Figs 10–12 Type material. Holotype : ♂ , CHINA : Yunnan : Xishuangbanna , Mengla County , Menglun Town , Menglun Nature Reserve , Lvshilin Forest Park , Limestone tropical seasonal rain forest ( N21º54.555' , E101º16.860' , 615 m ), 29 November 2009 , G. Tang and Z.Y. Yao (Tang-Yao_No.32). Paratype : 1 ♀ , same data as holotype . Etymology. The specific epithet is taken from the Latin word lumbricus (earthworm), referring to the embolus earthworm-shaped, noun in apposition. Diagnosis. The general appearance of this new species is much similar to that of Indoxysticus minutus (Tikader, 1960) . However, this species is different from Indoxysticus minutus by: the larger body size and the epigyne without transverse hood (cf. Benjamin and Jaleel 2010: 162 , figs 3–4, 8–15), and it is placed in this genus provisionally. FIGURE 10. Indoxysticus lumbricus sp. nov. , holotype from Xishuangbanna.
