Diagnosis.
This species is similar to H. cereipes (L. Koch, 1878) (Figs 2 A, C, E, G, 3 – 5), but differs by the tall and almost square tegular sclerite vs. dwarf in H. cereipes; the long and crooked terminal apophysis vs. short, strong and flat; the long and thin subterminal apophysis vs. wide and short; the bifurcate median apophysis, ventral branches curved, dorsal branch straight and pointed vs. not bifurcate, end bent to conductor (Figs 2 H, 6 A, B, 7 C – F, 8); the crack-shape copulatory openings and located below of the septum (vs. arc-shaped, located on the anterior position of the septum); and the width of spermathecal head almost the same as the width of spermathecal stalk (vs. width of spermathecal head greater than the width of spermathecal stalk) (Figs 6 C, D, 7 G, H).
Description.
Males total length 7.52–10.36. One male (Figs 1 D, 7 A, from Qiemo County) total length 7.52: carapace 3.84 long, 2.73 wide; opisthosoma 3.82 long, 2.04 wide. Eye sizes and interdistances: AME 0.20, ALE 0.14, PME 0.36, PLE 0.32; AME – AME 0.13, AME – ALE 0.05, PME – PME 0.24, PME – PLE 0.30. Clypeus height 0.18. Leg measurements: I 11.82 (3.20, 4.03, 2.73, 1.86); II 11.52 (3.18, 3.81, 2.66, 1.86); III 11.58 (3.04, 3.55, 3.24, 1.75); IV 15.84 (4.00, 4.74, 4.83, 2.23).
Palp (Figs 2 H, 6 A, B, 7 C – F, 8). Cymbium c. 1.9 times longer than wide. The end of terminal apophysis curving, subterminal apophysis thin and membranous, shorter than the length of terminal apophysis. Median apophysis vertical and bifurcate, concave in lateral view. Tegular sclerite tall and almost square. Embolus long whip-like, smoothly rounded, slightly bent near tip, making almost whole circle, partly hidden by tegular ridge and median apophysis, base of embolus located in position of 2 o’clock. Conductor membranous.
Females total length 8.01–13.21. One female (Figs 1 C, 7 B, from Qiemo County) total length 8.01: carapace 4.03 long, 2.75 wide; opisthosoma 4.04 long, 2.45 wide. Eye sizes and interdistances: AME 0.23, ALE 0.15, PME 0.35, PLE 0.32; AME – AME 0.10, AME – ALE 0.04, PME – PME 0.27, PME – PLE 0.32. Clypeus height 0.19. Leg measurements: I 10.74 (3.05, 3.66, 2.29, 1.74); II 10.25 (2.88, 3.50, 2.20, 1.67); III 10.60 (2.90, 3.41, 2.63, 1.66); IV 14.62 (3.76, 4.55, 4.30, 2.01).
Epigyne (Figs 6 C, D, 7 G, H). Copulatory openings crack-shaped and located below of the septum. Spermathecal heads slightly inflated, approaching the anterior margins of spermathecal stalks. Spermathecal stalks as wide as heads. Accessorial gland arc-shaped, with a small and spherical head. Fertilization ducts small, crescent-shaped.
Distribution.
China (Xinjiang, Qinghai, Ningxia and Inner Mongolia) (Fig. 9).
Remarks.
Sample collected from the type locality of H. jartica contains specimens of both sexes. Comparison of these specimens with illustrations and descriptions of the H. jartica female and male of H. hatanensis reveals no differences, and therefore, we synonymized these names. The distance between the type localities is about 140 km. Although two species were described in the same paper, we consider H. hatanensis as the senior synonym because of page priority, and also because males have more diagnostic characters than females.
