Paratypes: 1♁, Taiyanghe, 1450 m, 3.VI.2014, leg. ZG Zhang; 1♁, Taiyanghe, Pu’er City, 8.VI.2015, leg. ZG Zhang, slide No. ZD21218.

Diagnosis. The new species can be distinguished in the male genitalia by the left socius inflated distally, and the left valva with distal half dilated elliptically. It is similar to M. solidilatata sp. nov., and the differences between them are stated in the diagnosis of the latter species.

Description. Adult ( Fig. 3 ). Wingspan 11.5–12.5 mm.

Head with frons and vertex dark brown, frons with white longitudinal line laterally.Antenna dark brown except scape white terminally, with a white longitudinal line on ventral surface; flagellum annulated with white dorsally. Labial palpus: second palpomere taupe brown, with a white longitudinal line on ventral side, ringed with white at apex on dorsal side; third palpomere dark brown, with a white streak running from base to apex on ventral side.

Thorax and tegula dark brown. Forewing dark brown; subbasal fascia oyster white, slightly widened from costal 1/6 to dorsal 1/4; same sized white spot at 1/2 and 5/6 of costal margin as well as at tornus; fringe dark brown. Hindwing and fringe taupe brown. Foreleg white mixed with brown scales dorsally, dark brown ventrally, first tarsomere ringed with white at base and apex; midleg dark brown, except tibia and first tarsomere ringed with white at base and apex, fifth tarsomere pale yellow; hindleg dark brown on outer surface, except tibia white at basal 1/7 and apex, tarsus mixed with pale yellow scales, light brown on inner surface, except tarsus mixed with black scales.

Male genitalia ( Fig. 20 ). Socius with brachia bent inward, with a few setae on outer margin, asymmetrical: left brachium longer than right brachium, inflated distally, bent inward by almost a right angle; right brachium uniformly slender. Tegumen sub-trapezoidal. Valva asymmetrical, with setae ventrally; left valva with distal half dilated elliptically; right valva slightly widened before apex, bent inward. Saccus 2 length of left valva, narrowed towards rounded apex.Anellus narrowed towards truncate apex dorsally, narrowly band-shaped ventrally. Aedeagus cylindrical; vesica with wrinkles.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific epithet of the new species is derived from the Latin afflatus, referring to the left valva with distal half dilated in the male genitalia.
