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
).
