INTRODUCTION 
Among the gekkonid genera occurring in China, Gekko is the largest group with the widest 
range of distribution. Six species and two subspecies have hitherto been known for the genus from 
China (Stejneger, 1932; Chen, 1969). During 1975 to 1980, Department of Biology, Nanjing 
Normal College collected 1637 specimens of Gekko from Hebei (Hopei), Shanxi (Shansi), 
Shaanxi (Shensi), Shandong (Shantung), Henan (Honan), Jiangsu (Kiangsu), Anhui (Anhwei), 
Hubei (Hupeh), Sichuan (Szuchuan), Zhejiang (Chekiang), Fujian (Fukien), Jiangxi (Kiangsi), 
Hunan (Hunan), Guizhou (Kweichow), Yunnan (Yunnan), Guangdong (Canton), Hainan 
(Hainan)*, and Guangxi (Kwangsi) Provinces. Several specimens were also collected from 
Guizhou Province by Department of Biology, Zunyi Medical College. While studying these speci- 
mens, three new species were discovered. On the other hand, Gekko japonicus hokouensis from 
Yanshan (Chainshan) Prefecture, Jiangxi Province, proved to represent a good species. Conse- 
quently, ten Gekko species** are presently recognized from China as follows:
