Specimens examined. Two females, Kostanay Region, Kazakhstan, 53°15ʹN, 66°28ʹE, 5 October 2019, A.K. Is-sakova coll., from soil (in TSUMZ) .

Remarks. Lasioseius ometes was described from house sweepings in the Netherlands ( Oudemans, 1903). It is now recorded in Kazakhstan for the first time, from soil. The species is easily recognised by the strongly sclerotised and reticulated dorsal shield, bearing 36 pairs of lanceolate-pencillate setae ( Figs 16 & 18 ) and posterior margin of sternal shield with a deep concavity reaching level of setae st2 ( Figs 17 & 19 ).
