Holotype : ♂ , broad-leaf bamboo ( Sasa borealis ) patch beside creek ( 35°26 ʹ 49 ʺ N , 126°50 ʹ 50 ʺ E , alt. 132 m ), Bukha-myeon , Jangseong-gun , Jeollanam-do , 12 May 2006 , B. K. Seo . Paratypes : 16♂ ♂ , 1$, same data as holotype ; 1♂ , 1$, mixed forest ( 35°27 ʹ 56 ʺ N , 126°52 ʹ 37 ʺ E , alt. 376 m ), Bokheung-myeon , Sunchang-gun , Jeollabuk-do , 19 May 2007 , B. K. Seo . Etymology. The specific name is a Latin adjective “ parva ” (small), referring to the body size of the type specimens. Diagnosis. The new species resembles T. silvicultrix Saito, 1980 in the prolateral tibial apophysis of male palp, but different from the latter by the dorsal tibial apophysis, the embolic division of male palp, and female genitalia. The new species is also similar to T. corsica ( Simon, 1884 ) in the genitalia, but easily distinguished from the latter by the posterior spermathecae of female and the embolic division of male palp ( Fig. 10 GK, N).
