Amauronematus aeger Konow, 1895: 181 . Lectotype designated by Oehlke & Wudowenz (1984). Amauronematus dalecarlicus Malaise, 1921a: 2–3 . Synonymy by Lindqvist (1962a).

Diagnosis

Mostly black, brown or pale pterostigma, “ Amauronematus - type ” head, bifid claws, square-shaped valvula 3 with distinct invagination. Most similar species is E. hebes (character states in parentheses), from which it differs by having smoother mesepisternum (usually strongly matt) and paler pronotum (completely black or nearly so). Males possibly not clearly distinguishable from other aegra group species. Females sometimes with extensively brown mesepisternum and head (e.g., ZMUO.031774, ZMUO.031807).
