Ceratopogonidae. The long front claws are found only in predatory groups, all of which are in subfamily Ceratopogoninae. Some believe that Ceratopogoninae are not monophyletic.

Compare
Fossihelea gracilitarsis (Meunier, 1904) and
Stilobezzia. You may be able to distinguish them with
Szadziewski, Ryszard. 1988. Biting midges (Diptera, Ceratopogonidae) from Baltic Amber. Polskie pismo entomologiczne, 58(1): 3-283
Both genera are in tribe Ceratopogonini; Stilobezzini was synonymized after the paper was published.
