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, 12 View Figure , 49–53 View Figure ), 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. 10 View Figure , 56– 59 View Figure ). 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, 14 View Figure ) and the shape of fertilization ducts ( Fig. 14 View Figure ).
