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