Diagnosis

Males of Uaica carapiranga gen. et sp. nov. resemble those of U. uatuma gen. et sp. nov. ( Figs 12C–E View Fig , 14A–C View Fig ) 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 View Fig , 4B View Fig ) (longer than C in U. uatuma ) and by the shorter RTA, barely reaching the proximal margin of the cymbium ( Figs 3E View Fig , 5C View Fig ) (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 View Fig , 7 View Fig ) 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 View Fig , 5D View Fig ) and by the IDS loosely twisted with three turns ( Figs 4D View Fig , 5E–F View Fig ) (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 View Fig ) (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.
