Holotype ♀: CHINA, Yunnan: Menghai County: Manguan Village: Xishuangbanna nature reserve, 22°01.772'N, 100°23.711'E, elevation ca 1187 m, 1.07.2013, secondary forest, hand-collecting.


This name comes from the Latin word ‘bracteatus’, which means 'covered by scale, small fig’, in reference to the scale-shaped structure on the ventral fig; adjective.


It is similar to Gongylidiellum latebricola  (O. P.-Cambridge, 1871) by the shape of epigyne and the conformation of vulva ( Roberts 1987: 80, fig. 34c; Tanasevitch 1990: 111, fig. 24.40); its ventral fig is equipped with a pair of small membraneous extensions (Fig. 42A), which couldn’t be seen in Gongylidiellum latebricola  .


Female (holotype). Total length: 1.48. Carapace 0.70 long, 0.56 wide, light yellow. Sternum 0.31 long, 0.39 wide. Clypeus 0.13 high. Chelicerae promargin with 3 teeth, retromargin with 2 teeth. Eye sizes and interdistances: AME 0.04, ALE 0.06, PME 0.05, PLE 0.06, AME-AME/AME 0.75, PME-PME/PME 1.00, AME-ALE/ALE 0.17, PME-PLE/PLE 0.33, coxae IV separated by 1.64 times their width. Length of legs: I 2.13 (0.61, 0.20, 0.53, 0.48, 0.31), II 2.26 (0.64, 0.19, 0.56, 0.53, 0.34), III 1.65 (0.45, 0.17, 0.36, 0.41, 0.26), IV 2.16 (0.64, 0.17, 0.50, 0.54, 0.31). Leg formula: II-IV-I-III. TmI 0.65, TmIV 0.63. Tibial spine formula: 1-1-1-1. Abdomen pale, with a black posterior tip. Epigyne: ventral fig half rounded (Figs 42A, 43A); dorsal fig with a curved posterior margin; copulatory ducts make two turnings before joining the spermathecae (Fig. 42C); spermathecae rounded, separated by 1.5 their diameter (Fig. 42C); fertilization ducts long, following a ‘C’ -shaped route (Fig. 43B).
