Genus Schistoneurus Mamaev, 1964

The genus Schistoneurus previously contained two species, S. irregularis Mamaev, 1964 and S. impressus Mamaev, 1964, whose distribution is northern and central Europe (Gagné & Jaschhof 2021). While the presence of S. irregularis in Germany was recently evidenced (Jaschhof & Jaschhof 2021b), German records of S. impressus are still absent. Contrary to my expectations, the present project found two previously unknown species close to S. impressus, which are described below.
