Correction: 10. Oriens gola female. Wear seems to have enhanced the brown spots.

In O. paragola the the veins are never so stronly pale. dividing the brown band into separate spots.
The HW band is always broad at the bottom (lowest spot wide) & the top arched.
https://4.bp.blogspot.com/-PM9bSjDGN..._mother_02.jpg
https://2.bp.blogspot.com/-vRbAQotDv...D_adult_04.jpg


In Oriens gola, the FW brown band is strongly interrupted by the pale veins.
The HW band is wide & flat at the top with a knob, & much narrower at the bottom.
