description: Genus Styphlidius Penecke, 1936
Type species: Adexius corcyreus Reitter, 1884.
Remark: The examination of specimens of all taxa of Styphlidius (Figs 1-9) except S. globosus [depicted in turn in Osella (1981)] allowed raising brevisetis and globosus to species level based on the morphological differences given in the key below. Furthermore a new fifth species of the genus is described below.
