Remarks.

The first European finding of the genus Sinoseius   was that of Huhta and Karg (2010) from Finland (bottom of straw shed and grass in garden of old farm). Fenďa and Lukáš (2014) found the species in a frozen nest of Sitta europaea   Linnaeus, 1758 ( Aves  , Passeriformes  ), in a nest box, and in a soil sample from the dysphotic zone of a cave. I have compared the holotype and one paratype of Sinoseius pinnatus   with the specimens reported from Slovakia by Fenďa and Lukáš (2014), and found that they are clearly conspecific. According to Huhta and Karg (2010), Sinoseius lobatus   and S. pinnatus   can be distinguished by the features presented as follows: in S. lobatus   , dorsal setae "remarkably long", j5 = j5-j6, j6 > j6-J2, tines of dorsal setae strong (depicted seven pairs of tines), anal shield distinctly wider than long (length/width = 2:3), corniculi bifid; in S. pinnatus   , dorsal setae „moderate“, j5 = 2/3 × j5-j6, j6 < j6-J2, tines of dorsal setae very thin (depicted up to 19 instead of 9-10 pairs of tines), anal shield only a little wider than long, corniculi distally trifid. It is clear that the distinctions made in the original descriptions and differential diagnosis of S. pinnatus   by Huhta and Karg (2010) are based on characteristics that are misinterpreted (form of setae and corniculi) or vary considerably (relative length of dorsal setae, proportion of anal shield), and I do not hesitate to propose the synonymy of both mentioned species, although no types of S. lobatus   were examined in this study. When compared the Slovak specimens of Sinoseius   with quite adequate original illustrations of S. lobatus   from China, it was not possible to find reliable distinguishing characters between them.
