Etymology. The specific name is taken from the Tupi-Guarani language referring to a type of sugar cane that was widely cultivated in the Brazilian subregion known as “Zona da Mata”, a stretch of land extending from eastern Rio Grande do Norte to southern Bahia, composed mainly of Atlantic Forest, where this species occurs; noun in apposition.

Diagnosis. Specimens of P. tacomare sp. nov. resemble those P. caete sp. nov. ( Figs 56–62 View FIGURES 56–62 ) 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 two branches and embolus tip filiform ( Figs 68–69 View FIGURES 67–71 , 73–74 View FIGURES 72–77 ) (RTA with three branches and embolus tip complex, with projections in P. caete sp. nov.). Females are distinguished by the MS wider than long with posterior margin reaching slightly more than half LL length ( Figs 70 View FIGURES 67–71 , 75 View FIGURES 72–77 ) (MS longer than wide with posterior margin at level with posterior margin of LL in P. caete sp. nov.).

Description. Male (holotype): Coloration as in Figs 63–64 View FIGURES 63–66 . Total length 12.2. Dorsal shield of prosoma: 6.0 long, 5.0 wide. Opisthosoma: 6.0 long, 3.7 wide. Eyes: diameters: 0.42, 0.35, 0.22, 0.33; interdistances: 0.30, 0.20, 0.50, 0.55, 0.25, 0.13. Legs (4/123): I: 17.4 (5.2, 2.8, 4.5, 3.8, 1.1); II: 16.6 (5.2, 2.6, 4.1, 3.7, 1.0); III: 13.6 (4.4, 2.2, 3.0, 3.1, 0.9); IV: 17.4 (5.1, 2.0, 4.0, 4.9, 1.4). Spination follows the generic pattern except tibiae I–II: v2-2-2- 2-2; tibia III: d0; metatarsus II: p1-1-0; metatarsus III: p1-1-0. Palp: VTA small, triangular; RTA with two branches with pointed tips in retrolateral view and curled in ventral view; ST not visible in ventral view; spermophore with pronounced undulation between 6–7 o’clock, close to embolus base; TBE long, with pointed tip; TBC reduced to small sclerotized area; C hood four times longer than wide, twisted in ventral view; E arising from tegulum at 7 o’clock position, gradually narrowing towards filiform tip; MA cup-shaped, distally rounded, longer than wide ( Figs 67–69 View FIGURES 67–71 , 72–74 View FIGURES 72–77 ).

Female (IBSP 85206, paratype): Coloration as in Figs 65–66 View FIGURES 63–66 . Total length 12.0. Dorsal shield of prosoma: 5.3 long, 4.3 wide. Opisthosoma: 6.5 long, 3.5 wide. Eyes: diameters: 0.35, 0.30, 0.20, 0.27; interdistances: 0.34, 0.22, 0.56, 0.50, 0.26, 0.15. Legs (4123): I: 13.5 (4.0, 2.5, 3.4, 2.7, 0.9); II: 13.3 (4.1, 2.4, 3.1, 2.8, 0.9); III: 11.1 (3.5, 2.0, 2.4, 2.4, 0.8); IV: 13.8 (4.0, 1.6, 3.2, 3.9, 1.1). Spination follows the generic pattern except femur II: r0-0-1; femur III: p1-0-0; r1-0-0; tibiae I–II: v2-2-2-2-2. Epigyne: EF roughly as wide as long, widest medially with one long MAB on each side; LL with small triangular projections laterally on posterior margin; MS wider than long; ag straight or recurved ( Figs 70 View FIGURES 67–71 , 75 View FIGURES 72–77 ). Vulva: IDS with Dh with two chambers connecting to Ds by elongate duct; Ds rounded; FD antero-laterad ( Figs 71 View FIGURES 67–71 , 76–77 View FIGURES 72–77 ).

Variation. Females (n=9): total length 12.0–17.0; prosoma length 5.3–6.8; femur I length 4.0–5.3.

Distribution. Known from the states of Paraíba, Sergipe, Alagoas and Bahia, northeastern Brazil ( Fig. 81 View FIGURES 78–81 ).
