Type material.
China, Hainan: Holotype ♂, Bawangling (19.07N, 109.03E), 650 m, 7.IV.2008, leg. BB Hu & HY Bai, slide No. LJ17529. Paratypes (3♂): 1♂, Bawangling, 1000 m, 9.IV.2008, leg. BB Hu & HY Bai; 1♂, Hongxin, Yuanmen, Baisha, 430 m, 16.IV.2014, leg. TT Liu et al.; 1♂, Mt. Wuzhi, 738 m, 2.XI.2016, leg. X Bai et al.
Diagnosis.
The new species is similar to M. neargometra (Wang, 2003) in the male genitalia. It can be separated from the latter by the transtilla pointed at apex and the sacculus produced to a sub-rectangular process dorsoapically. In M. neargometra , the transtilla is rounded at apex and the sacculus is produced to a sub-triangular process dorsoapically ( Wang 2003: 202, fig. 9).
Description.
Adult (Fig. 16 View Figures 12–19 ). Wingspan 13.0-14.0 mm. Head with frons yellowish white mixed with blackish brown, vertex blackish brown. Labial palpus yellow; distal half of second segment mixed with dense black scales on outer surface, forming a black ring at apex; third segment mixed with dense black scales from distal half to before apex ventrally. Antenna blackish brown; scape mixed with yellow; flagellum annulated with yellow ventrally. Thorax and tegula blackish brown. Forewing blackish brown, tinged with pale yellow to yellow scales; median fascia yellow, with blackish brown scales medially, extending from basal 2/5 of costal margin obliquely outward to around tornus, widened posteriorly; costal spot yellow, inverted triangular, edged with sparse blackish brown scales, extending to outer margin of cell posteriorly; fringe blackish brown. Hindwing and fringe greyish brown. Legs yellow, with exception on ventral surface: fore coxa blackish brown; femora of fore- and midlegs with dense blackish brown scales, hind femur with sparse blackish brown scales; tarsi of fore- and midlegs blackish brown, yellow at apices of basal two and apical one tarsomeres, hind tarsus with basal three tarsomeres blackish brown except yellow apically; all tibiae blackish brown except yellow apically.
Male genitalia (Fig. 32 View Figures 28–35 ). Uncus broad at base, narrowed to rounded apex, with long setae mediolaterally. Tegumen narrowed medially; lateral arm narrowed anteriorly. Valva narrow at base, widened from base to basal 1/3, uniformly wide from basal 1/3 to pre-apex, rounded at apex; costa band-shaped, uniformly wide, reaching distal 1/3 of valva, with sparse long setae; transtilla heavily sclerotized, uniformly wide except pointed apically, joined by membrane medially; sclerotized fold from base of ventral margin extending to middle of valva, parallel with costa. Sacculus sub-quadrate, dorsoapically produced to a heavily sclerotized sub-rectangular process, densely setose, straight at apex, sinuate dorsally; sclerotized on dorsal and ventral margins. Saccus wide at base, slightly narrowed to rounded apex. Juxta arched. Phallus shorter than valva, widened medially; distal half membranous, with a curved slender belt as long as 2/5 length of phallus.
Female unknown.
Distribution.
Hainan (Baisha, Bawangling, Mt. Wuzhi).
Etymology.
The specific epithet is derived from the Latin apic - (adj., apical) and rectangulus (adj., rectangular), referring to the shape of the apical process of the sacculus.
