Type material. CHINA, Xizang: Holotype ♂, Nongmu (29.67°N, 94.32°E), Linzhi City , 3080 m, 1.VII.2019, leg. MJ Qi & JQ Deng, slide No. ZXJ19354 GoogleMaps . Paratypes: 1♂, same data as holotype GoogleMaps ; 3♂ 22♀, Gu Town , Bomi County, 2623 m, 30. VI.2019, leg. MJ Qi & JQ Deng, slide Nos. ZXJ19351 ♂, ZXJ19582 ♀.

Diagnosis. The new species is similar to M. conica Wang, 2020 (In Zhu et al., 2020) in male genitalia. It can be distinguished by the uncus sub-parallel to before narrowly rounded apex, the distally inflated valva with a short ventroapical spine, and the sacculus globularly dilated. In M. conica , the uncus is distinctly narrowed to a pointed apex, the distally narrowed valva lacks a ventroapical spine, and the sacculus is straight at apex ( Zhu et al., 2020: 151, Fig. 17 View FIGURES 16−21 ).

Description. Adult ( Fig. 12 View FIGURES 10−15 ). Forewing length 7.0– 7.5 mm.

Head pale yellow. Labial palpus yellow; first and second palpomeres with scattered black scales on outer surface; third palpomere with sparse blackish-grey scales on outer surface, half length of second palpomere. Antenna yellow; scape with scattered blackish-grey scales; flagellum ringed with blackish grey.

Thorax yellow, mixed with blackish-grey scales; tegula black, mixed with yellow scales distally. Forewing ground color pale yellow, with black scales, with an ill-defined black stripe in basal 1/3 of costal area; plical spot black, rounded, at distal 2/5 of fold; discal spot black, placed at middle of cell; discocellular spots doubled, situated at anterior and posterior angles of cell; fringe pale yellow, tipped with blackish grey. Hindwing and fringe yellowish grey. Legs yellow; on ventral surface, foreleg black except tibia yellow at apex, tarsus with basal three tarsomeres yellow at apices, midleg black except tibia yellow at middle and at apex, tarsus yellow at apices of basal four tarsomeres, hindleg with scattered blackish-grey scales.

Male genitalia ( Fig. 24 View FIGURES 22−27 ). Uncus sub-parallel to before narrowly rounded apex, setose laterally. Tegumen banded, narrowed medially; lateral arm widened medially, narrowed anteriorly, obtuse at apex. Valva narrow at base, widened to basal 3/5, thereafter uniformly wide to before apex, setose distally; apex obtusely rounded, with a short ventroapical spine; ventral margin convex medially; costa concave basally; transtilla weakly sclerotized, clavate. Sacculus wide at base, narrowed to basal 2/3, distal 1/3 globularly dilated, setose. Saccus wide at base, narrowed to rounded apex, wider than and as long as uncus. Juxta V-shaped. Aedeagus slender, tubular, bent medially, with two bands of clustered denticles in distal 1/3.

Female genitalia ( Fig. 34 View FIGURES 32−35 ). Papilla analis sub-quadrate, setose. Apophyses posteriores approximately 2.5 times as long as apophyses anteriores. Eighth tergite trapezoidal. Eighth sternal plate eyebrow-shaped, lined with long stout setae on posterior margin. Antrum weakly sclerotized, sub-trapezoidal. Ductus bursae sclerotized in posterior half, membranous in anterior half; ductus seminalis arising from anterior 1/3 of ductus bursae. Corpus bursae elliptical; signum absent.

Distribution. China (Xizang).

Etymology. The specific epithet is derived from the Latin globulosus, referring to the distal shape of the sacculus.
