Li and Z. Chen leg. Paratypes (IZCAS): 4♂ and 6♀, same data as holotype.  Other material examined. 5♀ (molecular vouchers, IZCAS), same data as holotype.  Etymology. The species epithet refers to the type locality; noun.  Diagnosis.  Pinelema huoyanZhao & Li, sp. n. differs from all other congeners of P. bailongensisspecies group by following combination of characters: eyeless (Figure 7A), embolus with small distal-retrolateral apophyses (arrow in Figure 6D), and Esl/El ratio 0.72-0.78 (n = 5, mean: 0.76). In other congeners, combination of relative characters are either eyeless and no apophyses, or eyes distinct and no apophyses, or eyes distinct and apophyses present, and Esl/El ratio 0.33-0.67.  Figure 6. Pinelema huoyanZhao & Li, sp. n., male.
