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