Type material.

Holotype ♂, CHINA, Yunnan Province, Xishuangbanna Prefecture, Mengla County, Menglun Town, XTBG (Xishuangbanna Tropical Botanical Garden), Yunnan Rubber Plantation (575 m; 21°54.46'N, 101°15.98'E), 21 July 2007, Guo Zheng leg. Paratypes: 9 ♂, 10 ♀, same data as holotype.

Diagnosis.

Among the Chinese species of the corticalis -group, this new species resembles Clubiona moralis , but differs by: a wider and triangular embolus (filiform and coiled in Clubiona moralis ), presence of only one round, black marking on tegulum (several fan-shaped markings in Clubiona moralis ); fertilization ducts opening in the medio-ventral side of the spermathecae (anteriorly in Clubiona moralis ); and the spermathecae almost as large as the bursae (the bursae twice longer than the spermathecae in Clubiona moralis ) (Figs 3-12).

Etymology.

The species name refers to a close resemblance between the new species and Clubiona moralis .

Cymbium longer than tegulum. Tegulum inflated, with a round, black marking medially; embolus short, wide, almost triangular in ventral view; conductor membranous, folded in the middle position, and almost threefold longer than wide.
