Diagnosis.
Yunguirius duoge sp. nov. resembles Y. terebratus by having rectangular posterior epigynal sclerite, subrounded atrium and dumbbell-shaped spermatheca at its first half. However, it can be distinguished from Y. terebratus as follows: 1) posterior margin of the epigyne narrow and pointed in the middle (Fig. 2A View Figure 2 ) in Y. duoge sp. nov., but flat (fig. 28 in Peng and Wang 1997) in Y. terebratus ; 2) epigynal folds banded (Fig. 2A View Figure 2 ) in Y. duoge sp. nov., but dentiform (fig. 28 in Peng and Wang 1997) in Y. terebratus ; 3) anterior copulatory duct close to each other (Fig. 2B View Figure 2 ) in Y. duoge sp. nov., but lapped (fig. 29 in Peng and Wang 1997) in Y. terebratus ; and 4) stalk of spermatheca extending laterally (Fig. 2B View Figure 2 ) in Y. duoge sp. nov., but extending anteriorly (fig. 29 in Peng and Wang 1997) in Y. terebratus .
