Type material. Female holotype and 3 female paratypes , UKRAINE : Crimea, “Cape Martyan” Nature Reserve, in soil under grass, 10 March 2010 , coll. A. A. Khaustov. Etymology. The species name refers to very thick setae e of the new species. Differential diagnosis. The new species is very similar to B. latipilosa ( Rack, 1967 ) . Both species have distinctly thickened setae e , short and simple setae on posterior sternal plate, very short setae ps 2, and small simple claw on tibiotarsus I. The new species differs by smooth, longer and thicker setae e (in B. latipilosa setae e with several barbs and distinctly shorter and thinner), by distinctly longer setae c 1, d , f , and by setae v”TiIV distinctly shorter than pl”TaIV (in B. latipilosa setae v”TiIV longer than pl”TaIV ).
