Overview of the information on the taxonomic spectrum of both mutillids and their hosts reviewed in this study.

Confirmed host associations are here resumed as lists of host genera and subfamilies overall recorded for each mutillid genus (number of species in brackets and number of records shown in the rightmost column), tribe and subfamily. For the complete information on all host associations at species-level, together with ecological data for each host record and the associated references, see the (S1 Table).
