The bee family Melittidae comprises a small, but biologically fascinating, group of mostly oligolectic bees, some of which are oil collecting. Phylogenetic relationships within this family are poorly understood and some genera cannot be placed with confidence at the subfamily level. We analysed melittid phylogeny using a combined dataset of five nuclear genes [28S, elongation factor‐1α (EF‐1α, F2 copy), long‐wavelength rhodopsin, Na‐K ATPase and RNA polymerase II] spanning 4842 bp plus 68 adult morphological characters. Our study included 25% of the species‐level diversity and 81% of the generic‐level diversity and included all previously recognized tribes and subfamilies. We analysed the dataset using parsimony, maximum likelihood and Bayesian methods. All methods yielded congruent results. All topologies recovered the three previously recognized subfamilies (Dasypodainae, Melittinae, Meganomiinae), but two genera (Afrodasypoda and Promelitta) are transferred from Dasypodainae to Melittinae. On the basis of our tree topologies we identify four tribes (Dasypodaini comb.n., Hesperapini stat.n., Macropidini comb.n. and Melittini), only one of which (Melittini) matches a widely used classification. Lastly, we discuss the evolution of host‐plant association in the light of our new phylogenetic hypothesis. Our results strongly support multiple independent origins of oil‐collecting behaviour in the Melittinae.
