Anyphaena treecko Lin & Li , sp. nov. ( Figs 9A–C , 10A–B , 14I–J )

Diagnosis. Male of A. treecko Lin & Li , sp. nov. is similar to A. xiushanensis Song & Zhu, 1991 in having a similarly shaped MA, C, and RTA but can be distinguished by the RTA which narrows toward the terminus and has an obvious bifurcation (vs. terminus extended and bifurcation inconspicuous in A. xiushanensis ), and the cymbial apophysis is well developed, triangular (vs. bifurcated in A. xiushanensis ). Females are similar to A. xiushanensis by the shape of the epygine, but in A. treecko Lin & Li , sp. nov., the epygine is anteriorly narrow and flat (vs. blunt in A. xiushanensis ) and the CDs in A. treecko Lin & Li , sp. nov. are narrow.

Epigyne ( Figs 10A–B ) longer than wide, triangular; COs inconspicuous; CDs almost straight. AG distinct, at middle of CDs. S inconspicuous, oval.

Material examined. Holotype ♂, China: Hainan, Changjiang County, Bawangling, Dongsizhan (19.0495°N, 109.1157°E), 23 April 2009, leg. Guo Tang (IZCAS-Ar442404) . Paratypes. 2♀ (IZCAS-Ar42405–Ar42406), same data as holotype .

Distribution. Known only from the type locality.

Etymology. The species is named after Treecko, a fictional character from Pokémon Emerald that lives in the forest, as does this new species; noun (name) in apposition.
