sp. nov.
A, dorsal view of female; B, coxae and female genitalia; C, legs I and II; D, lateral aspect of female; E, tarsal empodium.
Relation to host
Mites are vagrant on the undersurface of leaves, causing no apparent damage.
Etymology
The specific designation
euonymusae
is from the generic name of the
type
host plant,
Euonymus
.
Note
This species is similar to
Phyllocoptes acanthopanacis
Kuang, 1991
, but can be differentiated by the longer frontal lobe (shorter and broader in
acanthopanacis
), more distinctive prodosal shield pattern in
acanthopanacis
, dorsal annuli with elliptical microtubercles on rear annular margins (with minute round microtubercles in
acanthopanacis
), female genital coverflap with 12 longitudinal ridges and basal granules (with 8–10 longitudinal ridges and smooth base in
acanthopanacis
).
