Holotype ♂, China, Yunnan, Xishuangbanna, Menglun , Paramichelia baillonii plantation (about 20 years) (21º54.772'N, 101º16.043'E), 1–15 April 2007, Guo Zheng leg.

Paratype 1♀, Menglun, Paramichelia baillonii plantation (about 20 years) (21º53.823'N, 101º17.072'E), 16–30 April 2007, Guo Zheng leg.

Etymology. The specific name derives from the Latin adjective strumifer and means bossed, in reference to the prosoma and opisthosoma with many outgrowths.
