Etymology.

The specific name is derived from the type locality; an adjective.

Diagnosis.

Among the species of the Clubiona corticalis group, the male (Fig. 2 View Figure 2 ) of this new species resembles C. multiprocessa sp. nov. (Fig. 5 View Figure 5 ) by having a long (more than 1 / 2 of femur length), finger-shaped RFA (vs RFA absent or, if present, not finger-shaped in all other species in the grouper; e. g. tongue-shaped in C. lamellaris as shown by Zhang et al. 2018: figs 3 C, 4 C). However, the new species can be distinguished by the following: (1) VTA triangular, apex sharp (Fig. 2 B, C View Figure 2 ) (vs papilliform; Fig. 5 A, C View Figure 5 ); (2) LTA shaped like an inverted trapezoid, distal tip truncated in retrolateral view (Fig. 2 C View Figure 2 ) (vs ridge-like; Fig. 5 C View Figure 5 ); (3) conductor extends at a 45 ° angle towards the base of the embolus (Fig. 2 A View Figure 2 ) (vs extends in a more or less 7 - shaped; Fig. 5 A View Figure 5 ); (4) embolus claw-shaped, with a curved apex in ventral view (Fig. 2 A View Figure 2 ) (vs shaped like an equicrural triangle, embolic tip not curved; Fig. 5 A View Figure 5 ). The female is similar to C. falciforma Liu, Peng & Yan, 2016 ( Liu et al. 2016: 567, figs 30, 31, 35, 36) in the general shape of vulva (Fig. 3 View Figure 3 ), but the new species can be distinguished by the following: (1) atrium umbelliform, with arched hood (vs elliptical and hood lacking); (2) bursae spherical (vs elongate-oval).

Male (holotype) (Fig. 1 A, B View Figure 1 ): total length 4.50. Carapace 2.14 long, 1.52 wide; abdomen 2.36 long, 1.24 wide. Carapace yellowish brown, narrowed in pars cephalica, widest between coxae II and III, clothed with short fine hairs along the ridge of the thoracic region, forming a V-shaped region. Fovea longitudinal. AER slightly recurved, PER wider than AER, almost straight in dorsal view. Eye sizes and interdistances: AME 0.06, ALE 0.10, PME 0.08, PLE 0.10; AME – AME 0.05, AME – ALE 0.03, PME – PME 0.17, PME – PLE 0.11. MOA 0.28 long, front width 0.21, back width 0.36. Chelicerae reddish brown, with seven promarginal and five retromarginal teeth, with dense scopula in both margins. Clypeus height 0.05. Sternum light orange, 1.14 long, 0.71 wide. Labium and endites coloured as chelicerae, anterior edge with dark scopula, longer than wide. Legs yellowish brown, without distinct colour markings. Leg measurements: I 4.17 (1.13, 0.62, 1.35, 0.62, 0.45), II 4.24 (1.19, 0.63, 1.45, 0.52, 0.45), III 3.58 (1.01, 0.59, 1.02, 0.57, 0.39), IV 4.32 (1.25, 0.59, 1.49, 0.53, 0.46). Abdomen elongate-oval, dorsum pale yellow, with conspicuous anterior tufts of hairs, and two pairs of inconspicuous muscular depressions; venter pale yellow, with numerous yellowish spots.

Palp (Fig. 2 View Figure 2 ). Femur retrolaterally with a slanting finger-like apophysis (RFA), more than 1 / 2 of femur’s length. RFA partly membranous, arising mesially from femur, directing retrolatero-dorsally. Patella approximately twice as long as the tibia, with two apophyses: PPA large, broad, and blunt, located medially, represented by an enlarged tubercle; RPA short, almost thumb-shaped in ventral view, more or less inverted V-shaped in retrolateral view, located distally. Tibia short, with three apophyses: RTA short, with beak-shaped tip in ventral view, broad, flat, nearly triangular in retrolateral view, apex sclerotized; VTA short and membranous, almost triangular in lateral view; LTA shaped like an inverted trapezoid, distal tip truncated in retrolateral view. Cymbium almost 1.8 × longer than wide. Tegulum elongated oval, ca 1.6 × longer than wide; subtegulum visible prolaterally. Sperm duct long and sinuated, running an irregular course in the prolateral part of the tegulum. Embolus (E) originating at distal portion of tegulum, claw-shaped, apex curved ventrally. Conductor (C) large, originating from retrolateral side of tegulum, about 2 o’clock position, widest in the mid part, terminal part heavily sclerotized, beak-shaped, apex directing prolaterally.

Female (paratype) (Fig. 1 C, D View Figure 1 ): one specimen body length 4.39. Carapace 2.10 long, 1.55 wide; abdomen 2.29 long, 1.53 wide. Carapace reddish brown, clothed with short fine hairs. Eye sizes and interdistances: AME 0.08, ALE 0.12, PME 0.09, PLE 0.10; AME – AME 0.06, AME – ALE 0.06, PME – PME 0.19, PME – PLE 0.15. MOA 0.30 long, front width 0.23, back width 0.39. Clypeus height 0.04. Sternum 1.24 long, 0.74 wide. Chelicerae, labium, and endites coloured as carapace. Leg measurements: I 3.76 (1.24, 0.41, 1.16, 0.56, 0.39), II 3.92 (1.20, 0.49, 1.12, 0.65, 0.46), III 3.47 (1.26, 0.47, 0.92, 0.56, 0.26), IV 4.15 (1.45, 0.58, 1.07, 0.68, 0.37). Abdomen oval, dorsum yellowish brown, with numerous, short fine hairs and two pairs of inconspicuous muscular depressions.

Epigyne (Fig. 3 View Figure 3 ). Epigynal plate slightly longer than wide. Atrium (A) distinctly large, umbelliform, with a delimited, arched anterior margin (hood) and nearly invisble postterior margin, located at anterior portion of epigynal plate. Copulatory openings (CO) indistinct, tiny, located centrally in atrium. Copulatory ducts (CD), heavily sclerotised, relatively long and thick, ca 1 / 2 length of epigynal plate, descend obliquely, forming a ˄ - shaped course. Spermathecae (S) longer laterally juxtaposed at the tip represented by two ~ - shaped tubes, anterior surface with a papilliform spermathecal appendage (SA), respectively. Fertilisation ducts (FD) acicular, located terminally on spermathecae. Bursae (B) close together, spherical, weakly sclerotized, surface smooth.
