Porrhoclubiona songbai Wu & Xu 2026, sp. nov.

Porrhoclubiona songbai Wu & Xu sp. nov. 松柏栅ú巢ss urn:lsid:zoobank.org:act: DE36B5D9-0D2F-45B9-BEE1-C2C98DD85DDC Fig. 11 Diagnosis The female of the new species resembles P. pteronetoides (Deeleman-Reinhold, 2001) in having similarly large CO situated near the epigastric furrow, and translucent, wrinkled CD, and reniform SP (compare Fig. 11C–F with Zhang et al. 2021c: fig. 16a–d). However, it can be easily distinguished from P. pteronetoides by the CD being distinctly longer and extending anteriorly beyond the SP, with their distal ends looping around the base of the spermathecae (Fig. 11C–F) (vs CD not extending beyond the SP anteriorly and their twisted ends connecting directly to the SP in P. pteronetoides, as in Zhang et al. 2021c: fig. 16a–d). Etymology The specific epithet refers to the type locality; noun in apposition. Type material Holotype CHINA • ♀; Guangxi Zhuang Autonomous Region, Fangchenggang City, Shiwandashan National Nature Reserve, Songbai Station; 21°58′ N, 108°01′ E; 303 m a.s.l.; 1 May 2021; J. Liu leg; HNU1401. Description Female (holotype HNU1401) Total length 4.40; carapace 1.75 long, 1.25 wide; abdomen 2.53 long, 1.28 wide. Carapace oval, yellowish brown with anterior part light orange, densely covered with short, fine setae; fovea black, inconspicuous; cephalic region slightly narrowed; cervical groove distinct, radial groove indistinct (Fig. 11A). Eyes: AER distinctly recurved; PER slightly procurved and wider than AER in dorsal view. Eye sizes and interdistances: AME 0.08, ALE 0.07, PME 0.10, PLE 0.09; AME–AME 0.06, AME–ALE 0.05, PME–PME 0.20, PME–PLE 0.09; MOQL 0.24, MOQA 0.23, MOQP 0.36. Chelicerae yellow, with three promarginal and two retromarginal teeth. Sternum bright yellow, 0.95 long, 0.55 wide. Labium and endites yellowish white, longer than wide. Legs yellowish white, unmarked. Leg measurements: I 3.21 (0.90, 0.54, 0.80, 0.58, 0.39), II 3.52 (1.02, 0.60, 0.91, 0.62, 0.37), III 2.98 (0.91, 0.37, 0.67, 0.66, 0.37), IV 4.48 (1.17, 0.55, 1.26, 1.06, 0.44). Leg formula: 4213. Abdomen grayish brown, uniformly colored, densely covered with setae, lacking distinct dorsal markings, with two pairs of muscle depressions centrally located on dorsal side (Fig. 11A). Ventral side slightly paler than dorsal one, unmarked. Spinnerets short, yellow (Fig. 11B). EPIGYNE (Fig. 11C–F). Epigynal plate longer than wide, with SP and CD visible through integument in ventral view. CO large, oval, located posteriorly on epigynal plate near epigastric furrow. CD tubular, translucent, with wrinkled and ribbed appearance; ascend anteriorly in front of spermathecae, then curve inward, descend posteriorly in ventral view, and finally loop around base of spermathecae before connecting to both SP and BS. SP reniform. BS situated posteriorly, translucent, and globular. Male Unknown. Distribution Known only from the type locality in Guangxi Zhuang Autonomous Region, China. Remarks The new species also resembles Clubiona wulingensis Yu & Chen, 2017, which should likewise be transferred to the genus Porrhoclubiona (given the lack of available material and that this issue is beyond the scope of the present study, we retain its current taxonomic status). It can be distinguished from C. wulingensis by the dorsal part of the CD being ca ⅓ the diameter of the SP and positioned in the front of them in dorsal view (Fig. 11C–F) (vs dorsal part ca half the diameter of the SP and positioned behind them in C. wulingensis, as in Yu & Chen 2017: figs 7–9).
