( Figs 5–6 ) Etymology. The species is named after Zhang Shun, one of the 108 outlaws in the classical Chinese literature Outlaws of the Marsh ; noun in apposition. Diagnosis. The male of the new species is similar to that of L. chishuiensis by the largest dorsal spine serrated, but it can be distinguished by having the strong spines on the retrolateral tibial apophysis extended further than the tip of the retrolateral tibial apophysis ( vs. almost equal).
