Diagnosis.

Pinelema huoyan Zhao & Li, sp. n. differs from all other congeners of P. bailongensis species 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.

Description.

Insemination duct with a membranous tube (Figure 8C); receptacle as wide as insemination duct, U-shaped, slightly swollen at end (Figure 8C).

Variation.

In 4♂ paratypes: El/Bl ratio 1.38-1.43, Esl/El ratio 0.72-0.78.
