Figs 62–71 , 89

Sadala keyserlingi Simon, 1880: 323 (only 2 female syntypes, misidentification, ex MNHN 2459 ).

Type material. Holotype: BRAZIL: Amazonas : ♀, Tabatinga , Comando de Fronteira do Solimões, 8 o Batalhão de Infantaria (-4.2458, -69.9233), 4 November 2016, L.S. Carvalho leg. (CHNUFPI 2454) . Paratype: COLOMBIA: 1♀, Río Suarez (no specific locality), 11–17 August 1946, no leg. ( AMNH) .

Additional material examined. BRAZIL: Amazonas: 2♀, Tefé [‑3.3667, ‑64.7000], no date (ex MNHN 2459 ) .

Etymology. The specific name refers to the type locality; noun in apposition.

Diagnosis. Females of S. tabatinga spec. nov. resemble those of S. keyserlingi ( Figs 27–29 ) by the vulva with FW dilated, at least three times wider from CO to first turn than between first and second turns ( Fig. 63 ). They are distinguished from the latter species by the epigyne with slightly pear-shaped MS ( Figs 62 ) (triangular in S. keyserlingi ). Males are unknown.

Description, Female (holotype): Total length 15.3. Prosoma: 6.6 long, 6.2 wide. Opisthosoma: 8.5 long, 4.7 wide. Eyes: diameters: 0.55, 0.40, 0.35, 0.40; interdistances: 0.35, 0.30, 0.65, 0.72, 0.40, 0.35. Legs: I: absent; II: 31.1 (9.0, 3.5, 8.1, 8.2, 2.3); III: 22.2 (6.7, 2.7, 5.7, 5.5, 1.6); IV: 23.9 (7.5, 2.7, 6.3, 5.6, 1.8). Spination follows the generic pattern except patellae I–IV: d0. Epigyne: EF slightly wider than long; MAB embedded in EF; MS almost two times longer than wide, widest medially, slightly constricted anteriorly; TP slightly wider than long; LL touching posteriorly ( Figs 62 , 68 ). Vulva: FW posteriad; GP as wide as long, arising from ducts at second turn; SP irregularly rounded; FD antero laterad ( Figs 63–64 , 69 ).

Male: Unknown.

Variation. Females (n = 4): total length 15.3–18.5; prosoma length 6.6–7.5; femur I length 8.3–8.9. Epigyne: MS slightly shorter, less than two times longer than wide; TP slightly anterior to posterior margin ( Figs 65 , 70 ). Vulva: internal ducts with FW more dilated covering second turn and GP ( Figs 66–67 , 71 ).

Distribution. Northwestern South America, in Colombia and Brazil (Amazonas) ( Fig. 89 ).
