The phylogeny of the family is virtually unexplored, its evolutionary history obscure; thus, the existing classification is controversial and likely artificial. We generated the first multi-gene higher-level phylogeny estimate of Anthribidae using DNA data from 400 nuclear genes obtained via anchored hybrid enrichment from 40 species representing 17 tribes plus genera <i>incertae sedis</i>. As in previous studies, the family Anthribidae was consistently recovered as the sister group of Nemonychidae. We recovered two main clades in Anthribidae as sister groups with strong statistical support, viz. a monophyletic subfamily Urodontinae and the traditionally recognized Anthribinae, which was rendered paraphyletic by the subfamily Choraginae. Paraphyly and polyphyly among tribes of Anthribinae indicate that current tribal concepts—all based on morphology and without phylogenetic analysis—are artificial. Based on our results, we subsume the subfamily Choraginae into Anthribinae and place its six current tribes (Apolectini, Araecerini, Choragini, Cisanthribini, Valenfriesiini and Xenorchestini) in an expanded subfamily Anthribinae. We also transfer three genera currently treated as Anthribinae <i>incertae sedis</i> to three generally recognized tribes, namely <i>Pleosporius</i> Holloway to Sintorini, <i>Xylanthribus</i> Kuschel to Proscoporhinini and <i>Anthribidus</i> Fåhraeus to Platystomini. The phylogenetic positions of Urodontinae and Trigonorhinini suggest that phytophagy is the ancestral feeding mode of Anthribidae, with a few taxa of Anthribinae having secondarily evolved plant-feeding from mycetophagy, the predominant feeding habit of the subfamily.

Despite considerable progress in taxonomy and classification, no robust phylogenetic hypothesis currently exists for the tribe that could form a framework for a better understanding of the evolution of ant attendance in the group. Here, we reconstruct the phylogeny of the Luciini based on an extensive molecular dataset (up to 391 genetic loci for 101 ingroup samples representing 17 (77%) species and all four genera). Bayesian and maximum likelihood analyses found that the genus <i>Pseudodipsas</i> C. &amp; R.
