Analocostreptus missionarius (Attems, 1953) comb. nov.
Remarks. Spirostreptus procerus Gerstäcker, 1873 has, at least since Attems (1914), been regarded as a synonym of the widely distributed East African species Archispirostreptus gigas (Peters, 1855). Nevertheless, because of the primary homonymy, a replacement name is required for Spirostreptus procerus Attems, 1934, a species described and repeatedly recorded from D.R. Congo (Zaire). The synonym S. missionarius Attems, 1953, is available and is here, as Analocostreptus missionarius (Attems, 1953), accepted as the valid name of the species.
