Potanthus trachalus phoebe (Evans, 1934)

Fig. 4

MATERIAL EXAMINED. China: Henan Province, Sishan , Xixia County, 28.VIII 2011 ,

1♂ (FL: 14.5 mm) (Y. Qiao & G.X. Xue leg.).

DISTRIBUTION. China (Sichuan, S Gansu, SE Shaanxi, SW Henan, Anhui, Hubei,

Hunan, Jiangxi, Fujian).

NOTES. A good character for recognizing Potanthus trachalus is that the uncus is tapered toward a round point in dorsal view (Eliot, 1992: 591, fig. 400; Huang, 2002: 118, fig. 29).

This species is distributed from central and southern China westwards to India, through

Myanmar, Thailand, and Malay Peninsula to Indonesia. Five subspecies have been separated

(Evans, 1949: 376), three are known to China.

Evans (1949: 376) and Fan (2006: 154) recorded Potanthus trachalus phoebe from Yunnan and P. trachalus trachalus from Hainan; Chiba (2008: 344) also recorded the nominotypical subspecies in a check list of Hainan skippers. But Huang (2003: 40) considered the population from Yunnan as P. trachalus tytleri and that from Hainan as P. trachalus phoebe . More specimens from Yunnan and Hainan are needed in further study to clarify the distribution of these three subspecies in China.
