Diagnosis. The male of Thymoites ilhabela  new species differs from those of the other species in the shape of the carapace, with distal area forming a neck and anterior eyes in the tip of the projection ( Figs. 11, 12View FIGURES 10 – 14, 49–53View FIGURES 49 – 54), the palp resembles that of T. mirus Levi, 1964  (see Levi, 1964: fig. 34), but differs in the conductor non-pointed and the shape of embolus ( Fig. 10View FIGURES 10 – 14, 56– 59View FIGURES 55 – 60). The female of T. ilhabela  new species is close to T. mirus Levi  (see Levi, 1964: figs. 32, 33), but differs from it in the smaller spermathecae ( Figs. 13, 14View FIGURES 10 – 14) and the shape of fertilization ducts ( Fig. 14View FIGURES 10 – 14).
