Sahlberg, 1876 nec Schönherr, 1836. Originally described from the Nearctic, <em>Gnathusa</em> is in fact a Holarctic genus with species in Norway, Sweden, Finland, Russia, China, USA and Canada. <em>Drepasiagonusa</em> Pace, 2012 is a junior subjective synonym of <em>Gnathusa</em> Fenyes, 1909. <em>Gnathusa feldmanni</em> (Assing, 2018) is regarded as a valid species, not a subjective junior synonym of <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876). Six new combinations are presented: <em>Gnathusa angulata</em> (Assing, 2018) (Drepasiagonusa); <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876) (Eurylophus); <em>Gnathusa feldmanni</em> (Assing, 2018) (<em>Drepasiagonusa</em>); <em>Gnathusa procera</em> (Assing, 2018) (<em>Drepasiagonusa</em>); <em>Gnathusa smetanai</em> (Pace, 2018) (<em>Drepasiagonusa</em>) and <em>Gnathusa tibetica</em> (Assing, 2018) (<em>Drepasiagonusa</em>). <em>Gnathusa seeversi</em> <strong>nomen novum</strong> is proposed for the secondary junior homonym <em>Gnathusa grandiceps</em> (Casey, 1911) [<em>Haploglossa</em>] not <em>Gnathusa grandiceps</em> (J. Sahlberg, 1876) [<em>Eurylophus</em>].</p> ER -
