( Figs 70–71 , 73C–D ) Etymology. The species is named after Xuan Zan, a character in the classic Chinese novel Outlaws of the Marsh ; noun in apposition. Figure 74. Gushangzao pelorosus ( Zhu, 1998 ) comb. nov. , female, alive. Photo by Qianle Lu. Diagnosis. The male of the new species is similar to Y. mutilata (Bösenberg & Strand, 1906) (see Yoshida, 2002 ) by the needle-shaped embolus and the same shaped sperm duct. However, the new species can be distinguished from Y. mutilata by the conductor directed dorsally in ventral view ( vs. directed retrolaterally in ventral view). The female of the new species is similar to Y. castrata (see Yoshida, 2002 ) by the oval atrium. However, it can be distinguished by the primary and secondary spermathecae being equal in size ( vs. primary spermathecae about twice as large as secondary spermathecae). Description.

Similar to that of male. Epigyne ( Fig. 71 ). Epigynal plate oval. Atrium oval, copulatory openings inconspicuous, situated anteriorly. Copulatory and fertilization ducts connected to secondary spermathecae anteriorly, straight. Primary spermathecae membranous, as wide as secondary spermathecae, secondary spermathecae more sclerotized. Fertilization ducts directed at 12:00-o’clock-position from secondary spermatheca.
