Lanistoides Sjöstedt, 1913 stat. rev.

The tribe Copiphorini contains six genera in Africa (excluding the genera endemic to Madagascar and St. Helena and the doubtful species Copiphora subulata (Stoll, 1813)): the closely related genera Euconocephalus and Ruspolia and the equally widespread Pseudorhynchus and the endemic Clasma, Lanista and Plastocorypha .

Another endemic genus, Lanistoides Sjöstedt, 1913, was placed in synonymy of Plastocorypha by Chopard (1955: 88), who obviously did not notice that both genera have different type species with same specific name (overlooked also by Otte 1997): Plastocorypha is based on Pseudorhynchus nigrifrons Redtenbacher 1891, Lanistoides on Lanistoides nigrifrons Sjöstedt, 1913 . Combining both genera would produce a secondary homonym and require a new name for Lanistoides nigrifrons Sjöstedt, 1913 . Since the tip of the fastigium verticis seems to be distinctly longer in Lanistoides nigrifrons than in Lanista and Plastocorypha (at least in the species figured in OSF), a character mentioned as typical for the genus by Sjöstedt (1913), and the shape of the head is different, we propose to re-establish Lanistoides as a valid genus.
