Remarks. The modified legs of T. bicolorcornuta  were originally described from a single, apparently subadult, male specimen, and for this reason the variation in number of femoral spines of leg I are described here. The specimens from Bananeiras (Paraíba) have 9 femoral spines, as well as the holotype ( Fig. 17EView FIGURE 17). This number may be fewer in subadult males from Cacimba de Dentro (Paraiba) and Tibau do Sul (Rio Grande do Norte), as leg I has 4 and 7–8 femoral spines in these specimens respectively. Adults of T. bicolorcornuta  from other localities have between 13–19 femoral spines, similar to T. gladiata  , but this latter species can have 24 spines ( Fig. 27EView FIGURE 27). Consequently, this characteristic cannot be used to separate species ( Table 1)
