Leptoconops
''Leptoconops'' (black gnat) is a midge genus in the family Ceratopogonidae. It has a mostly tropical or subtropical distribution worldwide, but some species occur as far north as Moscow region in Russia and the Yukon Territory in Canada. This genus is relictual, having had a pantropical distribution during the Cretaceous. The presence of ''Leptoconops'', along with '' Austroconops'', in ancient Lebanese amber makes these the earliest existing lineages of biting midges. Extinct species have also been described from amber from Siberia, New Jersey, Canada, Hungary, Sakhalin, France, and Spain. Adult ''Leptoconops'' females are diurnal feeders, and suck vertebrate blood Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.

Leptoconops Amplificatus
''Leptoconops amplificatus'' is an extinct species of biting midge belonging to the family Ceratopogonidae. This species was described from fossilized remains preserved in Lower Cretaceous amber from Lebanon. The species name ''amplificatus'' (enlarged, extended) was given in reference to the presence of 13 flagellomeres in the female antennae. ''L. amplificatus'' is the only species of Ceratopogonidae to possess this many antennal flagellomeres as well as an elongate, slender cercus. Another species of ''Leptoconops'' discovered in the same piece of amber, ''Leptoconops antiquus'', also possesses 13 flagellomeres, but is differentiated by a basally broadened cercus.
