Types.

Holotype ♂: CHINA, Yunnan: Menglun Town: Xishuangbanna Botanical Garden, 5.-12.07.2007, fogging. Paratype 1♂, 21°54.555'N, 101°16.860'E, elevation ca 610 m, 29.11.2009, evergreen forest, fogging. Paratypes 1♀, 21°53.823'N, 101°17.072'E, elevation ca 613 m, 5.-12.03.2007, Paramichelia baillonii plantation, hand-collecting; 1♀, 21°54.459'N, 101°16.750'E, elevation ca 640 m, 20.XI.2009, G213 Road, secondary forest, fogging.

Etymology.

This name is from the Chinese Pinyin ‘bì shǒu’, meaning 'short/small sword’, which refers to the sword-shaped tibial dorsal apophysis; noun in apposition.

Diagnosis.

Male of new species is similar to Parameioneta biobata Tu & Li, 2006, but differs in the following aspects: Parameioneta biobata has one curved tibial apophysis ( Tu and Li 2006: fig. 7A), while Parameioneta bishou sp. n. has three (Figs 77 A–B, 78 A–B); paracymbium’s apex in Parameioneta bishou sp. n. is broad (Fig. 77B), not as slim as in Parameioneta biobata ( Tu and Li 2006: fig. 7A); lamella characteristica in Parameioneta bishou sp. n. has two branches, both of which are long and pointed (Fig. 78B), while in Parameioneta biobata one is pointed, the other is broad at tip ( Tu and Li 2006: fig. 7C). The female is distinguished from other congeners by the conformation of epigyne.
