Material examined. Holotype, female, from Lonicera sp. ( Caprifoliaceae ), Wanglang Nature Reserve (33º00′01′′N, 104º02′02′′E; elev. 2836 m), Pingwu County, Sichuan, China, 15 August 2016, coll. Manchao Xie. GoogleMaps Paratypes. 6 females and 1 male, the same data as holotype GoogleMaps .

Relation to host. The mites are vagrants on the undersurfaces of the leaves, no obvious damage seen.

Etymology. The specific name is from the Latin lonicer and is, lonicer is derived from the generic name of the host plant, and is does for masculine gender end.

Remarks. This new species is firstly reported on Lonicera spp. for the genus Aculops . The species is similar to A. ulmi Hong & Xue, 2005 and A. ailanthi Lin, Jin & Kuang, 1997 in the shield design pattern and the smooth coverflap of female genitalia. But it can be differentiated from them by the opisthosoma with dorsal annuli smooth, and the tarsal empodium 6- rayed (the dorsal annuli sculptured with microtuberculate spiny and the tarsal empodium 2-rayed in A. ulmi ; the dorsal annuli sculptured with microtuberculates and the tarsal empodium 5-rayed in A. ailanthi ). Moreover, the new species can also be differentiated from A. ailanthi by the prodorsal shield design without nets (shield design with close nets in A. ailanthi ).

Additionally, the new species looks like the member of Rhyncaphytoptus by having a fairly strong gnathosoma projecting somewhat straight down, except the small, sharp anterior shield lobe over gnathosoma base and scapular setae (sc) projecting to rear.
