The key by van Veen (https://home.hccn...ml#Thereva) tells us which characters have to be seen for an ID. A female would have a chance if we saw the face in frontal view. The shape of the black patch on the frons is a key character. With these two pictures alone, I would not dare to put a name on it, sorry!
