This document studies the genus Ctenophorellus Silvestri, 1920 with the species Ctenophorellus afer Silvestri, 1920. The holotype is still present in the collections preserved at the Filippo Silvestri Entomological Museum in Portici. The monotypic genus Ctenophorellus (incertae sedis) was found to be a genus inquirendum and therefore Ct. afer is a species inquirenda. Furthermore, other proposed taxonomic acts are: Orthosilis Motschulsky, 1860 nomen dubium and Telerhina Motschulsky, 1860 nomen dubium.
