Otacilia xuning Lin & Li , sp. nov. ( Figs 42 View Figure 42 , 48B View Figure 48 )

Etymology. The species is named after Xu Ning, one of the 108 outlaws in the classical Chinese literature Outlaws of the Marsh; noun in apposition.

Diagnosis. The new species is similar to O. curvata Jin, Fu, Yin & Zhang, 2016 by the longitudinal copulatory ducts being close together. However, the new species can be distinguished from O. curvata by the oval spermathecae ( vs. Csharped in O. curvata ).
