The subfamily Bruchomyiinae contains genera of moth flies in the order Diptera, was originally described by the American entomologist Charles Paul Alexander.

[1] For many years the Bruchomyiinae consisted of just three genera, distinguished by the number of segments in the antennae: Bruchomyia (24-29 segments), Eutonnoiria (111 segments) and Nemopalpus (14 segments).

A number of species of the cosmopolitan genus Nemopalpus were transferred in 2016, to the genera: Boreofairchildia, Laurenceomyia and Notofairchildia,[2] with oriental species subsequently (2018) placed in Alexanderia.
