Based on the newly available material, the taxonomic concepts of the genera Lawrenceus Iwan, 1998, Platycharlesus Iwan, 1998, Schelodontes Koch, 1956 and Warchalowskiellus Iwan, 1998 are verified. The results of a comparative morphological analysis reveals continuities and several ambiguities between some of the diagnostic characters of these genera. To update the current classification of the subtribe Platynotina and to fulfil the usefulness of the taxonomic system, we propose to treat Lawrenceus, Platycharlesus and Warchalowskiellus as junior synonyms of Schelodontes. We also propose the following combinations: Schelodontes capensis (Iwan, 1998) comb.n., S. dentatus (Iwan, 1998) comb.n., S. invenustus (Iwan, 1998) comb.n., S. chevrolati (Mulsant & Rey, 1853) comb.restit., S. longulus (Mulsant & Rey, 1853) comb.restit., S. morosus (Mulsant & Rey, 1853) comb.restit., S. oblitus Koch, 1956 comb.restit., S. omeri Koch, 1956 comb.restit. Additionally, in the material from Ditsong National Museum of Natural History we found four new phenons which we described as new species: Schelodontes muellerae sp.n., S. nitidus sp.n., S. scarabaeoides sp.n. and S. spinosis sp.n. A checklist and key to all species of the genus Schelodontes is provided.
