Relation to host. This species is vagrant on both sides of the leaf surfaces. No damage to the host was observed.

Etymology. The specific designation fasciculifolis is from the species name of host plant, fasciculifolius ; feminine in gender.

Differential diagnosis. This species is similar to Aceria astragali ( Liro, 1940) [from Astragalus alpinus L. ( Fabaceae )], but can be differentiated from the latter by lacking the median and admedian lines on the prodorsal shield (median and admedian lines present in A. astragali ).
