( Figs. 3 A–J, 7)

Philodromus ganxiensis Yin, Peng & Kim, 1999: 356 , Fig. 2 A–G (types in HNU, examined)

Material examined. – 2 males, 3 females ( HNU), Ganxi Township , Tongdao County (26°03'N 109°17'E), Hunan Province, China, coll. C. Yin, X. Peng and Y. Zhang, 1 Jun.1996 .

Description. – Male palp with a spatulate VTA and 6 macrosetae in a row at tibial apex, conductor transparent, twisted and concave at apex; embolus slender, apically hidden under the conductor. Epigyne with a pair of spatulate sclerotized plates posteriorly; copulatory openings slit like, copulatory ducts complexly twisted; spermathecae curved in n-shape.

Diagnosis. – This species can be separated from E. gongi (Song & Kim, 1992) by: the atrium slit-shaped laterally (pit like medially); the ratio of length of palpal tibia to palp = 1.2 (5.0 in E. gongi ).

Distribution. – China (Hunan).

Remarks. – The species was firstly placed under the spider family Philodromidae . However, the male palp has a spatulate VTA and a row of macrosetae, which are the typical diagnostic characters of the genus Epidius of family Thomisidae . Philodromus ganxiensis Yin, Peng & Kim, 1999 , should be transferred to the genus Epidius as E. ganxiensis (Yin, Peng & Kim, 1999) , new combination.
