Spirostreptus procerus Attems, 1934: 165 , nom. occ. not: Spirostreptus procerus Gerstäcker, 1873: 508 Spirostreptus missionarius Attems, 1953: 68 , synonymized with S. procerus Attems, 1934 , by Kraus (1958: 32) 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.
