Figs 234, 458

Amauronematus amicula Saarinen, 1950b: 47–49 . Holotype ♀ (http://id.luomus.fi/GL.3586, MZH). Type locality: Finland, Lapin Lääni , Outakoski.

Diagnosis

Extensively pale species (can be pink in life), but darker (median mesoscutal lobe and mesoscutellar appendage at least partly black) than E. rufa (median mesoscutal lobe and mesoscutellar appendage pale). Some specimens of E. striata are similarly pale, but have lamnium 1.6–1.7 times as long as radix (2.0–2.2 times as long in E. amicula , n = 2).
