Sobekova and P. Puchala. Remarks. Based on primary description of Bernhard (in Westerboer and Bernhard 1963 ), and re-description of Vasilyeva et al. (1976) , females of Kleemannia insignis may be distinguished from those of all other members of the genus by the insertion of JV2 on soft integument; these setae are illustrated as being out but adjacent to the anterior edge of ventrianal shield. In the only Slovak specimen available for study, my examination showed that there can be an alternative position of these setae because they are both clearly on the shield, adjacent to its anterior margin. Based on the original illustrations of Fan and Li (1993) , Ameroseius marginalis perfectly fits to Kleemannia insignis from Europe (dorsal and ventral chaetotaxy, specific sculptural granulation of dorsal shield, sculpture of metapodal platelets, shape and arrangement of ventral shields, etc.). Unfortunately, differential characters for separating A. marginalis (and also A. sichuanensis ) from K. insignis given by Fan and Li (1993) are founded on variable (shape of pseudo-metasternal platelets, relative length of J2) or misinterpreted characters (in the original description of Kleemannia insignis , the number of teeth on fixed digit is stated to be five instead of four).
