Diagnosis.

This species is similar to H. hatanensis (Figs 2 B, D, F, H View Figure 2 , 6 View Figure 6 – 8 View Figure 8 ), but differs by the dwarf tegular sclerite vs. large and almost square; the short, strong and flat terminal apophysis vs. long and crooked; the wide and short subterminal apophysis vs. long and thin; median apophysis not bifurcate and the end bent to conductor vs. bifurcate, ventral branches curved, dorsal branch straight and pointed (Figs 2 G View Figure 2 , 3 A, B View Figure 3 , 4 C – F View Figure 4 , 5 View Figure 5 ); the arc-shaped copulatory openings, located on the anterior position of the septum vs. located below the septum; and the width of spermathecal head greater than the width of spermathecal stalk vs. width of spermathecal head almost the same as the width of spermathecal stalk (Figs 3 C, D View Figure 3 , 4 G, H View Figure 4 ).

Redescription.

Males total length 7.65–10.19. One male (Figs 1 B View Figure 1 , 4 A View Figure 4 , from Dongqing Lake) total length 7.65, carapace 3.72 long, 3.69 wide; opisthosoma 4.11 long, 2.01 wide. Eye sizes and interdistances: AME 0.20, ALE 0.14, PME 0.35, PLE 0.33; AME – AME 0.10, AME – ALE 0.05, PME – PME 0.26, PME – PLE 0.31. Clypeus height 0.17.

Palp (Figs 2 G View Figure 2 , 3 A, B View Figure 3 , 4 C – F View Figure 4 , 5 View Figure 5 ). Tip of cymbium 3 times shorter than cymbium; length / width ratio c. 1.7. The end of terminal apophysis short, strong and flat, subterminal apophysis membranous, as long as terminal apophysis. Median apophysis vertical, concave in lateral view. Tegular sclerite strongly sclerotized and dwarf. Embolus long and whip-like, smoothly rounded, slightly bent near tip, it makes almost whole circle, partly hidden by tegular ridge and median apophysis, base of embolus located in position of 2 o’clock.
