Well, the second flagellomere in the photo is discernible, and clearly longer than that of (male) E. rubicola. I consider this a reliable character. Don't you?
I'm sorry, but the answer is: No. Length isn't a useful character in this specific case. To distinguish these two species the 3rd antennomere is a useful character, but it's not used its length, while a ratio of its dimensions :)
Juergen, I'm quite sure, was right saying
Ectemnius ...even if we cannot stress its characters.
BTW: Yesterday I verified, and
rubicola can be excluded (because of the ratio of its 3rd antenna's ratio L/W). Problem is that its ratio exceeds that of a
continuus (>2!!).
