleidae is an extinct family of dictyopteran insects known from the Cretaceous. They are considered to be closely related to the Alienopteridae. They were originally considered to be beetles due to their beetle-like morphology, with sclerotised elytra-like forewings. This was probably an adaptation for living under bark and in other tight spaces.
Tethepomyiidae is an extinct family of small brachyceran flies known from the Cretaceous period of Laurasia. It is part of the extinct superfamily Archisargoidea. The family is characterised by "very large eyes, reduced mouthparts, a highly reduced antennal flagellum, and greatly reduced venation." The ovipositor of Tethepomyia zigrasi has a hypodermic morphology likely used for injecting eggs into hosts.
Cretodromia is a genus of true fly in the family Atelestidae. Cretodromia contains no living members, with the only known species Cretodromia glaesa having existed in the Campanian age of the Late Cretaceous epoch.
Cretotabanus is a genus of horse flies in the family Tabanidae.
