Two new species of Diodontus Curtis, 1834 (Hymenoptera: Pemphredonidae) are described. Diodontus polytylus Budrys new species is widespread in North Africa, from Libya and Chad to Morocco, as well as in southern Spain and Portugal. Diodontus guichardi Budrys new species was found in several localities in Morocco. The new species have small differences in their morphology; however, they can be easily separated using molecular characters. Comparison of 17 molecular markers has revealed that the highest evolutionary divergence is observed in mitochondrial gene ND6 and internal transcribed spacer ITS2. The variable regions of the nuclear rDNA genes 18S and 28S demonstrated the lowest evolutionary divergence; thus they were of the least use for species identification. The most coherent reconstruction of phylogeny, in comparison to other groups of markers, was obtained using exons of nuclear protein-coding genes. A provisional key to the species of D. minutus (Fabricius, 1793) species group of the Mediterranean Region is presented.
