Clearly visible, but not well defined, a line that starts from the apex of the anterior wing to end in the internal margin in the disc region. This line is taken up in the discal region of the rear wing, making it appear, when the moth is at rest, a single straight line continues that runs from one apex to the other of the front wings, making an angle near the abdomen.
From the apex of the front wing starts a series of dark points, also ending in the inner edge of the wing. The edge of the wings is surrounded by an almost black dark line, more marked in some points almost like a hatch.

The hind wings have a series of dark spots, parallel to the line of the disc region, presenting a well pronounced angle near the third median vein (M3).
The head, thorax and abdomen have the background color of the wings.
