Tenderei a confermare, ma senza vedere il basitarso anteriore di profilo e la scultura di clipeo e mesoscuto non posso dirlo con certezza.

Il probasitarso appare come "ritorto" longitudinalmente; il mesoscuto ha punti radi, poco profondi, su fondo microreticolato.

Basitarso senza proiezione ventroapicale, clipeo con punteggiatura disposta in serie convergenti verso il centro e mesoscuto interamente reticolato ed opaco, si conferma E. nigrescens :hi:
