Amauronematus anthracinus Lindqvist, 1959d: 11 .

Amauronematus macrophthalmus Lindqvist, 1959d: 13–14 . Syn. nov.

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).
