description: <i>Anyphaena tibet</i> Lin &amp; Li, sp. nov. (Figs 7A–C, 8A–B, 13B, 14G–H) Diagnosis. Males of <i>A. tibet</i> Lin &amp; Li, <b>sp. nov.</b> are similar to those of <i>A. wuyi</i> Zhang, Zhu &amp; Song, 2005 and <i>A. rhynchophysa</i> in having a similar C and RTA but can be distinguished by the extended terminus of the MA (<i>vs.</i> narrowing toward terminus in <i>A. wuyi</i> and <i>A. rhynchophysa</i>), the width/length ratio of the vRTA is 0.5 (<i>vs.</i> 0.25 in <i>A. wuyi</i> and 0.33 in <i>A. rhynchophysa</i>), and the length ratio of the dRTA to the vRTA is almost 1:1 (<i>vs.</i> 0.33 in <i>A. wuyi</i> and <i>A. rhynchophysa</i>). Females are similar to <i>A. wuyi</i> and <i>A. rhynchophysa</i> by the convoluted CDs, but in <i>A. tibet</i> Lin &amp; Li, <b>sp. nov.</b>, the base of the COs is not enlarged (<i>vs.</i> enlarged base in <i>A. wuyi</i> and <i>A. rhynchophysa</i>) and the CDs are not spiraled in <i>A. tibet</i> Lin &amp; Li, <b>sp. nov.</b> (<i>vs.</i> two spirals in <i>A. wuyi</i> and one in <i>A. rhynchophysa</i>).
