Genus Nysius Dallas, 1852

Stål, 1872c created the subgenus Macroparius on the basis of Nysius graminicola sensu Stål, 1872 (non Kolenati, 1845!) (= Nysius stalianus Horváth, 1890; = Nysius immunis (Walker, 1872)). Subsequent authors (except Horváth), considered Macroparius as representative of the group of N. graminicola; then Wagner, 1958v created for the group of immunis his subgenus Tropinysius. Fixing a type species for Macroparius, now a synonym of Nysius, will put useless trouble. If a further reviser needs to return to this problem, she or he should have the opportunity to take action.
