I think most of us would not hazard a guess beyond Usia but thre may be a few around who are more knowledgable.

I don't have real experience with this species but your specimen fits the theory Wink Try to find the males, which are very distinctive, with olive dust on thorax and abdomen and a patch of golden-red dust on the later.
