Holotype female, Xincheng County (24 ° 0 ′ N, 108 ° 36 ′ E), Guangxi Zhuang Autonomous Region, China, 20 May 2011, from Panicum notatum Retz. (Poaceae), coll. Shan-Sheng Ou and Sui-Gai Wei. Paratypes 14 females and 1 male, mounted on individual slide, same data as holotype. Biology. The mites are free-living on the undersurface of leaves, no conspicuous damage was observed. Etymology. This species is named after the generic name of the type host plant. Remarks. This new species is similar to A. arunis Chen, Wei & Qin, 2004, but can be diagnosed by: opisthosoma dorsal aspect smooth, dorsal annuli at lateral parts with rounded microtubercles; ventral annuli with rounded microtubercles; tarsal empodium 8 - rayed. In A. arunis, the opisthosoma with a little fan-shaped design on the dorsal median ridge of 1 – 22 annuli, each dorsal annulus with 3 – 4 short lines on lateral ridges; tarsal empodium 7 - rayed (Chen, Wei & Qin, 2004).
