Figs 6–10; Table 3
Diagnosis
Males differ from those of J. paru gen. et sp. nov. and J. butantan gen. et comb. nov. by the absence of PI on the palpal bulb (Figs 7, 8A–B) and in the absence of a retrolateral process on the palpal tibia (Fig. 6E). Additionally, males differ from those of J. butantan in the morphology of PA wide and dentate (acute and not dentate in J. butantan) and in the absence of PS. Female unknown.
Etymology
The specific epithet is a noun in apposition which refers to an ancestral indigenous city located in a region later known as El Dorado.
