Holotype: male, CHINA, Hainan province, Baisha Li Nationality Autonomous County, Yinggeling Natural Reserve, 109°50′90.78″ E 19°09′ 70.39″N, altitude 470 m, 30-V-2018, leg. Shi-fang Mo and Fuhong Wei. Paratype: 1 male. Same label as holotype. Diagnosis. H. hainana is characterized by the forewing ground color yellowish grey and the yellowish brown oblique submarginal line and the wing without darkish shade distal to medial band and the vaguely visible reniform stigma and the dense black dots of hindwing. In male genitalia, the valva is narrow flake-shaped, the saccular process is long and thick and slightly curved, especially, the right process with a slender process on the middle part of left side, the vesica with a long, curved and needle-shaped process. Externally, H. hainana sp. nov. is similar to H. butleri (Leech), but the ground color is paler in H. hainana; the submarginal line of forewing and the medial line of hindwing are both wider in H. hainana than in H. butleri; the color of the submarginal line is yellowish brown in H. hainana, and in H. butleri, the color of the submarginal line is blackish brown; the hindwing without discal spot in H. hainana, the discal spot on hindwing is well expressed in H. butleri. In male genitalia, valva with blunt circle distal end in H. hainana, valva with narrow distal end in H. butleri; the saccular process is robust, curved and thick in H. hainana, in H. butleri, saccular process long and stick-straight; the vesica with a long, curved and needle-shaped process in H. hainana, a membranous process and a long, tubular process on vesica in H. butleri. H. hainana new species is also similar to H. pseudobutleri sp. nov. and the differences between them are mentioned above. Description. Male. Length of forewing 24 mm. Head: antennae filiform, brownish grey; labial palpus brownish. Thorax: brown, tegulae yellowish, abdomen dorsally covered with short greyish hair; apex of forewing pointed and slightly falcate, termen convex from vein M 2 to vein Cu 2; forewing ground color yellowish grey, densely covered with numerous black scales; antemedial line black and irregular, extending from costa to cell; medial line black and obscure, extending from costa to vein R 5 and followed by a vaguely ring-like reniform stigma at posterior portion of discoidal cell; orbicular stigma black, dot-like and obscure; postmedial line black and obscure, extending from costa to vein R 4 and nearly parallel to the dorsum; submarginal line yellowish brown, thick and straight, extending from apex to median of dorsum, and a darker shade present exterior to the submarginal line; an obscure whitish line flanked inwards of the submarginal line. Hindwing ground color as forewing at posterior two thirds, greyish at costal and subcostal area; medial line yellowish brown and thick, extending from subcostal area to vein 3A, and inwardly flanked by a vestigial greyish line. Male genitalia. Uncus long and slender, curved at basal part. Tegumen short and broad, triangular. Saccus long and broad. Transtilla n-shaped, consisting of two inwardly curved lobes. Juxta H-shaped, broad, consisting of two inwardly curved lobes. Valvae long lamellar-shaped. Sacculus strongly sclerotized, left saccular process thick thumb-like, slightly curved outwards; relatively, right saccular process also thick and with a slender process on the middle part of left side. Aedeagus robust, vesica with a long, curved and needle-shaped process. Female. Unknown. Distribution. At present this species is only known to occur in China: Baisha Li Nationality Autonomous County at present. Etymology. The specific name hainana is derived from its type locality.
