Embolus (E) inserted at approximately ten o’clock on tegulum, slender and flagelliform, angled across tegular tip, stretched proximally along membranous conductor, tip extending to one-third of tegulum. Conductor (C) area relatively small, approximately two-fifths the length of tegulum.
Female (Fig. 3 View Figure 3 G and H. Dimensions in mm) Total length 3.64; carapace 1.61 long, 1.14 wide; abdomen 2.03 long, 1.35 wide. Eye sizes and interdistances: AME 0.09, ALE 0.19, PME 0.07, PLE 0.07, AME-AME 0.05, AME-ALE 0.04, PME-PME 0.19, PME-PLE 0.09. MOQL 0.25, MOQA 0.23, MOQP 0.36. Sternum 0.87 long, 0.49 wide. Measurements of legs: I 2.65 (0.77, 1.10, 0.53, 0.25), II 2.79 (0.84, 1.15, 0.58, 0.22), III 2.52 (0.66, 0.98, 0.65, 0.23), IV 3.81 (1.25, 1.26, 0.94, 0.35). General characters as in female, but slightly larger in size and lighter in colour.
Epigyne (Fig. 3 View Figure 3 A-D). Epigynal plate distinctly longer than wide, anterior and lateral margin not delimited, posterior margin rebordered, heavily sclerotised and convex; spermathecae (SP) clearly visible through the tegument in ventral view. Two copulatory openings (CO) large, partly fused, situated at medial portion of epigynal plate posterior margin, anteriorly hidden by a hood. Hood (H) wider than 1/2 of epigyne width, heavily sclerotised, V or U-shaped. Hyaline copulatory ducts (CD) thin, ascending in parallel, the proximal half close together, the distal half widely separated and gently curved towards the bursae. Both spermathecae (SP) and bursae (BS) with smooth surfaces, the former anteriad and distinctly larger than the latter. Spermatheca shaped like a chicken egg, inside pigmented and sclerotised, the two spermathecae closely spaced. Bursae globular, separated by ca. 1.2 diameters.

Diagnosis
Clubiona jiugong sp. nov. resembles the other Clubiona zilla -group species by the similar habitus (tiny body with length not exceeding 4 mm), but is consistently separable by its genitalia. Male of the new species resembles that of C. hooda ( Dong and Zhang 2016: 7, figures 5-7 and 10-12) in having a dagger-shaped EPA and a flagelliform embolus, but can be recognised by the RTA distally bifurcate (Fig. 1 View Figure 1 C) (vs. RTA not branched in C. hooda ) and by the EPA originating from the prolateral portion of the tegulum, pointed to the retrolateral side (Fig. 1 View Figure 1 C, Fig. 2 View Figure 2 A and C-E) (vs. EPA originating retrolaterally and curved to the prolateral side). Females of C. jiugong sp. nov. can be easily distinguished from other members of the C. zilla -group, with the exception of C. zilla ( Ono 1986: 119, figures 6-8) by the hood represented by a transverse sclerotised plate (hoods represented by pairs of guide pockets in all other Clubiona zilla -group species) and differ from C. zilla by: (1) copulatory openings closely spaced and partly fused, situated at the medial portion of epigynal plate posterior margin (Fig. 3 View Figure 3 A and B) (vs. copulatory openings well separated by ca. 0.8 diameters, situated basolaterally in C. zilla ); (2) the proximal half of copulatory ducts close together (Fig. 3 View Figure 3 A and B) (vs. the proximal half of copulatory ducts well separated by more than 4 diameters); (3) spermatheca oval and large, its diameter nearly 1/2 of epigynal width (Fig. 3 View Figure 3 C and D) (vs. spermatheca globular and small, its diameter slightly less than 1/5 of epigynal width).
Etymology
The species name is derived from the name of the type locality; noun in apposition.
Distribution
Known from the Mt. Jiugong, Hubei Province, China (Fig. 1 View Figure 1 A).
Biology
The holotype of C. jiugong sp. nov. was obtained from foliage in a bush close to a mountain road in the core zone of Jiugong mountain range.
