( Figs 4 View FIGURES 1−6 , 10 View FIGURES 7−12 , 14 View FIGURES 13−15 )

Type material. CHINA, Sichuan: Holotype ♂ , Mt. Sigu'niang (30.98°N, 102.83°E), Xiaojin County, 3243 m, 3.VII.2016, leg. KJ Teng & XF Yang, slide No. ZXJ19499 GoogleMaps . Paratypes: 8♂, 4‒6. V.2016, other same data as holotype, slide Nos. ZXJ19478, ZXJ19322 GoogleMaps ; 1♂ 1♀, Shaoyaogou, Anzi River, Chengdu , 1598 m, 19. VI.2016, leg. KJ Teng & XF Yang, slide Nos. ZXJ19504 ♂, ZXJ19622 ♀.

Diagnosis. M. hirsuta is similar to M. plicata Yin, Zhi & Cai, 2020 as the sacculus being produced to a thumb-shaped process distally. It can be distinguished by the lanceolate uncus and the costa without a small process distally. In M. plicata , the uncus is clavate and the costa has a small process distally ( Yin et al. 2020: 26, Fig. 4 View FIGURES 1−6 ). It is also similar to M. dorsidentata sp. nov., and the differences between them can be found in the diagnosis of M. dorsidentata .

Description. Adult ( Fig. 4 View FIGURES 1−6 ). Forewing length 5.5–6.0 mm.

Head yellow; occiput black laterally. Labial palpus yellow; first and second segments with dense black scales on outer surface, black at apex on second segment; third segment with black scales in distal 2/3. Antenna black, flagellum alternated with yellow on ventral surface.

Mesonotum and tegula black. Legs yellow, with exceptions on ventral surface: foreleg black except tibia yellow at apex, tarsus yellow at apices of basal four tarsomeres and on entire apical tarsomere, midleg black except femur yellow distally, tibia yellow at middle and at apex, tarsus yellow at apex of each tarsomere, tibia of hindleg with scattered dark brown scales, tarsus with basal four tarsomeres dark brown, yellow at apices.

Forewing lanceolate, apex rounded; ground color yellow, with black scales, dense black scales forming wide black stripe along basal 2/5 of costal margin; median fascia black, obliquely extending from before middle of costal margin to end of fold; subterminal fascia black, extending from distal part of costal margin along termen to tornus, nearly entirely fused with median fascia only leaving small yellow dot at distal 1/5 of costal margin; plical spot black, at distal 2/5 of fold; discal and discocellular spots black, placed at middle and at outer margin of cell respectively, discal spot small, rounded, discocellular spot larger, banded; fringe black, with a yellow basal line. Hindwing and fringe deep grey.

Male genitalia ( Fig. 10 View FIGURES 7−12 ). Uncus lanceolate, rounded at apex. Tegumen inverted V shaped, wider medially, narrowed to rounded at anterior end laterally. Costal part of valva wide at base, gradually narrowed to rounded apex; ventral margin produced, with a setose region near base; costa uniform, bent, almost extended to apex of costal part; transtilla short, blunt at apex; sacculus wide at base, somewhat narrowed to middle, distal half produced to thumb-shaped process, ventral margin folded basally, concave beyond middle. Saccus sub-triangular, wide at base, narrowed to rounded apex, as long as uncus. Juxta U-shaped; narrowed in basal 1/2, uniformly narrow in distal 1/2. Phallus shorter than costal part of valva; narrow at base, widened to 1/2, thereafter narrowed to rounded apex; apex produced to two sclerites: smaller sclerite concave apically, forming two spines, larger sclerite banded, curved toward base, reaching basal 3/5.

Female genitalia ( Fig. 14 View FIGURES 13−15 ). Papilla analis sub-rectangular, setose on dorsal surface. Apophysis posterioris approx. 3.0 times as long as of apophysis anterioris. Eighth tergite sub-trapezoidal. Eighth sternal plate with narrow median groove, laterally with semielliptical plate narrowed to posterolateral corner, lined with long stout setae on posterior margin. Ductus bursae heavily sclerotized except membranous anteriorly; ductus seminalis arising from junction of ductus bursae and corpus bursae. Corpus bursae ovate; signum very small, composed of a few denticles, placed at posterior 2/5.

Distribution. China (Sichuan).

Etymology. The specific epithet is derived from the Latin hirsutus, referring to the costal part of the valva with a setose region near the base of the ventral margin.
