Type material. Holotype female: CHINA: Yunnan Province: Lincang City, Wulaoshan Forest Park, 23.91°N, 100.17°E, 2362 m, native forest, 11 November 2015, Y. Zhong & Y. Zhu leg. (CBEE). Paratypes: 2 females ( CBEE) , 1 female ( SMF), with same data as holotype .

Etymology. The specific name is derived from the Latin adjective latus, - a, - um, meaning “wide” referring to the wide posterior part of the lobal septum.

Diagnosis. Females of this new species can be distinguished from all other Sinopoda spp. by the small glandular appendages located in the posterior part of vulva ( Figs 29 A–B, 30A–B).

Description. Female (holotype): Measurements: PL 6.3, PW 5.8; AW 3.4; OL 7.0, OW 4.5. Eyes: AME 0.31, ALE 0.45, PME 0.34, PLE 0.45, AME–AME 0.30, AME–ALE 0.12, PME–PME 0.42, PME–PLE 0.77, AME–PME 0.43, ALE–PLE 0.53, CH AME 0.20, CH ALE 0.29. Spination: Palp: 131, 101, 2121, 1014; Fe: I–III 323, IV 332; Pa: I–IV 001; Ti: I–IV 2026; Mt: I–II 1014, III–IV 3036. Measurements of palp and legs: Palp 7.0 (1.6, 0.8, 1.7, –, 2.9); I 19.9 (5.6, 2.1, 5.6, 4.8, 1.8); II 21.7 (6.1, 2.1, 6.3, 5.4, 1.8); III 17.9 (5.4, 1.5, 5.1, 4.3, 1.6); IV 19.0 (5.4, 1.5, 4.9, 5.2, 2.0). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 21 denticles.

Copulatory organ as in diagnosis. Epigynal field wider than long. Lobal septum distinctly wide, anteriorly about 1/3, posteriorly more than 1/2 of epigynal width. Internal ducts running along the median line. Glandular appendages as wide as posterior parts of spermathecae. Fertilization ducts arising posterio-laterally ( Figs 29 A–B, 30A–B).

Colouration in ethanol. Dorsal prosoma yellowish-brown, almost entirely covered by reddish-brown setae, lateral margins dark, with two pairs of light patches and yellow submarginal transversal light band posteriorly. Fovea and radial furrows indistinct. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown, with submarginal darker oval. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma reddish-brown, covered by grey setae. Ventral opisthosoma yellow-brown, covered by grey setae ( Figs 30 C–D).

Distribution. China (Yunnan) ( Fig. 62 ).
