Type material. Holotype ♂ (SWUC-T-AG-118-01): CHINA, Yunnan Province, Lincang City, Gengma County, Nangunhe National Nature Reserve , Nantianmen , 23°38′44″N, 99°23′28″E, elev. 2007 m, 2024.9.23, Y.J. Cai and L.X. Cheng leg. Paratypes: 1♂ 1♀ (SWUC-T-AG-118-02~03), same data as holotype ; 1♂ (SWUC-T-AG-118-04), Lincang City , Gengma County, Nangunhe National Nature Reserve , Xinshanyakou, 23°38′32″N, 99°23′0″E, elev. 1963 m, 2024.9.24, Y.J. Cai and L.X. Cheng leg.

Etymology. The specific name refers to the adjective, referring to the anterior part of spermathecae compressed spring-like.

Diagnosis. Male of Draconarius meniscatus Kong, Yang & Zhang , sp. nov. resembles D. dorsiprocessus Zhang, Zhu & Wang, 2017 in having the similar retrolateral tibial apophysis and embolus ( Figs 2C–E ; Zhu et al., 2017: 267, figs 147A–C), but can be distinguished by conductor sclerotized with end extending retrolaterally ( Fig. 2D ) vs. dorsal side of conductor membranous with end extending posteriorly in D. dorsiprocessus ( Zhu et al., 2017: fig. 147A–B); cymbial furrow almost 1/4 length of cymbium ( Fig. 2E ) vs. about 1/3 length of cymbium in D. dorsiprocessus (fig. 147C); retrolateral tibial apophysis occupying third-forths of tibial length ( Figs 2D–E ) vs. two-thirds in D. dorsiprocessus ( Zhu et al., 2017: fig. 147A); patellar apophysis near semicircular with hook-like process and slightly overlapping with retrolateral tibial apophysis ( Figs 2D–E ) vs. finger-like, completely separated from retrolateral tibial apophysis in D. dorsiprocessus ( Zhu et al., 2017: fig. 147C). Female can be distinguished from other congeners by spermathecae 1.5 times longer than wide and tightly coiled with distinct six loops each ( Fig. 2G ).

Description. Male holotype ( Fig. 2A ) total length 12.57. Prosoma 6.89 long, 4.46 wide; opisthosoma 5.83 long, 3.75 wide. Eye sizes and interdistances: AME 0.24, ALE 0.31, PME 0.27, PLE 0.28; AME–AME 0.10, AME–ALE 0.10, PME–PME 0.14, PME–PLE 0.27, ALE–PLE 0.07. MOA 0.68 long, anterior width 0.51, posterior width 0.65. Clypeus height 0.18. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 16.07 (4.33, 5.51, 3.78, 2.45); II 14.50 (4.00, 4.71, 3.45, 2.34); III 13.03 (3.63, 3.76, 3.47, 2.17); IV 18.02 (4.79, 5.56, 5.07, 2.60). Leg formula: 1423.

Palp ( Figs 2C–E ). Patella about half of tibial length, patellar apophysis near semicircular with hook-like process and slightly overlaps with retrolateral tibial apophysis. Retrolateral tibial apophysis occupies about three-fourths of tibial length; lateral tibial apophysis almost triangular, close to dorsal side of cymbium. Cymbial furrow about one-thirds of cymbial length. Conductor broad and sclerotized with end extending retrolaterally in ventral view; conductor dorsal apophysis present. Median apophysis membranous. Embolus arises at approximately 6 o’clock position.

Female paratype (SWUC-T-AG-118-02, Fig. 2B ) total length 10.60. Prosoma 4.56 long, 3.06 wide; opisthosoma 5.60 long, 3.57 wide. Eye sizes and interdistances: AME 0.13, ALE 0.23, PME 0.20, PLE 0.20; AME–AME 0.11, AME–ALE 0.07, PME–PME 0.11, PME–PLE 0.15, ALE–PLE 0.09. MOA 0.52 long, front width 0.38, back width 0.55. Clypeus height 0.21. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 11.27 (3.11, 4.03, 2.42, 1.71); II 10.03 (3.02, 3.13, 2.25, 1.63); III 9.48 (2.73, 2.94, 2.39, 1.42); IV 12.29 (3.14, 4.10, 3.33, 1.72). Leg formula: 1423.

Epigyne ( Figs 2F–G ). Epigyne without teeth. Epigynal plate wider than long, sclerotized, outline trapezoidal. Copulatory opening located in triangular atrium posterolaterally. Spermathecae 1.5 times longer than wide and tightly coiled with distinct six loops each, without distinct spermathecal heads.

Variation. Males ( n = 3) total length 11.49–12.57.

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