Diagnosis. The appearance of this species is similar to Nandicius kuankuoshuiensis Wang, Mi, Irfan & Peng, 2019 , but can be easily differentiated by the wider embolus, the narrower posterior lobe of the tegulum (PL), the hooked RTA, the presence of a middle septum, and the laterally pointed pockets of the epigynum ( Figs 155–161, 163–165 View FIGURES 154–160 View FIGURES 161–165 ; vs. embolus thin, PL wide, RTA finger-shaped, the epigynum lacking a septum and with two pockets pointing to the middle in N. kuankuoshuiensis , see Wang et al. 2019: 117, figs 1B–D, 2A–B).

Description. Male. Habitus as in Figs 139, 140, 143–145 View FIGURES 139–143 View FIGURES 144–153 . Measurements: carapace 1.47 long, 1.14 wide, abdomen 1.94 long, 1.02 wide; eye measurements: AME 0.31, ALE 0.17, PME 0.05, PLE 0.15; leg measurements: Ⅰ 2.83 (0.83, 0.47, 0.69, 0.43, 0.41), II 2.15 (0.68, 0.30, 0.48, 0.32, 0.37), III 2.29 (0.68, 0.30, 0.47, 0.39, 0.45), IV 2.73 (0.84, 0.34, 0.62, 0.54, 0.39); leg formula 1432. Carapace black except middle and edge orange, covered with sparse yellow scales ( Figs 144, 145 View FIGURES 144–153 ). Chelicerae brown, with two promarginal and one retromarginal teeth. Abdomen with fishbone-like marking, middle and edge covered with white scales ( Figs 144, 145 View FIGURES 144–153 ). Legs orange, leg I darker than others ( Figs 139, 140, 143 View FIGURES 139–143 ).

Palp (154–156, 161–163): embolus wide and dagger-like in ventral view; RTA thin and hook-shaped; cymbial apophysis round, between RTA and dorsal tegular apophysis (DTA).

Female ( Figs 141, 142 View FIGURES 139–143 , 146, 147 View FIGURES 144–153 ): See Hu (2001: 387) for description.

Natural history. Foliage dwellers ( Fig. 9 View FIGURES 8–13 ).

Distribution. China (Xizang) ( Fig. 1 View FIGURE 1 ).

Remarks. The female allotype specimen of Pancorius armatus Jastrzębski, 2011 (later transferred to Yaginumaella by Wang et al. 2024) was misidentified; it is not paired with the male holotype of Pancorius armatus , but should be the female of Nandicius gyirongensis ( Hu, 2001) comb. nov. based on morphological features (also see comment in Wang et al. 2024).
