Poplar Lutestring T. or is of similar size and shape, however in that species the white 80 mark is less clearly defined, often obsolete, there are four parallel fasciae in the antemedian region of the forewing, and the antemedian and postmedian lines diverge as they approach the costa instead of being parallel (MBGBI Vol 7 part 2).
