Relation to host.
Vagrant on leaf surface. No damage to the host was observed.
Etymology.
The specific designation
changqingiensa
is from the location name, where the new species were collected.
Differential diagnosis.
This species is similar to
Acaphyllisa adamantis
Song, Xue & Hong, 2008
, but can be differentiated from the latter by setae
h1
present (setae
h1
absent in
Acaphyllisa adamantis
), dorsal annuli with microtubercles (dorsal annuli smooth in
Acaphyllisa adamantis
), and admedian and submedian lines connected (admedian and submedian lines separated in
Acaphyllisa adamantis
).
Note.
The new species co-occurred with
Aculops salixis
Xue, Song & Hong 2007
.
