Scatopsidae. Several genera have curved CuA2 and a supernumary crossvein between R4+5 and M:
Scatopse (crossvein incomplete, not reaching R4+5),
Holoplagia (complete),
Colobostema (absent or incomplete),
Cookella (complete),
Ferneiella (incomplete). They should be separable by a combination of thorax length to width ratio and course of CuA2.
