The russet mite, Aceria anthocoptes (Nalepa), is the only eriophyoid
that has been recorded on Cirsium arvense (L.) Scop. It has been noted
in several European countries and recently in the USA. In this study we
explored the geographic and host-related variability of Aceria spp.
inhabiting different Cirsium spp. We applied landmark-based geometric
morphometric methods to study morphological variability of three body
regions (ventral, coxigenital and prodorsal) of 13 Aceria spp.
populations inhabiting five Cirsium spp. in Serbia (Europe) and four
Cirsium spp. in Colorado (North America). Analyses of size and shape
variation revealed statistically significant differences between Aceria
spp. living on European native and North American native Cirsium spp.,
as well as between A. anthocoptes s.s. inhabiting European C. arvense
and North American C. arvense. The coxigenital region was the most
informative when considering inter-population shape differences.
European Aceria spp. dwelling on Cirsium spp., including A. anthocoptes
s.s. from C. arvense, are characterized by higher inter-population size
and shape variability than their North American counterparts. This
finding supports a Eurasian origin of A. anthocoptes, presumed to
consist of a complex of cryptic taxa probably coevolved with host plants
in the native environment. Morphological similarity among Aceria spp.
inhabiting North American native Cirsium spp. may indicate that
speciation of A. anthocoptes started relatively soon after the host
shift to plants different from C. arvense in the invaded region.
