interpunctatum complex
I am pretty sure on form but with one view it limits things. I am comfortable with calling this interpunctatum /frontale based on;

germinate median dorsal line tergites 1-4, black ringed lateral ocelli, pale forewing roots, faint median bandings on rear femora, spots on the clypeus below antenna, mid-cranial spot, and most important and rare on the darker forms, yellow scutellum.
