Deposition. NIBRIV0000901668.

GenBank accession No. MH 983584 for CO1.

World distribution. Spain, Central and Southern Croatia, Dalmatia and Southern Turkmeni, Malaysia, and Korea.

Diagnosis. Size about 90 - 125 × 30 - 40 μm. The genital shield is flat with rounded front edge. In male, the genital shield is fused with the sternal shield. Ventrianal shield of female mite is with rounded sides, transverse lines ( Fig. 11). Unlike the female, surface of the male’s anal shield has a reticulate pattern instead of a distinct one.
