MoV (Part 8) provides a key for distinguishing D. gerula, D. aglossoides, and D. igneapicta, Overall colouration (gerula: grey; aglossoides: brown; igneipicta: reddish brown) A key identifying feature suggested is the 'bulge' in the main forewing line. Its a 'double bubble in D. gerula and D. aglossoides, but 'straight but with short jagged edges, variable' in D. igneipicta. The blotch marks along the costa are 'pale: D . gerula; 'brownish, tinged, pale brown': D . aglossoides and reddish or orange: D. igneipicta. Therefore I'm suggesting, on balance, D. aglossoides.
