Distribution. China (Fig. 212), France. Remarks. The epigyne resembles Molestia molestus (Tao, Li & Zhu, 1995) in having a similar reduced scape consisting only of the swollen proscapus, which has a very distinct anteromedian cleft (Fig. 209A–C). The scape is partly buried inside the epigynal cavity. Based on Types. Holotype ♀, CHINA, Yunnan, Lushui County, Yaojiaping, at Pianma Road 44.7 km, 25.97479°N, 98.71027°E, alt. 2516m, disturbed forest; dusting webs in understory, 19–20 May 2005, Charles Griswold leg. (CGY111). Paratypes: 9♀, same data as holotype (CGY111). Etymology. This epithet derives from the type locality. Diagnosis. The female of the new species can be distinguished from all other congeners by the spermathecae situated dorso-mesally, pointing towards each other and separated by a minimal distance of their diameter (Fig. 210A–C); epigynal plate posteriorly with broad lobes on each side (Fig. 210A–C).
