Type material. Holotype ♂ (SWUC-T-AG-120-01), CHINA, Yunnan Province, Lincang City, Gengma County, Nangunhe National Nature Reserve , Nantianmen , 23°38'35"N, 99°23'6"E, elev. 1955 m, 28.11.2024, Z.Z. Yang et al. leg . Paratype: 1♀ (SWUC-T-AG-120-02), same data as holotype .

Etymology. The specific name is derived from the type locality; noun in apposition.

Diagnosis. Male of Draconarius nantianmen Kong, Yang & Zhang , sp. nov. resembles D. agrestis Wang, 2003 in having a tiny patellar apophysis, an elongated cymbial furrow, and proximally originated, long embolus ( Figs 4D–E ; Wang 2003, figs 10A–B), but can be distinguished by conductor with almost circular and developed membranous lamellar prolaterally ( Fig. 4D ) vs. semicircular pro-ventrally in D. agrestis ( Wang 2003: fig. 10A); conductor with medial constriction and bilobed termination ( Fig. 4E ) vs. uniform width and truncated termination in D. agrestis ( Wang 2003, fig. 10A); median apophysis closely appressed to bulb ( Figs 4D–E ) vs. separated from bulb except for connecting portion in D. agrestis ( Wang 2003: fig. 10A). Female resembles D. paratrifasciatus Wang & Jäger, 2007 in having the looped copulatory ducts and a shallow atrium ( Fig. 4G ; Wang & Jäger 2007: figs 66–72), but can be distinguished by atrium oval ( Fig. 4F ) vs. rounded in D. paratrifasciatus (Wang & Jäger 2007: fig. 66); copulatory ducts having four loops each ( Fig. 4G ) vs. at least seven loops in D. paratrifasciatus (Wang & Jäger 2007: fig. 67).

Description. Male holotype ( Fig. 4A ) total length 11.97. Prosoma 6.51 long, 4.68 wide; opisthosoma 5.37 long, 3.71 wide. Eye sizes and interdistances: AME 0.25, ALE 0.29, PME 0.32, PLE 0.32; AME–AME 0.10, AME–ALE 0.13, PME–PME 0.09, PME–PLE 0.31, ALE–PLE 0.08. MOA 0.71 long, anterior width 0.56, posterior width 0.73. Clypeus height 0.15. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 18.16 (5.03, 6.37, 4.47, 2.29); II 15.22 (3.99, 5.18, 3.79, 2.26); III 12.23 (3.43, 3.99, 2.89, 1.92); IV 15.50 (4.48, 5.66, 4.32, 1.04). Leg formula: 1423.

Palp ( Figs 4C–E ). Patella as long as tibia; patellar apophysis finger-like, measuring one-third length of patella. Retrolateral tibial apophysis wide, occupying about three-fourths of tibial length; lateral tibial apophysis small, almost triangular, widely separated from retrolateral tibial apophysis. Cymbial furrow about two-thirds of cymbial length. Conductor medially constricted and terminating in bilobed structure in ventral view, with near circular and developed membranous lamellar prolaterally; conductor dorsal apophysis present. Median apophysis closely appressed to bulb in retrolateral view. Embolus banded, arising at approximately 6 o’clock position.

Female paratype (SWUC-T-AG-120-02, Fig. 4B ) total length 12.34. Prosoma 6.59 long, 4.57 wide; opisthosoma 5.76 long, 4.17 wide. Eye sizes and interdistances: AME 0.20, ALE 0.28, PME 0.32, PLE 0.30; AME–AME 0.14, AME–ALE 0.21, PME–PME 0.11, PME–PLE 0.37, ALE–PLE 0.08. MOA 0.73 long, front width 0.60, back width 0.74. Clypeus height 0.27. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 15.34 (4.56, 5.46, 3.28, 2.04); II 13.07 (3.80, 4.59, 2.54, 1.30); III 10.35 (3.02, 3.49, 2.54, 1.30); IV 14.94 (4.32, 5.41, 3.73, 1.48). Leg formula: 1423.

Epigyne ( Figs 4F–G ). Epigynal plate wider than long, sclerotized, outline trapezoidal. Epigynal teeth small, located close to anterolateral margin of atrium, widely separated by 1.5 times atrial width. Atrium oval and shallow. Copulatory opening located anterolateral margin of atrium. Copulatory ducts with four loops each around spermathecae. Spermathecae gourd-shaped, with rounded spermathecal heads.

Distribution. Known only from the type locality, Yunnan, China ( Fig. 7 ).
