Diagnosis
Males of Uaica carapiranga gen. et sp. nov. resemble those of U. uatuma gen. et sp. nov. (Figs 12C–E, 14A–C) by the palps with a tegulum bearing an indentation at the base of the E, but are distinguished by the shorter E, same length as C (Figs 3D, 4B) (longer than C in U. uatuma) and by the shorter RTA, barely reaching the proximal margin of the cymbium (Figs 3E, 5C) (surpassing the proximal margin of the cymbium by almost half its length in U. uatuma). Females resemble those of U. juruena gen. et sp. nov. (Figs 6C–D, 7) by the epigyne with MS shaped as an inverted Y, bearing median EP (MS elongate with anterior EP in U. juruena). They are distinguished from those of the latter species by the LL not touching posteriorly, by the EP roughly as wide as long (Figs 4C, 5D) and by the IDS loosely twisted with three turns (Figs 4D, 5E–F) (LL touching posteriorly, EP almost 3 × as long as wide and IDS tightly coiled with five turns in U. juruena). Additionally, it is distinguished from all congeners by having two GPs (Fig. 5E–F) (only one in the other species).
Etymology
The specific epithet refers to the type locality of the holotype, in the region of Juruti, Pará; noun in apposition.
