There are 31 myrmecophilous species in this Neotropical genus. The genus Peradon Reemer, 2013 (type species: Mulio bidens Fabricius, 1805) was erected to accommodate several Neotropical hoverfly species formerly included in Microdon Meigen, 1803. The morphological diversity of the species makes for a colourful genus. Reemer and Ståhls (2013a) distinguished three morphological species groups in this genus, i.e., bidens group, flavofascium group, and trivittatus group. Representatives of these species groups were recovered together with high support values in a phylogenetic clade based on an analysis of combined molecular and morphological characters (Reemer and Ståhls 2013b). Based on these findings, Peradon is considered to be a monophyletic group restricted to the Neotropics.

The colour patterns of several species seem to mimic those of certain Neotropical aculeates of the families Pompilidae and Vespidae (Hymenoptera).
