They resemble species of  Caayguara in having only two pairs of ventral spines on tibiae I−II but are distinguished in having 3−5 escort setae on the chelicerae (Fig. 1A) (only one in  Caayguara), a single, distal RTA in the male palps (Figs 5C, 9C, 11C, 14C) and an epigynal pocket in the female epigyne (Figs 5D, 7A, 14D) (RTA medial, complex, with projections and epigynal pocket absent in  Caayguara). They resemble species of  Nungara,  Sadala and  Meri by the number of escort setae in the chelicerae (between 3−10) (Fig. 1A), the male palps with a single, distal RTA (Figs 5C, 9C, 11C, 14C) and the female epigyne with a median septum bearing an epigynal pocket or a triangular projection (Figs 5D, 7A, 14D). They are distinguished from the latter genera by the presence of only two pairs of ventral spines on tibiae I−II. Additionally, they are distinguished from  Sadala by the female epigyne with a median septum bearing a triangular epigynal pocket (Figs 5D, 7A, 14D) (triangular projection in  Sadala), from  Nungara by the long and median conductor in the male palp (Figs 5B, 9B, 11B, 14B) (apical and guttershaped in  Nungara) and from  Meri by the embolus smooth and slender, without projections (Figs 5B, 9B, 11B, 14B) (with projections and membranous areas bearing needle-like extensions in  Meri).</p><p>Etymology</p><p>The generic epithet refers to a character in a folk tale of the Karajá and Apinaye peoples from central and northern Amazonia. According to the story,  Uaica was a bullied boy who sought refuge in the forest and, because of the kindness in his heart, received the gift of healing from Sinaa, the Jaguar Man; gender is masculine; noun in apposition.</p><p>Description</p><p>Total length of males 5.4−7.6, of females 5.9−10.8.

Clypeus low, less than AME diameter. Chelicerae longer than wide with three promarginal teeth, median one largest, and 4−5 retromarginal teeth, three similar sized, the rest smaller; intermarginal denticles present mostly at base of furrow.

Spination in males: femora I−III: p1-1-1; d0-1-1; r1-1-1; femur IV: p1-1-1; d0-1-1; r0-0-1; patellae I−II: p1; r1; tibiae I−II: p1-0- 1; d1-0-1; r1-0-1; v2-2-0; tibiae III−IV: p1-0-1; r1-0-1; v2-2-0; metatarsi I−III: p1-1-0; r1-1-0; v2-2- 0; metatarsus IV: p1-1-1; r1-1-0; v2-2-0; palp: femur: p0-0-1; d0-1-2; r0-0-1; patellae: p1; r1; tibiae: p2-1-0; d1-0-0; r1-0-0. Spination in females as in males except tibiae I–II: d0; metatarsi IV r1-1-1. Trochanter I–IV with distal ventral margin deeply notched (Fig. 1D). Metatarsi I–IV distally with dorsal trilobate membrane with median hook slightly larger than lateral projections (Fig. 1E). Tarsi and anterior half of metatarsi scopulate. Trichobothria present on dorsal side of tibiae, metatarsi and tarsi, arranged in two or more rows on tarsi and one on metatarsi. Bothrium with dorsal plate with one distal grove, projected over smooth basal plate (Fig. 1F). Tarsal organ capsulate with slightly oval opening (Fig. 2A), located dorsally on distal third of leg metatarsi. Leg tarsi with pair of pectinate claws with 12–15 very slightly curved teeth and claw tufts (Fig. 2B–D). Female palpal claw with 4–5 short, slightly curved teeth (Fig. 2E). Opisthosoma oval, longer than wide. Male epiandrium bearing epiandrous spigots in small, scattered bunches (Fig. 2F). Six spinnerets: anterior lateral spinnerets contiguous, conical and bi-segmented. Anterior median spinnerets short and truncated. Posterior lateral spinnerets conical and bi-segmented. Male palp: tibia elongate, slightly shorter than cymbium with three prolateral spines, one dorsal spine and one retrolateral spine; ventral tibial apophysis absent; RTA single, inserted distally on tibia (e.g., Figs 3C, 3E, 12C, 12E); cymbium elongate with large oval alveolus and elongate dorsal scopula; subtegulum smooth, slightly prolateral; tegulum oval, smooth or indented at base of E; C hyaline, same width throughout, inserted medially on tegulum; E without projections, slender, tapering towards tip or filiform, arising from tegulum between 8−9 o’clock or between 5−6 o’clock (e.g., Figs 3D, 8D, 10D, 12D). Female epigyne: EF as long as wide or slightly longer than wide; muscle attachment bands absent; LL smooth, with no projections, partially covering MS; MS bearing triangular EP and lateral sclerotized rims (Figs 4C, 6C, 13C). Vulva: IDS running anteriorly as double helix; GP arising from anterior most turn; spermathecae not differentiated; FD short and hook-shaped (Figs 4D, 6D, 13D).</p><p>Included species</p><p>Uaica carapiranga gen. et sp. nov.,  U. juruena gen. et sp. nov.,  U. karipuna gen. et sp. nov.,  U. mapia gen. et sp. nov.,  U. uatuma gen. et sp. nov.</p><p>Distribution</p><p>Northern Brazil, Amazonian region, states of Amazonas, Pará, Rondônia and Mato Grosso (Fig. 15).</p></div>	https://treatment.plazi.org/id/03CACF3D1849021FF597FD72B3517882	Public Domain	No known copyright restrictions apply.

(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).</p><p>Etymology</p><p>The specific epithet refers to the type locality of the holotype, in the region of Juruti, Pará; noun in apposition.</p><p>Type material</p><p>Holotype BRAZIL – Pará State • ♂; Juruti; <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=-56.2082&amp;materialsCitation.latitude=-2.4728" title="Search Plazi for locations around (long -56.2082/lat -2.4728)">Platô Carapiranga, Linha 168E</a>; 2.4728º S, 56.2082º W; 9 Feb. 2007; J.A.P.
