Type material
Holotype female (slide number NJAUAcariEriHN128A.1; marked Holotype), from Phoebe hunanensis Hand.–Mazz. (Lauraceae), Zhangjiajie National Forest Park, Zhangjiajie City, Hunan Province, P.R. China, 29°20'41"N, 110°27'33"E, elevation 420m, 10 July 2013, coll. Qiong Wang, Xiao Han and Jingfeng Guo, deposited as a slide mounted specimen in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China. Paratypes 4 females and 1 male on 5 microscope slides (slide number NJAUAcariEriHN128A.2-128A.6), with the same data as holotype.
Relation to host
Vagrant on lower part of the leaf surface. No damage to the host plant was observed.
Etymology
The specific designation setalsolenidion is derived from the shape (setal) of the tarsal solenidion. It is regarded as a noun phrase regardless of the gender and part of speech.
Differential diagnosis
This new species is similar to Phyllocoptes machilus Wei, Xie & Chen, 2006, but can be differentiated from the latter mainly by possessing: prodorsal shield lacking median, admedian and submedian lines (with median line incomplete, present on the anterior and rear 1/5 respectively, admedian lines complete, forming a network in Phyllocoptes machilus); anterior shield lobe acuminate, ending in a sharp point (with small frontal lobe in Phyllocoptes machilus); femur having fine granules (femur smooth in Phyllocoptes machilus) and tarsal empodium 8-rayed, tarsal solenidion seta-like (tarsal empodium 4-rayed, tarsal solenidion knobbed).
