Type material.
China, Hainan: Holotype ♂, Datian (19.11N, 108.79E), Dongfang, 56 m, 7.VI.2018, leg. P Liu et al., slide No. LJ17553.
Diagnosis.
The new species is similar to M. leishana (Wang, 2006), M. stica (Wang, 2006) and M. puncticulata sp. nov. in the forewing patterns. It can be distinguished from M. leishana and M. stica by the uncus longer than the saccus and the phallus without sclerotized belts distally; in M. leishana (Wang, 2006) ( Wang 2006a: 131, fig. 216) and M. stica (Wang, 2006) ( Wang 2006b: 25, fig. 15), the uncus is shorter than the saccus and the phallus has sclerotized belts distally. It can be separated from M. puncticulata by the uncus tapered from base to apex, the relatively narrower and shorter saccus ca. 3/5 the length of the uncus, and the phallus without cornutus; in M. puncticulata , the uncus is widened from base to middle, thereafter narrowed to apex, the saccus is almost as long as the uncus, and the phallus has a strong cornutus.
Description.
Adult (Fig. 17 View Figures 12–19 ). Wingspan 14.5 mm. Head yellow. Labial palpus yellow; second segment with blackish brown scales dorsally, forming a dark dot before apex; third segment with sparse blackish brown scales dorsally. Antenna yellow, flagellum annulated with brown (worn). Thorax yellow (worn); tegula yellow, blackish brown at base. Forewing yellow, with blackish brown scales; costal margin with blackish brown dot at base, beyond middle and at distal 1/3 respectively; cell with a blackish brown spot beyond middle and at outer margin respectively; plical spots blackish brown, small, rounded; terminal dots running from distal part of costal margin along termen to tornus, evenly spaced; fringe yellow. Hindwing and fringe grey. Legs yellow, with exception on ventral surface: fore- and midlegs blackish brown, tibia of midleg yellow apically, tarsus of midleg yellow at apex of each tarsomere, hindleg covered with blackish brown scales.
Male genitalia (Fig. 33 View Figures 28–35 ). Uncus conic, wide at base, distinctly tapered from base to apex, with a single long seta at basal 1/3 laterally. Tegumen slightly widened medially; lateral arm uniformly wide, obtuse anteriorly. Valva with basal 1/3 narrow, wide and subparallel medially, slightly narrowed from distal 1/5 to rounded apex, setose, with a densely setose pad at base; ventral margin weakly sclerotized, concave basally; costa with basal half uniformly wide, distal half narrowed to before apex; transtilla short, not meeting medially. Sacculus wide at base, narrowed from base to rounded apex; distal 1/3 heavily sclerotized, setose, overlapped with an ovate plate; ventral margin heavily sclerotized from base to distal 1/3, forming a wide band, with long setae. Saccus ca. 3/5 length of uncus, wide at base, narrowed from base to rounded apex. Juxta U-shaped; lateral lobe slender. Phallus approximately 4/5 length of valva, with lineate ridges distally; cornutus absent.
Female unknown.
Distribution.
Hainan (Dongfang).
Etymology.
The specific epithet is derived from the Latin conicus (adj., conic), referring to the shape of the uncus in the male genitalia.
