Diagnosis: Tarache augustipennis is sexually dimorphic. The male has elongate forewings. The costa of the forewing is yellow-white stretching from the base of the forewing to to nearly the apex. The lower half of the forewing is brown. The lower half of the antemedial line is represented by a vague series of dark brown dashes. Similarly the postmedial line is also represented by dashes, but the dashes are much more distinct. The orbicular is absent. The reniform is a dull, gray, white circle with a black spot in the center. There are two brown stripes reaching the costa starting from the general vicinity of the reniform. The subterminal are ais yellow with patches of gray. The terminal line is a series of short, black dashes.

The female is not nearly as yellow as the male. There is brown dash arising on the costa and joining the lower brown half of the wing cutting off a vaguely elongate, ovate white patch.

Wing expanse from base to apex in one selected individual 13 mm.
