8 mm (n = 7) slightly dilated distally, white, suffused with pale brownish gray on basal area and anterior 4/5 of costal area, speckled with dark brown; sparse dark brown strigulae near to costa on basal 1/3 ; subbasal, antemedial and postmedian lines brownish gray, with golden luster, dark brown on dorsum; subbasal line rhomboid; postmedian line slender, sinuous on costal area; fringe dark brown with golden luster.
This species closely resembles Stachyotis epichrysa but can be distinguished from the latter in having the forewings with narrower subbasal, antemedian, and postmedian lines and a dark yellowish brown, semicircular patch along the terminal area; the male genitalia with shorter posterior processes on the uncus and upper apical portion of the valva tapering.
9 mm (n = 1), white, with dark brown, irregular strigulae along costa and posterior margin; subbasal and antemedian lines dark brown, almost perpendicular to dorsum; postmedian line XA as wide as medial line, constricted around anterior Va, blurred posteriorly; subterminal line dark brown, narrower than and almost parallel to postmedian line; terminal area with semicircular, dark yellowish brown patch; fringe mostly dark brown, white with dark brown tip on tornus Hindwing dark brownish gray, with dark brown streaks along veins; fringe dark yellowish gray.
Immediately after preparation it became evident that this taxon was unknown to science because it had a unique doubled postmedian line of the forewing in combination with a large triangular forewing dot, white pronounced veins, and the overall dark greyish brown colour plus details of its male genitalic structures listed below.

Forewing ground color brownish grey with yellowish brown spots, costa dark brown with yellow-brown patterns; apical costa with a distinct triangular black spot; mesial forewing with a pale blue kidney-shaped translucent spot, dorsum with some irregular yellow-brown patterns; postmedian transverse line indistinct, nearly straight with distinct white dots at veins.
Forewing elongate; ground color light orange to grayish orange; costa nearly straight; apex more or less acute; basal 2/ 5 of wing light orange to grayish orange, with three shining metallic blue, longitudinal streaks; first streak along subcosta, narrowed to apex; 2nd median, dilated apically; 3rd shorter, runs between cell and dorsum; median line almost vertical, light orange, narrow, with blackish scales along proximal side; median zone trapezoidal between median and postmedian line with oblique outer margin followed by a crescent blackish mark beyond upper corner of cell; a narrow leaden longitudinal streak between costa and [R.
