1923  Schizoclymenia drevermanni Schindewolf: 480.
     1981  Schizoclymenia drevermanni.-Bogoslovskiy: 77, fig.30b.

[Schindewolf (in Treatise 1957, p.L40) stated that Schizoclymenia
is an objective synonym of Gonioclymenia. In his manuscript for
the new edition of his Treatise part he stated (1971) that this
genus was based on a misinterpretation of internal suture line;
therefore, the species drevermanni has to regarded as an
objective synonym of speciosus Nünster.]
