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

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. Theo |

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. Theo |
