Type material.
China, Hainan: Holotype ♂, Yinggezui (19.05N, 109.56E), Yinggeling, 599 m, 30.VII.2017, leg. X Bai et al., slide No. ZXJ18430. Paratypes (2♂): 1♂, 31.VII.2017, other same data as holotype; 1♂, Bawangling, 146 m, 16.VIII.2017, leg. X Bai et al.
Diagnosis.
The new species can be distinguished from its congeners by the uncus with several long stout setae distally and the valva with a row of short setae arranged like a comb apically. It is similar to M. pectinalis sp. nov., and the differences between them are stated in the diagnosis of the latter species.
Description.
Adult (Fig. 9 View Figures 4–11 ). Wingspan 8.0-10.0 mm. Head greyish brown. Labial palpus yellow; first and second segments with dense blackish grey scales; second segment with two indistinct blackish brown rings in distal half; third segment shorter than second segment, with scattered blackish grey scales. Antenna yellow; scape with dense greyish black scales dorsally; flagellum annulated with blackish grey on dorsal surface. Thorax and tegula blackish grey. Forewing broad lanceolate, apex narrowly rounded; ground color blackish grey, with scattered black scales, with a rounded yellow spot at base below costal margin; costal margin with median yellow spot rectangular, from basal 2/5 extending obliquely outward to before posterior margin of cell, distal yellow spot elongate elliptical, from distal 1/4 extending to anterior angle of cell; cell with black spot at ca. basal 2/3 and at posterior angle respectively, edged with yellow scales; plical spot black, edged with yellow scales; dorsal yellow spot at end of fold, smaller; fringe blackish grey. Hindwing and fringe pale greyish brown. Legs greyish yellow; on ventral surface, foreleg mixed with greyish brown on coxa, tarsi of fore- and midlegs greyish brown, yellow at apices of basal two tarsomeres, hind tarsus greyish brown, yellow at apex of each tarsomere; all femora mixed with greyish brown scales, tibiae greyish brown except yellow apically.
Male genitalia (Fig. 25 View Figures 20–27 ). Uncus wide at base, narrowed from base to basal 2/3, outer margin convex; distal 1/3 uniformly wide except narrowly rounded apex, with several stout setae. Gnathos sclerotized laterally, membranous anteriorly. Tegumen narrowed medially; lateral arm uniformly narrow, rounded anteriorly. Valva sub-triangular, narrow at base, widened to rounded apex; apex with a row of short setae arranged like a comb, running from pre-apex of costa along apex to ventroapex, obliquely rounded; ventral margin heavily sclerotized, with a crescent sclerite at base; costa straight, with sparse setae. Sacculus wide at base, slightly narrowed to obtuse apex; apex heavily sclerotized, forming a sclerotized band. Saccus slender, slightly longer than uncus, wide at base, narrowed from base to narrowly rounded apex. Juxta broadly U-shaped; lateral lobe short. Phallus longer than valva, tubular; cornutus absent.
Female unknown.
Distribution.
Hainan (Bawangling, Yinggeling).
Etymology.
The specific epithet is derived from the Latin latus (adj., broad) and the Latin term uncus (n., uncus), referring to the basally wide uncus.
