Rem.: For Prusova & al. (2001, p.51) this species is very similar to wem>S. pileatus and S. subcrassus in the body shape, but distinguished from them by the more rounded forehead in dorsal and lateral views, and by the shape and arrangement of seminal receptacles. S. flemingeri differs from S. subcrassus in its smaller size and the narrower genital segment in dorsal view. The male is distinguished from S. pileatus and S. subcrassus by the cask-shaped second urosomal segment, shape and proportion, of P5 segments including distal spine in order from proximal is in S. flemingeri 30 : 42 : 27 : 25 : 26; in S. pileatus 18 : 17 : 15 : 13 : 11; and in S. subcrassus 28 : 27 : 15 : 20 : 25; and distal segment of P5 covered with hairs (according to Giesbrecht, 1892, these segments are naked in S. pileatus and S. subcrassus.
