Monotypic group, only containing the species Stomis stefani Deuve, 2006 , from Taiwan. It is characterized by the combination of: length rather short (10.1–10.8 mm); color black very shiny, head rather large, with very long mandibles, the right one without notch; pronotum rather flat, markedly dilated anteriorly, rather densely punctate both near base and near anterior margin, with one anterolateral seta; elytra rather long, dilated in the apical third, with markedly punctate striae; aedeagus rather short, with apical lamella triangular and apex, in lateral view evidently curved upwards.
