Archocyrtus is an extinct genus of small-headed flies in the family Acroceridae. The genus is known from compression fossils from the Late Jurassic Karabastau Formation of Kazakhstan.[1] The genus is the only member of the subfamily Archocyrtinae.[3]
A study on the holotype specimen of Archocyrtus kovalevi was published by Khramov & Lukashevich (2019). They reported evidence of an extremely long proboscis, almost twice the length of the body of the insect. They suggested that it was probably a pollinator of extinct seed plants belonging to the order Bennettitales.[4]
