Ischnocolus tunetanus Pavesi, 1880

Despite exhaustive research, the type-specimen, from Tunisia, was not located. It is possible that it is a junior synonym of I. valentinus, considering the overlapping of their geographical distributional range, and that I. valentinus is a wide spread species in northern Africa and Mediterranean region in Europe. The original description does not warrant recognition of the species and, therefore, the identity of I. tunetanus cannot be confirmed. The species is here considered species inquirenda, pending the finding of the type material or availability and careful examination of material from the type locality.
