The specific name means peanut in Portuguese and refers to a traditional festival (Festival do Amendoim) from Senador Guiomard, type locality of the species; noun in apposition. Diagnosis. Females of G. amendoim sp. n. resemble those of G. alpahuayo sp. n. and G. manauara by the epigyne with MS bearing pair of epigynal pockets ( Figs 4 , 15 , 77 ). They are distinguished in having the pockets separated and opening posteriorly ( Figs 15 , 24 ) (medially connected and opening anteriorly in the latter species). Males are unknown. Description. Female ( holotype ): Prosoma pale brownish orange with sub-marginal pale brown stripes and two small irregular pale brown marks at the base of cephalic region; fovea and thoracic striae pale brown; eye borders black. Chelicerae, legs and palps pale orange with small brown spots. Labium brown. Endites pale yellowish-cream, darker at base; sternum pale yellowish-orange with brown margins. Opisthosoma pale gray; dorsally with lighter lateral margins with few whitish guanine spots and two pairs of rounded brown muscle impressions; ventrally with scattered whitish guanine spots and pair of curved lines of muscle impressions; spinnerets pale yellowish orange ( Figs 20−21 ). Total length 7.5. Prosoma: 3.1 long, 3.2 wide. Opisthosoma: 4.2 long, 3.5 wide. Eyes: diameters: 0.17, 0.20, 0.15, 0.22; interdistances: 0.13, 0.06, 0.31, 0.26, 0.27, 0.24. Legs (2143): I: 13.9 (4.0, 1.4, 4.0, 3.3, 1.2); II: 15.6 (4.6, 1.5, 4.5, 3.7, 1.3); III: 11.9 (3.7, 1.2, 3.1, 2.9, 1.0); IV: 12.6 (3.7, 1.0, 3.3, 3.4, 1.2). Epigyne: epigynal field slightly wider than long with lateral muscle attachment bands; MS squared, slightly longer than wide; paired epigynal pockets two times wider than long ( Figs 15 , 24 ). Vulva: internal ducts running anteriad from CO then posteriad to SP; SP oval; FD antero-laterad (mating plugs blocking CO)( Figs 16 , 25 ). Male. Unknown. Variation. Females (n = 2): total length 7.5−8.2; prosoma length 3.0−3.1. Distribution. Only known from the type locality in northwestern Brazil ( Fig. 81 ).
