B e m e r k u n g e n: Diese Art lässt sich von Eu. americanus sicher nur durch den Aedoeagus bzw. die Untersuchung des 8. Sternits der Weibchen unterscheiden. Der Aedoeagus des Eu. pugetensis besitzt einen kürzeren Apikalteil des Medianlobus, die stark sklerotisierte dorsale Partie des Medianlobus ist deutlich tiefer ausgeschnitten als bei Eu. americanus (Abb. 33), das 8. Sternit der Weibchen ist am Hinterrand nur leicht ausgerandet, bei Eu. americanus erheblich tiefer ausgeschnitten ( Abb. 68 ). Da beide Arten auch zusammen erbeutet wurden, kommt man um eine Genitalpräparation nicht herum.
