The genus Aspidiotes Schönherr, 1847 is revised; 6 species are recognized as valid. Amomphus Schonherr, 1848 is considered to be an unjustified replacement name for Aspidiotes Schönherr, 1847. Phaenognathus Schönherr, 1847 is retained as a subgenus of Aspidiotes although the cladistic analysis failed to find synapomorphies supporting this opinion. One new species, A. (Aspidiotes) gonzalezi, is described from NE Spain (Lerida, Thrragona and Zaragoza). A seventh species currently included in the genus, Amomphus reichei Desbrochers, 1872, is placed incertae sedis; the type specimen has not been traced. Distributional as well as biological data are provided. A cladistic analysis and a biogeographical discussion are provided.
