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

Diagnosis. The male of Thymoites camaqua  new species differs from those of the other species in the shape of the carapace ( Figs. 32, 33View FIGURES 31 – 35), the palp resembles that of T. tabuleiro  new species, but differs in the patella developed ( Fig. 31View FIGURES 31 – 35), trajectory of the sperm duct in the tegulum and shape of conductor developed ( Fig. 31View FIGURES 31 – 35).The female of Thymoites camaqua  new species differs from those of the other species by the large atrium in the ventral epiginal plate ( Fig. 34View FIGURES 31 – 35) and the shape of the fertilization ducts ( Fig. 35View FIGURES 31 – 35).
