Remarks — Unlike previous studies, measurements of idiosomal setae and organotaxy are given in this study for adult males and mobile immature stages. Shape and arrangement of idiosomal setae closely resemble the re-description of Arutunjan (1977), with slight differences, e.g. larva with an entire opisthonotal shield in this study but divided in that study. Femur I of larva and protonymph with 10 setae as opposed to nine setae in Arutunjan (1970, 1972).
