Diagnosis. This species can be distinguished from its congeners by the forewing having purplish grey spots with metallic shine; and in the male genitalia by the beak-shaped uncus bilobed distally and a very short mesial plate of the gnathos.
Description. Adult ( Fig. 1 View FIGURES 1‒6 ). Wingspan 7.5–10.0 mm. Head with vertex and occiput brownish grey, frons silvery grey. Labial palpus with second segment ochreous yellow; third segment ochreous yellow except black distally. Antenna with scape grey on dorsal surface, black on ventral surface; flagellum black, annulated with white on dorsal surface. Thorax and tegula ochreous yellow, mixed with greyish brown basally. Forewing yellow; costal margin with a large diffused black patch at middle and a relatively smaller black spot at distal 1/4; other markings silvery white with varied metallic shine, margined with black scales: costal spot from beyond black costal patch extending obliquely outward to anterior angle of cell, another spot placed below black distal spot of costal margin; cell with a stripe from basal 1/4 oblique outward to basal 2/5 of fold, with a small spot below posterior angle; fold with a small spot at base and a larger spot above its basal 3/5; dorsum with four irregular spots, third one from base largest, outermost one indistinct; apical spot ovate; terminal spot rounded; tornal spot black, diffused, with a tiny silvery white spot placed at its inner side; cilia ochreous yellow. Hindwing and cilia deep grey. Fore- and midlegs black, femora greyish black ventrally, tibiae with a white spot basally and medially, with a tuft of white scales apically, tarsi white at apices of basal two tarsomeres; hindleg brown except black tarsus with basal two tarsomeres white at apices and distal two tarsomeres entirely white.
Male genitalia ( Fig. 19 View FIGURES 19‒24 ). Uncus wide at base, narrowed to basal 1/4, curved at distal 1/4 by a right angle; median part narrow, sclerotized laterally; distal 1/4 bilobed, beak-shaped, extending horizontally, pointed at apex. Gnathos shorter than uncus, slender; mesial plate very short, spatulate, rounded at apex; basal arm almost uniformly slender, more than four times length of mesial plate. Tegumen divided from posterior 2/5; lateral arm elongate triangular, narrowed anteriorly. Valva elongate, length more than three times of maximum width, narrowed from distal 1/3 to rounded apex; costa sclerotized, projected beyond distal 1/3; sacculus with basal half wide, distal half narrow, produced to a sclerotized free distal spine directed dorsad, forming a right ventroapical angle. Saccus narrowly elongate, triangular, wide at base, narrowed to pointed apex. Juxta with lateral arms heavily sclerotized, each arm being a wide plate with obtuse apex; basal lobe short, conical. Aedeagus shorter than valva, straight; cornutus more than half length of aedeagus, consisting of an apical spine and two middle spines, longer middle spine bifurcated distally.
Female genitalia ( Fig. 36 View FIGURES 36‒41 ). Apophyses anteriores more than half length of apophyses posteriores. Eighth sternum sub-rectangular, obtusely rounded on posterior margin, setose. Lamella antevaginalis widest medially, narrowed dorsad laterally. Antrum wide, with pleats posteromedially. Ductus bursae entirely sclerotized, widened and with dense spines posteriorly, narrow and with longitudinal wrinkles anteriorly. Corpus bursae membranous, round-ed; signum absent.
Distribution. China (Yunnan).
Etymology. The specific epithet of the new species is derived from the Latin color - and stigmosus, referring to the spots on the forewing.
