Ten previously described species are as follows: S. brachyurus(Dubinina, 1964), S. grandis (Dubinina, 1964), S. fedjushini (Dubinina, 1964), S. gozdziewskii Bochkov et al., 2012, S.insignis Fain and Lukoschus, 1985, S. modestus Fain and Lukoschus, 1985, S. pusillus Fain and Lukoschus, 1985, S.radiatus Fain and Lukoschus, 1985, S. subornatus Fain and Lukoschus, 1985, and S. zurowskii Bochkov et al., 2012.Schizocarpus intercalatus Fain and Lukoschus, 1985 syn. nov. and S. parabrachyurus Fain and Lukoschus, 1985 syn. nov.are considered as junior synonyms of S. brachyurus; S. ventricosus Fain and Lukoschus, 1985 syn. nov. is considered as a junior synonym of S. latus (Dubinina, 1964).
