Diagnosis. The new species can be distinguished from other members of the rubra species-group by the forewing with a large rounded white costal spot crossing the anterior angle of the cell.

Description ( Fig. 3 View FIGURES 1‒6 ). Adult. Forewing length 7.0‒ 8.5 mm. Head with vertex dark brown, frons orange yellow, occiput blackish brown. Labial palpus: second palpomere yellow on inner surface, orange yellow on outer surface; third palpomere brown except white apically. Antenna: scape cream white on dorsal surface, dirty white on ventral surface; flagellum cream white on basal several flagellomeres, black alternated with white on rest of flagellomeres dorsally, black ventrally. Thorax and tegula greyish black. Forewing orange yellow; markings white edged with black scales: costal spot large, sub-ovate, running from distal 1/3 to above posterior angle of cell; antemedian fascia from basal 2/5 of dorsum extending to basal 1/4 of costal margin, slightly curved outward; dorsal streak from before tornus obliquely inward to posterior margin of cell at middle length of forewing; fringe orange yellow. Hindwing and fringe grey. Foreleg white ventrally, black dorsally, tibia with a white spot at base and middle respectively, with a tuft of white scales at apex, tarsus white at apices of basal two tarsomeres; midleg with femur yellowish brown, tibia white, with a tuft of black scales at apex, tarsus black, white at apices of basal two tarsomeres, apical tarsomere white dorsally; hindleg greyish brown, tarsus white from apex of basal tarsomere to apex of apical tarsomere.

Male genitalia ( Fig. 9 View FIGURES 7‒10 ). Uncus with basal half wide and subparallel, distal half narrowed to pointed apex. Gnathos slightly longer than uncus; mesial plate lingulate, squamous distally, with a membranous apical process. Tegumen separated from posterior half; lateral arms narrowed to pointed apex. Valva sub-rectangular, with a sclerotized, densely setose, semicircular area distally, oblique at apex; costa straight; sacculus banded, narrowed distally, produced to a free apex-pointed distal process directed obliquely dorsad, exceeding tip of costa. Saccus about half length of valva, uniformly wide to before narrowly rounded apex. Juxta narrowly linked basally; lateral arms clavate, uniformly wide, apically rounded, reaching anterior 1/4 of tegumen. Aedeagus with basal half slender, distal half inflated, with two spines apically; cornutus absent.

Female genitalia ( Fig. 10 View FIGURES 7‒10 ). Apophyses anteriores about half length of apophyses posteriores. Eighth sternum rectangular. Lamella postvaginalis sub-rounded, slightly widened posteriorly, posterior margin broadly obtuse, with setae. Antrum elongate rectangular. Ductus bursae extremely short, shrunken, membranous, with a small sclerite at left side posteriorly. Corpus bursae membranous, ovate; signum sub-ovate, with dense denticles, margined with larger spines.

Distribution. China (Shaanxi, Sichuan).

Etymology. The specific epithet of the new species is derived from the Latin magni - and stictus, referring to the large costal spot of the forewing.
