Type material. CHINA, Hainan: Holotype ♂, Hongkan (19.08°N, 109.50°E), Yinggeling , 540 m, 24.VII.2015, leg. QY Wang et al., slide No. YAH15408 ( NKU) GoogleMaps . Paratypes (3♂): 1♂, Hongkan, Yinggeling , 540 m, 17.VIII.2016, leg. QY Wang et al., slide No. LJ 17508; 2♂, Yinggezui, Yinggeling, 599 m, 30.VII–1.VIII.2017, leg. X Bai et al ( NKU) .
Diagnosis. The new species is similar to M. tamraensis Park, 2016 in the male genitalia, but can be distinguished by the sacculus longer than its median width and the triangular saccus shorter than the uncus; in M. tamraensis , the sacculus is shorter than wide, and the distally clubbed saccus is as long as the uncus ( Park & Park 2016: 486, fig. 4). It is also similar to M. ledongensis sp. nov. in the male genitalia, and the differences between them are stated in the diagnosis of the preceding species.
Description. Adult ( Fig. 18 View FIGURES 15–20 ). Forewing length 4.0‾ 4.5 mm.
Head yellow, vertex greyish black. Labial palpus yellow; first and second segments with dense greyish-black scales on outer surface, second segment with a greyish-black ring apically; third segment 2/3 length of second segment, with greyish-black scales medially. Antenna greyish black; scape yellow apically; flagellum ringed with yellow on ventral surface.
Thorax greyish black, yellow laterally; tegula with basal half greyish black, distal half yellow. Forewing greyish black, with orange-yellow scales at base; costal margin with inner yellow spot from basal 1/3 obliquely outward to posterior margin of cell, sub-rectangular, outer yellow spot from distal 1/4 crossing posterior angle of cell, inverted triangular; dorsal yellow spot represented by a yellow stripe extending from end to distal 1/4 of fold; fold with a rounded black spot at distal 1/4; cell with a black spot at middle, touching inner margin of inner yellow spot, with black spot below anterior and posterior angles respectively, surrounded by yellow scales; fringe greyish black, with a yellow basal line. Hindwing and fringe pale greyish brown. Legs yellow on dorsal surface; blackish brown on ventral surface except tibiae yellow apically, tarsi of fore- and midlegs yellow at apices of basal two and apical one tarsomeres, hind tarsus yellow at apex of each tarsomere.
Male genitalia ( Fig. 40 View FIGURES 37–42 ). Uncus slender, clavate, pointed at apex. Gnathos sclerotized laterally, right-angled posterolaterally, slender and straight distally. Tegumen widened medially, broadly concave medially on anterior margin; lateral arm narrowed anteriorly. Valva elongate rectangular, with dense long setae in distal 1/3; apex obliquely truncate outward, with a short spine at ventral corner; ventral margin convex and serrate in distal 2/3, with a spine at apex; costa narrow, straight, reaching apex of valva; transtilla absent. Sacculus sub-rectangular, longer than its median width, separated from valva distally; apex heavily sclerotized, with dense short setae, concave inward at anterior 1/3, with a short spine above concavity and a large digitate process below concavity; dorsal margin heavily sclerotized, forming a narrow edge; ventral margin straight. Saccus narrowed from wide base to pointed apex, shorter than uncus. Juxta weakly sclerotized, U-shaped, anteriorly narrow; lateral arm widely banded, with short conic process at anterolateral corner. Aedeagus slightly longer than valva, narrow basally, evenly wide medially, bifurcate distally: dorsal part bilobed distally, dorsal lobe short digitate, rounded at apex, ventral lobe longer, spineshaped; ventral part rounded at apex, with a short spine apically.
Female unknown.
Distribution. China (Hainan).
Etymology. The specific epithet is derived from the Latin rect - and costatus, referring to the straight costa.
