Ripiphoridae phylogeny inferred from rRNA and mtDNA markers and 23 taxa from four subfamilies is presented. Despite much denser sampling than previous studies and completeness of the assembled dataset, the phylogenetic signal from molecular markers remains ambiguous. The dataset does not support monophyly of Ripiphoridae and suggests the Ripiphoridae Mordellidae clade with ripiphorid lineages forming gradual splits basally to Mordellidae. Previous hypotheses on relationships of Meloidae and Ripiphoridae and a single origin of developmental modifications are refuted. The ripiphorid subfamilies are regularly recovered and we found Pelecotominae and Ptilophorinae among deep splits. Ripidiinae, despite morphological divergence, are regularly found within the ripiphorid mordellid clade in a sister relationships to Ripiphorinae Mordellidae. Molecular phylogeny of Ptilophorus Dejean supports a hypothesis about their Gondwanan origin and subsequent dispersal to the Northern hemisphere. The clade Macrosiagon Hentz Metoecus Dejean is well defined and majority consensus suggests a terminal position of Metoecus within Macrosiagon and the inferred subclades agree with the morphology-based species-groups. Ripiphorus caboverdianus Batelka & Straka, 2011 is lowered to a subspecies of R. arabiafelix Batelka, 2009.
