Distribution. China (Sichuan, Taiwan, Fig. 24).

Remarks. This species was first recorded in Mt. Alishan, Taiwan (Vilkamaa & Hippa 1996) . It was also described as Phytosciara (Prosciara) flexa Rudzinski, 1996, which was regarded as a junior synonym of P. f u r t i v a by Menzel and Heller (2006). Vilkamaa & Hippa (1996) described the species based on a single type. The description provided was not comprehensive because many parts of the holotype were distorted or missing. Here we describe the species based on new materials from Sichuan province.
