Etymology. The specific name is a noun, in Brazilian Portuguese, taken from the Tupi-Guarani Language meaning “real woods” (Ka’a = woods; eté = real) in reference to the Atlantic Forest, where this species is found; noun in apposition.
Diagnosis. Specimens of P. caete sp. nov. resemble those P. tacomare sp. nov. (Figs 67–77) by the male palps with RTA bearing more than one branch (single branched in the other species) and by the female epigyne with ag straight or slightly recurved, not projecting over the median septum (projecting in the other species). Males are distinguished from those of the latter species by the RTA with three branches (Fig. 58) and embolus tip complex, with three projections (Figs 14, 59) (RTA with two branches and embolus tip filiform in P. tacomare sp. nov.). Females are distinguished by the MS longer than wide with posterior margin at level with posterior margin of LL (Figs 54, 60) (MS wider than long with posterior margin reaching slightly more than half LL length in P. tacomare sp. nov.).
Description. Male (holotype): Coloration as in Figs 47–48. Total length 8.9. Dorsal shield of prosoma: 4.1 long, 3.4 wide. Opisthosoma: 4.6 long, 2.4 wide. Eyes: diameters: 0.29, 0.25, 0.15, 0.24; interdistances: 0.34, 0.09, 0.48, 0.36, 0.23, 0.12. Legs (1243): I: 13.2 (4.0, 2.0, 3.3, 3.0, 0.9); II: 12.6 (3.9, 2.0, 3.0, 2.9, 0.8, 12.6); III: 10.5 (3.4, 1.7, 2.3, 2.4, 0.7); IV: 13.1 (3.9, 1.5, 3.0, 3.6, 1.1). Spination follows the generic pattern except tibiae I–II: d0-1-0; v2-2-2-2-2. Palp: VTA large triangular; RTA with three acute branches with rounded tips in retrolateral view and sub squared in ventral view; ST visible between 3–5 o’clock in retrolateral view; spermophore with undulation between 11–12 o’clock; TBE hyaline, fanning out at tip; TBC reduced to a small sclerotized elevation; C hood four times longer than wide, tongue-like in ventral view; E arising from tegulum at 7 o’clock position, tip complex bearing a leaf-like projection at the embolus opening, between a long prong-like projection and a slender, laminar projection; MA slightly wider than long, widest distally, with slightly medially depressed margin (Figs 51–53, 56–59).
Female (IBSP 135183): Coloration as in Figs 49–50. Total length 10.4. Dorsal shield of prosoma: 4.7 long, 4.1 wide. Opisthosoma: 5.6 long, 3.5 wide. Eyes: diameters: 0.30, 0.30, 0.17, 0.25; interdistances: 0.40, 0.23, 0.60, 0.55, 0.27, 0.18. Legs (4213): I: 12.7 (3.8, 2.2, 3.3, 2.6, 0.8); II: 13.1 (4.1, 2.3, 3.2, 2.7, 0.8); III: 10.4 (3.4, 1.7, 2.4, 2.2, 0.7); IV: 13.4 (4.0, 1.7, 3.0, 3.6, 1.1). Epigyne: EF as wide as long, with elongate MAB on each side; LL with small lateral projections on posterior margin; MS longer than wide with posterior margin slightly curved; ag straight or slightly recurved (Figs 54, 60). Vulva: IDS with Dh much longer than wide connecting to Ds laterally; Ds irregularly shaped; FD antero-laterad (Figs 55, 61–62).
Variation. Males (n=10): total length 7.1–10.7; prosoma length 3.3–4.7; femur I length: 3.2–4.3. Females (n=10): total length 11.4–15.3; prosoma length 4.5–6.6; femur I length: 3.6–5.5.
Distribution. Known from the states of Pará, Paraíba, Pernambuco, Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, Paraná and Santa Catarina (Fig. 79).
