Type material. Holotype: ♁ (MHBU-ARA-00025219), CHINA: Yunnan Province, Lincang City, Shuangjiang County, Mengmeng Town (ÞÞDZ), 23.424582°N, 99.864808°E, 1969 m a.s.l., 15 June 2022, leg. L. Zhang, W. Wang, M. Xu & Z. Yang. GoogleMaps Paratypes: 2♁ 2♀ (MHBU-ARA-00025220), same data as holotype GoogleMaps .

Etymology. The species is named after a kind of Chinese halberd, the buziji, referring to the shape of the whole embolus in ventral view. Noun in apposition.

Diagnosis. The males resemble Euochin lingyi sp. nov. and E. subwanyan (Wang & Li, 2020) in the genital morphology, but can be distinguished by the sharpened tip of embolic flange ( Fig. 27 View FIGURES 24–30 ; vs. tip obtuse in E. lingyi sp. nov. and E. subwanyan , cf. Figs 80, 82 View FIGURES 80–84 , 113). The females share similarities with E. lingyi sp. nov., E. nanjiabawa sp. nov., E. tianhe sp. nov. in their epigyne structures, but can be distinguished by the laterally located copulatory openings that are far from each other, and the longer copulatory duct ( Figs 29–30 View FIGURES 24–30 , 33–34 View FIGURES 31–34 ; vs. centrally located copulatory openings that are close to each other, and the shorter copulatory duct in E. lingyi sp. nov., E. nanjiabawa sp. nov., E. tianhe sp. nov., cf. Figs 83–84 View FIGURES 80–84 , 87–88 View FIGURES 85–88 , 115–116, 119–120, 164–165, 168–169).

Description. Male. Habitus see Figs 19, 21 View FIGURES 19–23 . Carapace length 1.665; abdomen length 1.423. Eye measurements: AME 0.360, ALE 0.233, PME 0.081, PLE 0.208. Leg measurements: I 2.541 (0.846, 0.338, 0.617, 0.404, 0.336), II 2.438 (0.884, 0.355, 0.531, 0.353, 0.315), III 2.801 (0.975, 0.338, 0.573, 0.566, 0.349), IV 2.914 (0.929, 0.346, 0.591, 0.647, 0.401); leg formula: 4312. Color in ethanol: carapace dark brown, with white setae. Abdomen dark brown, with yellowish-white bands and spots. Chelicera ( Fig. 23 View FIGURES 19–23 ) with two promarginal and one retromarginal teeth. Palp ( Figs 24–28 View FIGURES 24–30 , 31–32 View FIGURES 31–34 ): distal femur and patella covered with long white setae; plane of embolic disc nearly horizontal, with blade-like flange; embolus nearly perpendicular to plane of embolic disc; tegulum with marked posterior lobe; cymbial flange obvious; tip of RTA sharpened, dagger-like in retrolateral view.

Female. Habitus see Figs 20, 22 View FIGURES 19–23 . Carapace length 1.715; abdomen length 2.220. Eye measurements: AME 0.353, ALE 0.240, PME 0.075, PLE 0.214. Leg measurements: I 2.493 (0.830, 0.397, 0.564, 0.359, 0.343), II 2.177 (0.818, 0.275, 0.461, 0.324, 0.299), III 2.732 (0.964, 0.339, 0.552, 0.476, 0.401), IV 3.178 (1.008, 0.426, 0.681, 0.674, 0.389); leg formula: 4312. Color in ethanol: similar to that of male, but lighter in coloration. Chelicera as in male. Epigyne ( Figs 29–30 View FIGURES 24–30 , 33–34 View FIGURES 31–34 ): epigynal window obtuse trapezoidal, with weakly sclerotized median septum; copulatory opening located posterior-laterally on margin of epigynal window; copulatory duct connected antero-centrally with spermatheca; spermatheca circular, bottom close to genital furrow.
