One of the most recent classifications of Meloidae is based on the assumption that phoretic
first‐instar larvae evolved twice in the family, once in Meloinae and again in
Nemognathinae. Within Meloinae, this scheme places all presumed phoretic taxa in Meloini
regardless of other characteristics. This paper challenges this classification with a cladistic

Summary
One of the most recent classifications of Meloidae is based on the assumption that phoretic first‐instar larvae evolved twice in the family, once in Meloinae and again in Nemognathinae. Within Meloinae, this scheme places all presumed phoretic taxa in Meloini regardless of other characteristics. This paper challenges this classification with a cladistic analysis of all meloid genera whose first‐instar larvae were available for study. It concludes that phoresy evolved several times in Meloinae alone and that Meloini, when defined to include all phoretic genera, is polyphyletic. Cladistic support also is presented for four subfamilies of Meloidae and for several of the traditional tribes recognized in recent classifications.
