Diagnosis This species can easily be distinguished from all other species of Stenaelurillus by the unique, hookshaped RTA that is bent laterad ( Figs 492–493 ) in the male, and by the conformation of the female copulatory organs: viz., the epigyne with two large rounded fossae and the thin, tube-shaped and straight insemination ducts directed anteriad (see Wesołowska 2014b : figs 14F–G).
