Illustrated catalog of world Promecheilidae Lacordaire, 1859 (Coleoptera: Tenebrionoidea)

The family Promecheilidae Lacordaire, 1859 (= Perimylopidae St. George, 1939) has experienced a broad systematic redefinition and changes to its taxonomic composition during the last decade. Ten genera comprise this relatively small lineage, which is geographically restricted to the Holantarctic region. We further transfer the genus Dolphus Blanchard, 1847 from Tenebrionidae to Promecheilidae. The latter monotypic genus has been taxonomically problematic since its description due to the unique holotype being destroyed during its original species description. A full taxonomic catalog for the family is provided with type localities and references to synonymies, new combinations, and other nomenclatural changes. The catalog is illustrated with high-resolution images of type specimens housed in the Natural History Museum, London.
