3.VIII 2011, 1♂ (Y. Qiao & G.X. Xue leg.).

NOTES. This species can be easily recognized by a pair of backward-bent processes on the top of the uncus of the male genitalia. Two subspecies are known (Evans, 1949: 446; Hsu et al., 2006: 333), viz. the nominotypical subspecies and Polytremis lubricans kuyaniana

(Matsumura, 1919). The former has been recorded from Guangdong, Hainan, Guangxi,

Yunnan, SE Tibet, India, Indo-China Peninsula, Malaysia and Indonesia, and the later has been known as distributed in Guizhou, Hunan, Hubei, Anhui, Jiangxi, Zhejiang, Fujian and

Taiwan. According to Evans (1949: 446), the two cell spots are usually connected in P.

lubricans lubricans, but separated in P. lubricans kuyaniana . After an examination of about

50 specimens from Tibet, Yunnan, Guizhou, Guangxi, Jiangxi, Fujian, Zhejiang, Anhui and

Henan, we found the distance between the cell spots is variable, and there is not a distinct geographic gap between the distributional ranges of these two subspecies, so P. lubricans kuyaniana may be merged into P. lubricans lubricans . But we are reluctant to draw the con-

clusion now, since more extensive material need to be examined in further study. Evans (1949:

446) listed Japan in the distribution of P. lubricans taiwana (= P. lubricans kuyaniana ), but this record is possibly based upon a misidentification of Zinaida pellucida (Murray, 1875)

(Chiba, pers. comm.).
