Types.

Holotype ♀: CHINA, Yunnan: Menglun Town: Xishuangbanna Tropical Botanical Garden, 21°54.380'N, 101°16.518'E, elevation ca 627 m, 22.11.2009, bamboo plantation, fogging.

Etymology.

This name comes from the Chinese Pinyin ‘biān tū’, meaning 'knobs on each side’, referring to the prominence on each side of the ventral fig of epigyne; noun in apposition.

Diagnosis.

This species is diagnosed by short copulatory ducts (Fig. 67A), position of spermathecae (Fig. 67C); it differs from congeners by tibial spination (1-1-1-1 in new species and 2-2-1-1 in other), the knob on each side of ventral fig and the long slits on the ventral fig (Fig. 67A).

Length of legs: I 1.57 (0.44, 0.19, 0.38, 0.31, 0.25), II 1.50 (0.43, 0.19, 0.35, 0.28, 0.25), III 1.32 (0.34, 0.16, 0.34, 0.25, 0.23), IV 1.63 (0.47, 0.16, 0.41, 0.34, 0.25).

Epigyne: ventral fig broad and slightly swollen, with a wavy posterior rim and one small knob on each side (Figs 67A, 68A); copulatory ducts complex (Figs 67C, 68B); spermathecae oval, separated by 2.00 times their diameter; fertilization ducts short (Fig. 67B).
