Type material. Holotype ♂: CHINA: Hunan Province: Chenzhou City, Guidong County, Bamians Mountain National Nature Reserve , 26.001944°N, 113.710675°E, 1678 m, 16 Sept. 2019, Cheng Wang, Bo Lv and Xuan-Wei Zhou leg. (HNU-BMS-1903) GoogleMaps . Paratypes: 2♂ 2♀, same data as holotype (HNU-BMS-1903) GoogleMaps .

Etymology. The specific epithet is derived from the Latin “ latus ” (wide), referring to the wide conductor, adjective.

Diagnosis. The male of this new species is similar to that of Draconarius singulatus ( Wang, Yin, Peng & Xie, 1990) in the long patellar apophysis, wide retrolateral tibial apophysis and the short cymbial furrow, but can be distinguished by the following characters: 1) retrolateral tibial apophysis length almost equal to width in D. latus sp. nov. ( Fig. 5C View FIGURE 5 ), while longer than wide in D. singulatus ( Wang et al. 1990: fig. 38); 2) prolateral tibial apophysis present in D. latus sp. nov. ( Fig. 5A View FIGURE 5 ), while absent in D. singulatus ( Wang et al. 1990: fig. 36); 3) the distal portion of the conductor wider than tegulum sclerite and without gap in ventral view in D. latus sp. nov. ( Fig. 5B View FIGURE 5 ), while narrower than tegulum sclerite and with a gap in D. singulatus ( Wang et al. 1990: fig. 37); 4) conductor dorsal margin rostriform in ventral view in D. latus sp. nov. ( Fig. 5B View FIGURE 5 ), while cambered in D. singulatus ( Wang et al. 1990: fig. 37); 5) conductor dorsal apophysis long, with blunt distal end in D. latus sp. nov. ( Fig. 5B View FIGURE 5 ), while short, with pointed distal end in D. singulatus ( Wang et al. 1990: fig. 37). Female can be distinguished from any other congeneric species by spermathecal head transverse digitiform located anteriorly and extended laterally ( Fig. 5E View FIGURE 5 ).

Description. Male (holotype) ( Fig. 4A, B View FIGURE 4 ). Total length 8.29; carapace 4.21 long, 2.94 wide; clypeus 0.17 high. Abdomen 3.79 long, 2.06 wide. Carapace yellow brown, covered with black setae. Fovea longitudinal, radial and cervical grooves distinct. Eye sizes and interdistances: AME 0.13, ALE 0.17, PME 0.16, PLE 0.16; AME– AME 0.11, AME–ALE 0.09, PME–PME 0.13, PME–PLE 0.21. Chelicerae brown, with 3 promarginal teeth and 2 retromarginal teeth. Endites and labium yellow brown, distal end pale yellow and with dark setae. Sternum yellow brown. Leg pale yellow to brown. Measurements of legs: I, 11.74 (3.05, 3.88, 2.87, 1.94); II, 10.82 (2.95, 3.50, 2.64, 1.73); III, 10.28 (2.93, 3.12, 2.77, 1.46); IV, 13.30 (3.51, 4.08, 3.87, 1.84). Leg formula: 4123. Abdomen oval, dorsum anterior portion with sparse black setae, the posterior median area with 4 herring-bones; venter light yellow, with black maculation and setae.

Palp ( Fig. 5A–C View FIGURE 5 ). Patellar apophysis as long as the patella. Prolateral tibial apophysis digital, retrolateral tibial apophysis trapezoid and lateral tibial apophysis short. Cymbial furrow about 1/4 length of cymbium. Conductor: distal portion wide wavy shaped, basal lamella triangular dorsal margin rostriform and dorsal apophysis rodlike. Embolus long and thin, originated at about 6:00 o’clock position.

Carapace yellow brown, posterior portion covered with white setae. Fovea longitudinal, radial and cervical grooves distinct. Eye sizes and interdistances: AME 0.13, ALE 0.19, PME 0.16, PLE 0.16, AME–AME 0.08, AME–ALE 0.13, PME–PME 0.16, PME–PLE.0.22. Chelicerae with 3 promarginal teeth and 2 retromarginal teeth. Measurements of legs: I, 11.21 (3.25, 3.89, 2.52, 1.55); II, 9.79 (2.70, 3.23, 2.31, 1.55); III, 9.57 (2.95, 2.83, 2.37, 1.42); IV, 12.65 (3.49, 3.97, 3.34, 1.85). Leg formula: 4123. Abdomen brown, covered with setae, posterior median area of dorsum with 5 herring-bones.

Epigyne ( Fig. 5D, E View FIGURE 5 ). With 2 triangular long teeth on the medial sides of epigyne. Hoods shallow. Atrium semicircular, located in posterior portion of epigyne. Spermathecal base wrinkled, spermathecal stalk bean-shaped, spermathecal heads digital, located in the anterior portion. Fertilization duct digitiform and pointed to outside.

Distribution. Known only from the type locality ( Fig. 6 View FIGURE 6 ).
