Holotype: ♂, Mt. Wuzhi , Wuzhishan, Hainan, China, ca. 800 m, 8.V.2023, Z. Liu leg. (will be deposited to CMNH).

Description: Male. ( Fig. 1 ) Antenna black with basal club and inner side of shaft dorsally white. Thirteen segments of nudum antennomeres present in ventral apiculus. Wings ground color dark brown. In addition to a small white spot in base of space 1b, forewing upperside with white hyaline spots situated in discal areas of spaces 1b to 3, subapical areas of spaces 4 to 8, and areas near end of cell. Spots in space 2 and cell larger and notably separated from each other. Subapical spots in spaces 4 and 5 prominent and adjacent to spots in spaces 6 to 8. Forewing underside generally similar to upperside but with extra fuzzy pale areas in basal and distal parts of space 1b. Hindwing upper side covered with dense ochreous hairs at base.A series of sparse orange markings in center and submargin of spaces 1 to 3 with a large spot outside cell. Markings on hindwing underside prominent with additional spots in middle of cell and base of space 7. Fringes deep brown on forewing and checkered on hindwing. Genitalia. ( Fig. 2 ) Vinculum slender, twice as long as saccus. Tegumen protruding posteriorly to form a pair of strong humps. Gnathos with elongated ventral parts, of moderate width, indistinctly spined distally. Uncus bifid and laterally fan-shaped with a straight posterior process. Valva with a rectangular base and triangular end. Harpe and ampulla integrated with distal part prolonged into a blunt end. Juxta curved in middle with bilateral parts expansive. Phallus robust and curved downwards with a hooked cornutus.

Diagnosis. This new species can be superficially distinguished from all the other species by:

(1) Presence of a basal and a distal white spot in space 1b on the forewing upperside.

(2) Absence of basal yellow striping on the hindwing underside.

(3) White spots in the central areas of the forewing are separated.

(4) Subapical spots in the forewing spaces 4–5 are prominent, adjacent to those in spaces 6–8.

In genitalia, this new species can be separated from C. aspersa with similar valva by:

(5) Distal end of valva gradually narrow, but the end is abruptly tapered in C. aspersa .

(6) Phallus is robust and curved downwards while it is slender and almost straight in C. aspersa .

Distribution. Hainan Is., China.

Etymology. The specific name is dedicated to Miss Qian-Han Liu, the daughter of the second author, who inspires him to engage in surveys on the butterfly fauna of Hainan.
