Diagnosis.
The new species can be distinguished from its congeners by the uncus with a tuft of long setae at apex, and by the elliptical corpus bursae full of dense denticles that form a conspicuous inverted U-shaped area. It is similar to M. latiunca sp. nov. in the male genitalia, but can be distinguished by the uncus dilated distally, the tegumen widened medially, and the saccus slightly shorter than the uncus; in M. latiunca , the uncus is not dilated distally, the tegumen is narrowed medially, and the saccus is longer than the uncus.
Description.
Adult (Fig. 10 View Figures 4–11 ). Wingspan 8.0-9.0 mm. Head black, vertex with yellow scales laterally. Labial palpus yellow; second segment with dense blackish brown in basal 2/3, with a blackish brown ring before apex; third segment nearly 2/3 length of second segment, with blackish brown scales medially. Antenna with scape yellow, mixed with blackish brown scales; flagellum blackish brown, ringed with yellow ventrally. Thorax greyish black, mixed with sparse yellow scales; tegula greyish black. Forewing greyish black, with a diffused yellow spot at base below costal margin; costal margin with two orange spots: first spot from basal 1/3 extending to middle of cell posteriorly, sub-rectangular, second spot triangular, from distal 1/4 extending obliquely to beyond anterior angle of cell posteriorly, with a blackish brown dot at middle anteriorly; cell with a black spot at basal 1/3, with two black spots near outer margin placed one above the other, with a large orange spot between them, small black dots on inside of yellow spot; plical spot black, rounded, bordered by orange-yellow spots on outside, placed at distal 1/3 of fold; dorsal spot orange, smaller, placed before end of fold; fringe greyish black, mixed with yellow basally. Hindwing and fringe greyish brown. Legs yellow, with exception on ventral surface: fore coxa blackish brown, tarsi of fore- and midlegs blackish brown, yellow at apices of basal two tarsomeres, hind tarsus blackish brown, yellow at apex of each tarsomere; all femora with dense blackish brown scales, tibiae blackish brown, yellow apically.
Male genitalia (Fig. 26 View Figures 20–27 ). Uncus wide at base, narrowed from base to basal 1/5, uniformly wide from basal 1/5 to basal 3/5, thereafter dilated elliptically, with a vertical semicircular sclerite near base; apex rounded, with a tuft of long setae. Gnathos weakly sclerotized laterally, just exceeding posterior margin of tegumen, invisible anteriorly. Tegumen widened medially; lateral arm narrow and short, shorter than median width, narrowed anteriorly. Valva triangular, narrow at base, widened to apex, with a small pad bearing several long setae at basal 1/3 on inner surface, with strong long setae distally; apex obliquely rounded, with a row of short setae arranged like a comb; costa narrow, lineate in distal half, with sparse long setae; ventral margin heavily sclerotized, forming a narrow band. Sacculus wide at base, slightly narrowed from base to apex; apex rounded, heavily sclerotized, covered with sparse setae. Saccus wide at base, narrowed to rounded apex; slightly shorter than uncus. Juxta slender, weakly arched. Phallus longer than valva, wide medially, with a large U-shaped sclerite distally.
Female genitalia (Fig. 38 View Figures 36–41 ). Papillae anales relatively short, rounded caudally, setose. Apophyses anteriores approximately 1/2 length of apophyses posteriores. Eighth sternal plate spiculate; posterior margin gently concave at middle, with long setae. Lamella antevaginalis trapezoidal. Ductus bursae membranous, narrower in posterior half, wide in anterior half, anteriorly with a round sclerotized area full of granules; ductus seminalis arising from middle of ductus bursae. Corpus bursae elliptical, slightly longer than ductus bursae, with dense denticles entirely, denticles larger from posterior 1/6 to middle, forming a conspicuous inverted U-shaped area.
Distribution.
Hainan (Bawangling, Jianfengling).
Etymology.
The specific epithet is derived from the Latin pectinalis (adj., comblike), referring to the valva with a row of setae along apex arranged like a comb.
