MQ Yang & GE Lee ; Guangxi: 1♂, Yangmeiao, Huanjiang County, Hechi City , 1180 m, 25.VII.2015, leg. MQ Yang & GE Lee ; Hainan: 1♂, Jian-fengling, Ledong County, 770 m, 29. V .2015, leg. PX Cong et al ( NKU).

Diagnosis. The new species is similar to M. tamraensis Park, 2016 in the forewing pattern, but can be distinguished by the uncus dilated and rounded apically, the valva rounded apically, and the sacculus with a large semicircular process above ventral corner; in M. tamraensis , the uncus is narrowed to acute apex, the valva is truncate apically, and the apically concave sacculus has two small triangular processes ( Park & Park 2016: 486, fig. 4).

Description. Adult ( Fig. 17 ). Forewing length 5.0 mm.

Head greyish black, tinged with yellow. Labial palpus greyish black; second segment yellow on basal half; third segment shorter than second segment, yellow apically. Antenna greyish black on dorsal surface, yellow on ventral surface.

Thorax and tegula blackish grey. Forewing blackish grey, with yellow spots; costal margin with inner yellow spot placed before middle, rounded, outer yellow spot at distal 1/4, inverted sub-triangular; fold with a black spot at basal 2/3, edged with yellow scales; cell with a black spot at basal 3/5, bordered by a yellow spot on outer margin, with a second black spot near outer margin, edged with yellow scales on inner side; fringe blackish grey. Hindwing and fringe blackish grey. Legs yellow; on ventral surface, fore coxa mixed with blackish-grey scales, fore tarsus blackish grey except yellow at base of basal tarsomere and at apices of basal two tarsomeres, tarsi of mid- and hind-legs blackish grey except yellow at base of basal tarsomere and at apex of each tarsomere, all femora with blackishgrey scales, all tibiae blackish grey except yellow apically.

Male genitalia ( Fig. 39 ). Uncus wide at base, narrowed to basal 1/4; distal 3/4 slenderly clavate, slightly dilated distally, rounded at apex. Gnathos sclerotized laterally, almost right-angled posterolaterally, slenderly straight downward to posterior 2/5 of tegumen. Tegumen distinctly widened medially, nearly 3.0 times as wide as lateral arm; lateral arm narrowed anteriorly, curved inward before apex. Valva parallel-sided from base to apex, length nearly 3.0 times of width; apex rounded, with dense long setae; ventral margin heavily sclerotized, with a long spine at pre-apex; costa straight, reaching apex of valva, with short setae; transtilla wide basally, slender distally, narrowed and joined medially. Sacculus sub-rectangular, shorter than wide, not separated from valva; apex with a sclerotized edge, produced to a large setose semicircular process above ventral corner. Saccus straight, clubbed, parallel to before rounded apex, nearly as long as uncus. Juxta narrow, U-shaped. Aedeagus longer than valva, basal half sclerotized, distal half membranous, with a heavily sclerotized, slenderly ribbon; apex with two large sclerites: one U-shaped, the other slightly curved.

Female unknown.

Distribution. China (Guangxi, Guizhou, Hainan).

Etymology. The specific epithet is derived from the Latin parallelus, referring to the parallel-sided valva in the male genitalia.
