Types.

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.

Etymology.

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.

Diagnosis.

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 .
