Type material. Holotype female: CHINA: Guizhou Province: GoogleMaps Zunyi City, Suiyang County, Kuankuo Town   GoogleMaps , Dishui Village   GoogleMaps , Manwang Cave   GoogleMaps , 28.78°N, 107.90°E, 734 m, entrance to the cave, 21 April 2017, Y. Zhong leg. (CBEE). Paratype: 1 female, with same data as holotype ( CBEE) GoogleMaps .

Etymology. The specific name is derived from the Latin adjective columnaris , - is, - e, meaning “pillar-like” referring to the lobal septum being pillar-like.

Diagnosis. The females of this new species are similar to those of Sinopoda tengchongensis Fu & Zhu, 2008 ( Fu & Zhu 2008: figs 2–3) in having similarly slender lobal septum and small posterior parts of spermathecae, but can be separated by: 1. Lobal septum of epigyne without median groove in anterior part (with median groove along entire length in S. tengchongensis ); 2. Glandular appendages of vulva with tip slightly curved posteriad (straight and posterior-laterad in S. tengchongensis ); 3. Internal duct system of vulva touching along median line (not touching, only close in posterior part in S. tengchongensis ) ( Figs 16 View FIGURES 16 A–B, 17A–B).

Description. Female (holotype): Measurements: PL 8.4, PW 8.0; AW 4.4; OL 9.9, OW 6.0. Eyes: AME 0.41, ALE 0.56, PME 0.37, PLE 0.61, AME–AME 0.20, AME–ALE 0.11, PME–PME 0.43, PME–PLE 0.97, AME–PME 0.46, ALE–PLE 0.57, CH AME 0.15, CH ALE 0.20. Spination: Palp: 131, 101, 2121, 1014; Fe: I–III 323, IV 331; Pa: I–IV 101; Ti: I–IV 2326; Mt: I–II 1014, III 2026, IV 3036. Measurements of palp and legs: Palp 10.3 (3.6, 1.0, 2.2, –, 3.5); I 33.8 (9.6, 3.2, 9.6, 8.6, 2.8); II 35.2 (10.1, 2.9, 10.5, 9.0, 2.7); III 31.7 (9.5, 2.9, 8.9, 8.0, 2.4); IV 32.8 (9.8, 2.8, 9.0, 8.6, 2.6). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 26 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long, with short anterior bands and one slit sensillum on each side of the epigynal field. Lateral lobes fused, with groove in posterior part. Lobal septum anteriorly wider. Internal ducts running parallel along the median line, its anterior part slightly wider than posterior part. Fertilization ducts arising posterio-laterally.

Colouration in ethanol. Dorsal prosoma reddish-brown, lateral margins dark. Fovea and radial furrows distinctly marked. Labium and gnathocoxae deep brown, both with distal parts lighter. Sternum yellowish-brown, with margin deep brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma reddish-brown, covered by brown hairs, with three pairs of muscle sigilla. Ventral opisthosoma yellowish-brown ( Figs 17 View FIGURES 17 C–D).
