Type material. Holotype male: CHINA: Sichuan Province GoogleMaps : Bazhong City, Nanjiang County, Guangwushan Scenic Area   GoogleMaps , 32.67°N, 106.80°E, 1003 m, native forest, 26 July 2014, L.Y. Wang & T. Lu leg. (CBEE). Paratypes: 2 males, 2 females, with same data as holotype ( CBEE) GoogleMaps .

Etymology. The specific name comes from the Latin word pyramidalis , meaning “pyramidal” referring to the pyramidal lobal septum.

Diagnosis. Males of this species resemble those of Sinopoda serpentembolus Zhang, Zhu, Jäger & Song, 2007 ( Zhang et al. 2007: figs 3–4) in having the embolus strongly S-shaped and a similarly shaped RTA in ventral view, but can be separated by: 1. Embolus tip almost straight (significantly curved in S. serpentembolus ); 2. Tegulum proximally rounded (with distinct projection in S. serpentembolus ); 3. dRTA larger and distinctly longer than vRTA (roughly the same size and only barely longer in S. serpentembolus ). Female can be distinguished from other Sinopoda species by epigyne with pyramidal lobal septum and conspicuously narrow lateral lobes ( Figs 50 View FIGURES 50 A–E, 51A–D, 52A–B).

Description. Male (holotype): Measurements: PL 5.9, PW 5.5; AW 2.7; OL 6.2, OW 3.4. Eyes: AME 0.22, ALE 0.33, PME 0.24, PLE 0.36, AME–AME 0.22, AME–ALE 0.08, PME–PME 0.32, PME–PLE 0.60, AME–PME 0.44, ALE–PLE 0.41, CH AME 0.23, CH ALE 0.27. Spination: Palp: 131, 101, 2121; Fe: I–III 323, IV 331; Pa: I–IV 101; Ti: I 3436, II–IV 2326; Mt: I–II 2014, III–IV 3136. Measurements of palp and legs: Palp 9.6 (3.3, 1.6, 1.7, –, 3.0); I 24.9 (6.7, 2.3, 6.8, 6.9, 2.2); II 28.4 (7.7, 2.3, 7.9, 8.0, 2.5); III 20.9 (5.4, 2.6, 5.7, 5.7, 1.5); IV 22.7 (5.9, 2.3, 6.2, 6.6, 1.7). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 22 denticles.

Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 8 to 9-o’clockposition in ventral view, with embolus tip as long as embolic apophysis. Embolic apophysis pointed in distal part, forming a triangle. RTA arising medially from tibia, vRTA well developed, extending beyond to half of dorsal RTA ( Figs 50 View FIGURES 50 A–C, 51A–D).

Colouration in ethanol. Dorsal prosoma yellowish- to slightly reddish-brown, lateral margins darker. Fovea and radial furrows distinctly marked. Labium and gnathocoxae yellowish-brown, both with distal parts brighter. Sternum yellowish-brown, with margin brown. Chelicerae deep reddish-brown. Legs yellowish- to slightly reddishbrown. Dorsal opisthosoma brown, with three pairs of dark patches laterally and one dark transversal band above spinnerets. Ventral opisthosoma brown with irregular pattern ( Figs 51 View FIGURES 51 E–F).

Female: Measurements: PL 5.4, PW 5.2; AW 3.2; OL 7.8, OW 4.9. Eyes:AME 0.20, ALE 0.35, PME 0.32, PLE 0.37, AME–AME 0.30, AME–ALE 0.14, PME–PME 0.36, PME–PLE 0.65, AME–PME 0.48, ALE–PLE 0.47, CH AME 0.26, CH ALE 0.31. Spination: Palp: 131, 101, 2121, 1014; Fe: I–III 323, IV 321; Pa: I–IV 101; Ti: I–II 2026, III 2226, IV 2326; Mt: I–II 1014, III–IV 3036. Measurements of palp and legs: Palp 6.9 (2.3, 0.9, 1.4, –, 2.3); I 16.8 (6.8, 2.1, 7.2, 6.1, 2.2); II 18.9 (5.9, 1.7, 5.2, 4.5, 1.6); III 15.9 (4.9, 1.5, 4.3, 3.7, 1.5); IV 18.1 (5.3, 1.6, 4.6, 4.8, 1.8). Leg formula: II-IV-I-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 33 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long, with short anterior bands. Lateral lobes fused, with small median incision. Internal ducts running parallel along the median line. Glandular appendages distinctly wider than posterior parts of spermathecae. Fertilization ducts arising posterioly ( Figs 50 View FIGURES 50 D–E, 52A–B).

Colouration in ethanol. As in males ( Figs 52 View FIGURES 52 C–D).
