Medina females have a peculiar “door-like” last tergite and often spiny bristles on the venter.

MorganA
Last tergit. Where is the venter?
 
Zeegers
Venter = belly Smile

Struggeld to get an good angel of the belly, hind legs always in the way!
 
Zeegers
It is male...

What would help if you could make a picture ot the thorac from above and obliquely behind showing the dust pattern, hence try to avoid the light reflections.

OK, there are 4 post DC, I could have seen that sooner. So this is pretty rare in Blondeliini. We might be barking up the wrong tree.
I haven’t seen the wing venation yet, but given the anterior postion of ocellar bristles, my candidate is now Bessa (in which case selecta). Bend of vein M should have a fold.
