Cossonus Clairville, 1798 Comments on classification. The world fauna of the genus Cossonus Clairville, 1798, with over 300 species, is badly in need of revision, and most probably a future reviser will be forced to split them among different genera, not necessarily corresponding to the poorly defined ‘subgenera’ into which this taxon is currently in part divided; these are not used here. Nomenclature note. During my study of Afrotropical Cossonus for comparison with Socotran taxa described below, I have discovered, that Cossonus gibbirostris Hustache, 1936 from Ethiopia (HUSTACHE 1936b: 580) is a junior primary homonym of C. gibbirostris Roelofs, 1876 from Japan (ROELOFS 1876: cxxxiv), and thus the new substitute name of Cossonus alphonsephilus nom. nov. in memory of Alphonse Hustache is here proposed for the Ethiopian species.
