Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Originally described from a single female collected from the roots of Achillea millefolium in Tallin Estonia..The poor ionitial description causesd several authors to designate it as species inquirendae. However, subsequent analyses and ITS-rRNA sequences support the validity of the species (Subbotin et al., 2010).
