Etymology. The specific name is a patronym after Guo Zheng, collector of several specimens examined in this study; name in genitive case. Diagnosis. Clubiona zhengi sp. nov. can be easily distinguished from all known congeners by the combination of the following characters: male palpal tibial with two apophyses ( Fig. 11B ); retrolateral tibial apophysis laminar broad, flat and with a straight apical margin ( Fig. 11B ); ventral tibial apophysis finger-shaped, elevated from a pit ( Fig. 11B ); female epigynal plate with an atrium ( Figs 12 A–B). Description. Male ( holotype ): Total length 2.84; prosoma 1.14 long, 0.71 wide; opisthosoma 1.65 long, 0.83 wide. Prosoma ( Figs 12 E–F), ovoid in dorsal view, ocular region slightly narrowed, widest between coxae II and III; in profile slightly higher just behind ocular area, gradually sloping posteriorly; integument smooth, clothed with numerous short fine hairs. Carapace yellowish, without distinct color pattern; longitudinal fovea reddish. Chelicerae protruding and light brown, with four promarginal and three retromarginal teeth. Labium and endites orange, longer than wide. Sternum orange-yellow. Eyes: AER slightly recurved, PER wider than AER and slightly procurved in dorsal view. AME dark, other eyes light; with black rings. Eye sizes and interdistances: AME 0.06, ALE 0.07, PME 0.06, PLE 0.06, AME–AME 0.05, AME–ALE 0.02, PME–PME 0.11, PME–PLE 0.04, MOQL 0.14, MOQA 0.18, MOQP 0.24. Legs yellowish, without distinct color markings. Leg formula: IV, I, II, III; leg measurements: I 2.91 (0.86, 0.45, 0.84, 0.51, 0.25), II 2.85 (0.92, 0.41, 0.71, 0.55, 0.25), III 2.06 (0.65, 0.33, 0.43, 0.44, 0.20), IV 3.60 (1.03, 0.36, 0.84, 1.04, 0.33). Opisthosoma ( Figs 12 E–F) elongate-oval, with some irregular color markings dorsally and laterally; dorsum with a pairs of muscular depressions; with conspicuous anterior hair tufts; venter and spinnerets light yellow. Palp ( Figs 11 A–E): tibia short, with two apophyses, VTA finger-like, elevated from a pit, base fused with base of RTA; RTA large and lamina-shaped, with a straight tip; genital bulb elongated, with a relatively flat tegulum, sperm duct distinctive, V-shaped; tegular hump indistinct; embolus inserted prolaterally (approximately nine o’clock relative of tegulum), aligned clockwise along the tegular distal margin, apex approximately at six o’clock position relative of tegulum. Female ( paratype IZCAS Ar 34590): Total length 3.08; prosoma 1.29 long, 0.83 wide; opisthosoma 1.86 long, 0.73 wide. Not strikingly different from males but darker in color ( Figs 12 G–H). Eye sizes and interdistances: AME 0.05, ALE 0.05, PME 0.06, PLE 0.03, AME–AME 0.06, AME–ALE 0.02, PME–PME 0.13, PME–PLE 0.04, MOQL 0.16, MOQA 0.14, MOQP 0.23. Legs yellowish, without distinct color markings. Leg formula: IV, II, I, III; leg measurements: I 2.57 (0.79, 0.42, 0.72, 0.43, 0.22), II 2.61 (0.82, 0.44, 0.80, 0.33, 0.22), III 2.06 (0.67, 0.33, 0.32, 0.51, 0.24), IV 3.17 (0.99, 0.37, 0.49, 0.97, 0.36). Epigyne ( Figs 12 A–D): Epigynal plate slightly longer than wide, posterior margin not rebordered; atrium large, located at posterior portion of epigynal plate; spermathecae, burse and copulatory ducts well visible through epigynal plate in ventral view; two copulatory openings large and conjoined; copulatory ducts thick, describing a π-shaped course in ventral view, ascending in parallel, bent vertically and directed ventrally to connect to spermathecae; ovoid spermathecae, situated anteriorly, connecting to posterior bursae; bursae globular, slightly larger than spermathecae; fertilization ducts short, located on dorsal-inner surface of spermathecae. Distribution . Presently known only from the type locality.
