Material examined. – 2 males, 1 female ( HNU), Nanyue (27°05'N 112°19'E), Hunan Province, China, coll. G. Tang, P. Hu and Q. Wang, 3 May 2007 ; 1 female ( HNU), Xiaxiang, Tongdao County (26°03'N 109°17'E), Hunan Province, China, coll. C. Yin, 2 Jun.1996 ; 2 females ( HNU), Mujiao Township , Tongdao County, coll. X. Peng & Y. Zhang, 4 Jun.1996 ; 1 female ( HNU), Linkou Township , Tongdao County, coll. X. Peng & Y. Zhang, 6 Jun.1996 ; 1 male, 1 female (IZCAS-Ar9378, Ar 9379), Daoxian County (25°11'N 111°12'E), Hunan Province, China, coll. L. Gong, May.1984 ; 1 male, 1 female (IZCAS-Ar9380, Ar 9381), Tiantong Park (121°15'N 29°17'E), Ningbo City , Zhejiang Province, China, Jun.1990 ; 1 male (IZCAS-Ar9382), Yujiaping, Mountain Longxi , Jiangle County (117°05'N 26°11'E), Fujian Province, coll. Y. Han, 11 Apr.1991 .

Description. – Male palp with a spatulate VTA and 5 macrosetae at tibial apex; conductor axe shaped, apically curved; sperm ducts visible, embolus needle like, combined with a median apophysis basally, which can be observed after expanding for half an hour in lactic acid ( Fig. 4C, F ). Epigyne with a pair of sclerotized plates posteriorly; copulatory ducts short; spermathecae with 2 oval chambers.

Diagnosis. – This species is similar to E. ganxiensis (Yin, Peng & Kim, 1999) , the differences are discussed in the “diagnosis” of E. ganxiensis . The male is similar to E. longipalpis Thorell, 1877 , in the long palpal tibia, but can be separated from the latter by: the tibia with 2 apophyses (only with one in E. longipalpis ).

D i s t r i b u t i o n. – C h i n a (H u n a n, Z h e j i a n g, F u j i a n Provinces).

Remarks. – The male palp of Cupa gongi has a spatulate VTA and a row of macrosetae, the epigyne with a pair of posterior sclerotized plates, which are the typical diagnostic characters of the genus Epidius . Cupa gongi Song & Kim, 1992 , should be transferred to the genus Epidius as E. gongi (Song & Kim, 1992) , new combination. Philodromus longitibiacus Yin, Peng & Kim, 1999 , was firstly placed under the spider family Philodromidae . After examined both type specimens of Philodromus longitibiacus and Cupa gongi , it is found that Philodromus longitibiacus actually is a junior synonym of Epidius gongi (Song & Kim, 1992) .
