I beleive this is Hypochrosis hyadaria.

While there is some general similarity between species of Heterolocha that resemble Hypochrosis hyadaria I will point out a few noticeable differences based on images found on the internet.

In Hypochrosis hyadaria the antemedial and postmedial lines of both wings are distinct and nearly straight. The forewing postmedial line is highly angled just below the costa before the apex.

In species of Heterolocha that resemble Hypochrosis hyadaria you will find that these lines are curved and often indistinct or diffuse. The forewing antemedial line is irregular or crenulate and is curved upwards closer to the base of the costa. In Hypochrosis hyadaria it meets the costa nearly at the middle. Also, Hypochrosis hyadaria does not possess the hindwing cell spot as seen in Heterolocha.

Therefore, your specimen is Hypochrosis hyadaria.

Here is an image of a specimen at BOLD Systems that closely matches yours. It has been erroneously determined as a Heterolocha sp.

Update: Heterolocha sp. I guess. But what about species.
Somebody?
