Archiinocellia is an extinct genus of snakefly in the family Raphidiidae known from Eocene fossils found in western North America.

Archiinocellia oligoneura is known from a single specimen collected by Canadian geologist and paleontologist Lawrence M. Lambe during fieldwork in central British Columbia.

[4] However, the site has been re-dated to the Early Eocene and is part of the Okanagan Highlands fossil localities, which stretch from Driftwood Canyon Provincial Park in Smithers, B.C.

[5] The Parachute Member of the Green River Formation is younger than the Horsefly Beds, with a Middle Eocene age, placing it in the Lutetian stage.

The type series plus an additional male specimen tentatively identified as also A. protomaculata are preserved in the Department of Paleobiology collections for the Smithsonians National Museum of Natural History.

[3] The Horsefly Beds and Green river Formation fossils were reexamined and redescribed by Archibald and Makarkin (2021), who identified A. protomaculata as a member of Archiinocellia rather than of Agulla.

[2] The holotype consists of a superimposed partial pair of wings, one forewing and one hindwing, thus not allowing for gender identification and body description.

[1] Though difficult to distinguish from one another, the forewing and hindwing vein structures show several distinct traits that set the genus apart from other raphidiopteran genera.
