Amauronematus varians Lindqvist, 1962a: 120–121 . Syn. nov.

Diagnosis

Females (6.5–8.0 mm) are most similar to E. hyperborea , but pronotum and tegula are distinctly pale (black in E. hyperborea ) and the hairs on head and thorax are somewhat shorter. Males are not clearly distinguishable from melanocephalus group species with a pale pterostigma ( E. cadderensis , E. ferruginea , E. kangasi ).
