,
14 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
actinidiae
is from the generic name of the host plant,
Actinidia
.
Remarks.
This species is similar to
Tetra lucidi
Xue, Song & Hong, 2006
, but can be differentiated by coxal area with granules (coxal area smooth in
T
.
lucidi
), dorsal annuli with short-line microtubercles (dorsal annuli smooth in
T
.
lucidi
); submedian lines separated on prodorsal shield (submedian lines connected at base on prodorsal shield in
T
.
lucidi
).
