Anthidium (Anthidium) spiniventre Friese, 1899 and Anthidium (Anthidium) melanopygum Friese, 1917

Anthidium melanopygum Friese, 1917 was considered a subspecies of Anthidium spiniventre Friese, 1899 and was elevated to species level by Kasparek & Fateryga (2023) based on both morphological and genetic analyses. It has a wide distribution that extends from Greece and Bulgaria in the west and across Turkey and Iran to Turkmenistan in the east. Conversely, A. spiniventre has a more restricted distribution in the southern Levant and Iran. The taxon melanopygum therefore replaces spiniventre in the checklist of European bees.
