Paratypes
,
7 females
(slide number NJAUAcariEri421), with the same data as

.
Relation to host.
Vagrant on leaf surface. No damage to the host was observed.
Etymology.
The specific designation
cathayensis
is from the species name of the host plant,
cathayensis
.
Differential diagnosis.
This species is similar to
Proartacris taiwanensis
Huang, 2001
, but can be differentiated from the latter by the prodorsal shield with median line present, admedian and submedian lines connected (median line absent, admedian and submedian lines separated in
Proartacris taiwanensis
), dorsal and ventral annuli with spiny microtubercles projecting ahead of rear annular margins (dorsal and ventral annuli on rear annular margins in
Proartacris
.
taiwanensis
), and coxal plates with short lines (coxal plates with granules in
Proartacris taiwanensis
).
