L, lateral view of female; em, empodium; CGM, coxae and genitalia of male; LO, enlarged lateral view of opisthosoma. Type material. Holotype , female (slide No. NJAUAcariEri938, marked holotype ), from Jasminum humile L. ( Oleaceae ), Pai town, Nyingchi (Linzhi) Prefecture, Tibet Autonomous Region, P. R. China , 15 August , 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang. Paratypes , 5 females and 3 males (slides No. NJAUAcariEri938) with the same data as holotype . Relation to host. Vagrant on leaf undersurface. No damage to the host was observed. Etymology. The specific designation jasmini is from the host genus name “ Jasminum ”. Differential diagnosis. This species is similar to A. jingbois Xue, Song & Hong, 2008 , but can be differentiated by the prodorsal shield with all lines incomplete, with lateral granules (prodorsal shield with only admedian lines, with numerous granules on shield in A. jingbois ); female genital coverflap with 10 longitudinal ridges and smooth at base (female genital coverflap with 8 longitudinal ridges and with granules at base in A. jingbois ).
