(L.) Des Moul. (Compositae), coll. Xue, Xiao- Feng.
Paratypes
,
7 females
, with the same data as
holotype
.
Relation to host.
Vagrant on leaf surface. No damage to the host was observed.
Etymology.
The specific designation
dendranthemae
is from the generic name of the host plant,
Dendranthema
.
Remarks.
This species is similar to
Epitrimerus amygdali
Xue & Hong, 2005
, but can be differentiated by the absence of admedian lines (admedian lines present in
E. amygdali
), paraxial tibial setae (
l'
) located at center (paraxial tibial setae (
l'
) located 1/3 at dorsal base in
E. amygdali
).
