The classification adopted here is fairly conventional, morphology based, but slightly updated according to results obtained from analyses of molecular data presented in particular by Kutty et al. (2014) . It recognizes eight subfamilies, seven tribes and 179 genus-group taxa ( Table 1 ). Species from 115 muscid genera and subgenera have presently been examined for the distribution of setulae ventrally and dorsally on vein C (character A ) in agreement with the nine states described above ( Table 1 ).
