( Figs 11 View FIGURES 9‒14 , 29 View FIGURES 27‒32 )

Type material. CHINA, Chongqing: Holotype • ♂, Dahonghai (28.65°N, 106.40°E), Mt. Simian , 1000 m, 18.VII.2010, leg. X.C. Du & L.F. Song, slide No. YAH12308. GoogleMaps

Paratypes: Guizhou: • 3♂, Sanchahe Town, Xishui , 767 m, 30.VI‒1.VII.2019, leg. M. R. Xing et al .

Diagnosis. The new species is similar to M. concaviuscula ( Wang, 2004) superficially. It can be distinguished by the valva almost evenly wide, the costa slightly concave at distal 1/3 and the aedeagus without a process beyond middle ventrally; in M. concaviuscula , the valva is narrowed basally and widened distally, the costa has a semicircular concavity at preapex and the aedeagus has an elongate triangular process beyond middle ventrally ( Wang 2004: 230, fig. 11).

Description. Adult ( Fig. 11 View FIGURES 9‒14 ). Forewing length 5.2‒5.8 mm.

Head with vertex and occiput yellow, frons yellowish white. Labial palpus yellowish white; second segment with scattered blackish-brown scales, with a blackish-brown ring at apex; third segment with blackish-brown scales distally. Antenna: scape yellowish white, mixed with brown scales on dorsal surface; flagellum yellow annulated with brown.

Thorax and tegula blackish brown. Forewing with costal margin arched, apex narrowly rounded; ground color blackish brown; median fascia yellowish white, broad, from middle of costal margin widened to dorsum; distal spot yellowish white, inverted triangular, at distal 1/4; plical spot small, composed of a few black scales, situated beyond middle; discal and discocellular spots black, placed beyond middle and at outer margin of cell respectively; fringe blackish brown. Hindwing blackish brown, fringe concolorous with wing. Legs yellow; on ventral surface, tibia of foreleg with scattered brown scales, tarsus blackish brown except yellow at base of basal tarsomere and at apices of basal two and apical one tarsomeres, tibiae of mid- and hindlegs blackish brown except yellow at middle and at apex, tarsus of midleg blackish brown except yellow at base of basal tarsomere and at apex of each tarsomere, tarsus of hindleg with basal three tarsomeres blackish brown except yellow at apices, all femora with scattered blackishbrown scales.

Male genitalia ( Fig. 29 View FIGURES 27‒32 ). Uncus sub-triangular, narrowed to rounded apex, with dense setae laterally in distal half. Tegumen inverted U-shaped, almost uniform in width, with a narrow sclerotized edge along outer margin. Valva almost evenly wide, with dense long setae distally; ventral margin with basal 1/3 straight, distal 2/3 obtusely arched; costa wide, slightly concave at distal 1/3, with several long setae basally; transtilla sub-triangular, narrowed toward middle, rounded at apex. Sacculus 2.5 times length of saccus; elongate sub-triangular, wide basally, narrowed distally, concave from near base to before middle dorsally, distal 1/3 heavily sclerotized, beak-like, curved dorsad, with long setae. Saccus shorter than uncus, triangular, narrowly rounded at apex. Juxta U-shaped. Aedeagus slightly longer than valva, tubular, uniform from basal 1/3 to middle, membranous distally, with a curved, sclerotized, irregularly shaped belt in distal half; cornuti being several spines ( Fig. 29a View FIGURES 27‒32 ).

Female unknown.

Distribution. China (Chongqing, Guizhou).

Etymology. The specific epithet is derived from the Latin curv - and taenianus, referring to the aedeagus with a curved belt in distal half.
