ID of Mantoides gama

[DaveChiangMai]

The attached images were all taken (different dates) at Omkoi, nw Thailand. I've had these in my collection for several years labelled as Jacoona anasuja nigerrima, but recently it has been drawn to my attention that Mantoides gama maga also is likely to occur in the same area.

Looking at these images I feel that it's likely there are two species here. I note differences in the contrast between the upper and lower wings on the first two photos, as well as more blue scaling on them, plus the shape and positioning of the black lines and tornal spots.

My feeling is Image 1 and 2 are indeed Jacoona anasuja, but images 3 amd 4 relate to Mantoides gama.
Comments appreciated please.
