Cosmodesmus tamerlanus kansuensis O. Bang-Haas, 1933; Ent. Zeit, 47(11): 90; TL: ‘ Kansu mer. or., Tsinglingschan, Peilingschan’ [Qinling, S.E. Gansu, China] .

Graphium mathias Wang, Chen & Wang, 1990, Butt. Fauna Henan: 7, pl. 9, f. 12. [Nomen nudum, attributed to Oberthür]

Diagnostic characters: Smaller than the nominate subspecies, forewing length: male 33.5–39.0 mm (mean = 37.3 ± 1.6 mm, n = 17), female 39.0–40.0 mm (mean = 39.7 ± 0.6 mm, n = 3). Both wings narrower and slightly elongate, the 9 th black band of forewing reduced even before vein CuA 2 in both sexes, the subterminal double black bands obviously close to each other.

Distribution: Confined to the Qinling Mountains in S.E. Gansu, southern Shaanxi and western Henan prov- inces, China.

Phenology: Specimen records indicate the flight period mainly lasts from April to June, but also as late as August (syntypes). Whether this species is univoltine or bivoltine requires further investigation.

Host plant: Unknown. Probably a plant belonging to the family Lauraceae .
