( Figs. 2 , 7 )

Type material. CHINA: Holotype ³, Mt. Wolong (19.46°N, 110.12°E), Tunchang County, Hainan Province, 126 m, 20.VI.2018, leg. Ping Liu, Xia Bai and Shuai Yu, slide No. BX 16381.

Paratype. CHINA: 1³, Yaxing, Nankai , Baisha County, Hainan Province, 312 m, 29.VII.2015, leg. Qingyun Wang, Suran Li and Mengting Chen, slide No. BX 15315 .

Diagnosis. The male genitalia are similar to those of H. tinctoria Meyrick, 1916 but can be distinguished by the subtriangular tegumen and indistinct neck of the valva; in H. tinctoria , the tegumen is quadrate and the neck of the valva is distinctly narrow and approximately half of the maximum width of the valva (Clark 1958: 428, fig. 3a). The male genitalia are also similar to those of H. spinoa Razowski, 2016 , but can be distinguished by the cluster of short spines at the middle of the ventral margin of the valva and the distal 0.33 widening to the rounded apex; in H. spinoa , the valva has four ventral spines at the distal 0.33 and is not widened distally ( Razowski, 2016: 218, fig. 21).

Description. Adult ( Fig. 2 ). Vertex grayish brown, frons pale brown. Antenna pale brown. Labial palpus grayish brown; second segment expanded distally; third segment short and thin, drooping. Patagium grayish brown; thorax grayish white mixed with blackish brown; tegula with anterior 0.33 blackish brown, posterior 0.66 grayish white mixed with grayish brown. Foreleg blackish brown, tibia grayish white at middle and apex, first, second and fifth tarsomeres pale brown at apex; midleg blackish brown, grayish white at middle and apex of tibia, as well as at apex of first to third and fifth tarsomeres; hindleg grayish white, tarsus grayish brown, each tarsomeres grayish white at apex.

Wingspan 9.0‒ 9.5 mm. Forewing ground color grayish white, mixed with brown and leaden gray; costa black- ish brown, with nine pairs of strigulae: basal three pairs gray, other pairs grayish white, striae below distal four pairs leaden gray, mixed with yellowish brown; blackish brown patch extending from basal 0.33 of dorsum outward to upper margin of discal cell at middle, indicating outer edge of basal patch; median fascia short, extending from middle of costa to upper margin of discal cell at distal 0.25, forming a subtrapezoidal blackish brown spot; tornal spot blackish brown mixed with yellowish brown, extending along inner margin of ocellus to near apex of M 2; ocellus leaden gray, transverse blackish brown stripe in middle, mixed with yellowish brown, narrowed to tornus; cilia grayish white mixed with blackish brown, subbasal line blackish brown. Hindwing and cilia gray.

Male genitalia ( Fig. 7 ): Tegumen subtriangular, rounded on posterior margin. Socius approximately 0.4 times length of tegumen, with sparse short setae. Valva with basal 0.66 subparallel, distal 0.33 widening to rounded apex, setose dorsoapically; basal excavation approximately 0.33 length of valva; costa slightly concave at middle; ventral margin with a cluster of short spines at middle and a large spine before apex; sacculus narrow; neck indistinct. Phallus broad at base, sharply narrowed to basal 0.33, then gradually narrowed to pointed apex, approximately 0.66 length of valva; cornuti consisting of several deciduous needlelike spines.

Female unknown.

Distribution. China (Hainan).

Etymology. The specific epithet is derived from the Latin prefix medi - and the Latin spinatus, referring to the clustered short spines at the middle of the valva ventrally in the male genitalia.
