Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. The male of Thymoites piratini  new species differs from those of the other species by the pointed distal area of the carapace ( Figs. 37, 38View FIGURES 36 – 40, 61–66View FIGURES 61 – 66) and the palp with cymbium with pointed apex ( Fig. 36View FIGURES 36 – 40, 68– 70View FIGURES 67 – 72).The female of Thymoites piratini  new species is close to Thymoites ilhabela  new species, but differs by the shorter fertilization ducts ( Fig. 40View FIGURES 36 – 40) and the shape of copulatory ducts ( Figs. 39, 40View FIGURES 36 – 40).
