Type material. Holotype, female (slide number NJAUAcariEriQ 94, marked Holotype), from Fissistigma retusum (Lévl.) Rehd.   ( Annonaceae   ), Bawangling Nature Reserve, Changjiang County, Hainan Province, P.R. China, 19 °07ʹ03ʹʹN, 109 °09ʹ02ʹʹE, elevation 650m, 30 September 2008, coll. Xiao-Feng Xue, Zi-Wei Song & Zhen Wang. Paratypes, 7 females and 1 male (slide number NJAUAcariEriQ 94), with the same data as holotype.

Relation to host. Vagrant on leaf surface. No damage to the host was observed.

Etymology. The specific designation retusus   is from the species name of host plant, retusum   .
