Edit: Just found out that fauna-eu is out of date regarding that genus. In a 2018 publication, E. notata was described from Lower Austria. I have a male, so what are the distinguishing features here?

Females of E. notata clearly differ in the golden yellow tergite 5 (whereas in pechumani it is dark brown and greenish subshining) Val

That would mean I found a new species for Austria in my garden :-) Female would have been easy, how do the males differ? Here another photo, not in situ this time...

In the northeastern United States E. notata is common. I have never seen E. pechumani and photos are much less common. In Europe the ratio seems to be more even.
