The specimens from Bananeiras ( Paraíba) have 9 femoral spines, as well as the holotype( Fig. 17E). 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. bicolorcornutafrom other localities have between 13–19 femoral spines, similar to  T. gladiata, but this latter species can have 24 spines ( Fig. 27E). Consequently, this characteristic cannot be used to separate species ( Table 1) 2236308295 2008-04-15 2008-05-17 2008-04-15 entomological aspirator CC, UFRN BC Bellini Brazil 314 -6.6666665 " Cachoeira da Capivara " farm 1304 -35.75 Cacimba de Dentro municipality 17 218 3 1 1 1 Paraiba state 2236308291 2014-03-17 entomological aspirator CC, UFRN DD Silva Brazil 105 -7.105 urban region 21 -35.234165 Sape municipality 17 218 15 Paraiba 2236308305 2014-03-19 entomological aspirator INPA DD Silva Brazil 474 -6.736667 State Ecological Reserve of " Goiamunduba " 21 -35.609722 Bananeiras 17 218 1 Paraiba 2236308304 2014-04-22 entomological aspirator CC, UFRN NN Godeiro & DD Silva Brazil 123 -5.588889 Lajedo de Soledade 21 -37.831387 Apodi municipality 17 218 37 Rio Grande do Norte 2236308296 2015-06-21 entomological aspirator CC, UFRN NN Godeiro Brazil 39 -6.226861 " Pipa " Beach 1 -35.07497 Tibau do Sul municipality 17 218 22 Rio Grande do Norte 2236308303 2014-04-18 2014-04-20 2014-04-18 entomological aspirator CC, UFRN NN Godeiro & DD Silva Brazil 180 -4.9597497 Quixada municipality 1 -39.007168 Quixada municipality 17 218 31 Ceara
