Rohdendorf (1962) originally proposed the family Rhagionempididae for the single Jurassic genus Rhagionempis Rohdendorf, 1938, known at the time only from the Karatau deposits in Kazakhstan. Kovalev in Kalugina & Kovalev (1985) added the genera Probolbomyia Ussatchev and Ussatchovia Kovalev and treated the group as a subfamily within the Rhagionidae. Nagatomi et al. (1991) reviewed and gave a key to the genera, added the genus Palaeoptiolina Kovalev, and treated the group as a separate family related to the Empididae based on wing venation and antennal characters. It should be noted that figure 9 in Nagatomi et al. (1991: 595) which depicts "Rhagionempis dimidiata Meigen" [a recent species], is actually of the genus Rhagionempis Engel [preoccupied, = Leptempis Collin], not Rhagionempis Rohdendorf. All true Rhagionempididae are known only from fossils.
Lukashevich (1994) removed the genus Shevioptera Kalugina from the Eoptychopteridae and said it was close to the genera Rhagionempis and Ussatchovia. Shevioptera is treated in this catalog as questionably included in the Rhagionempididae pending further study.
In addition to the determined Mesozoic material listed here, undetermined Tertiary material of this family has been recorded from the Eocene amber deposits of the Caucasus (Zherichin, 1978: 15).
