Amauronematus distinguendus Enslin, 1915: 381 . Lectotype designated below.

Diagnosis

Females are most similar in colouration (mostly black body and black pterostigma) and lancet structure to E. toeniata , but the malar space is about 1.0–1.2 times as long as diameter of front ocellus (more than 1.2 times in E. toeniata ). Males are coloured similarly to the females and in combination with examination of the penis valves can be reliably separated from the other species of Euura .
