Etymology. The specific name is a noun and refers to the type locality.

Diagnosis. The males of T. onca   sp. nov. resemble those of T. xingu   sp. nov. ( Fig. 140) in the bifurcated apex of the median apophysis (MA) ( Figs 111, 112), but can be distinguished by the presence of a median curvature on the median apophysis ( Fig. 112) and by the lamellar base and slender tip of the ental branch of RTA ( Fig. 114). The females resemble those of T. hirsutochela   sp. nov. ( Fig. 104) in the median projection of the middle field of epigynum ( Fig. 107), but can be distinguished by the deep lateral excavation on the middle field ( Fig. 107) and by the rounded head of spermathecae ( Fig. 109).
