Females of M. kaieteur spec. nov. resemble those of M. jaraua spec. nov. ( Figs 173–178 ) by the vulva with internal ducts with FW postero-laterad, GP posteriad and spermathecae ovoid. They are distinguished from the latter species by the epigyne with MS narrow, three times longer than wide, widest posteriorly and EP with anterior margin reaching one fifth MS length (MS roughly two times longer than wide, widest medially and EP with anterior margin reaching half MS lenght in M. jaraua spec. nov. ). Males are unknown. Description. Female ( holotype ): Total length 14.0. Prosoma 6.3 long, 5.8 wide. Opisthosoma 7.3 long, 4.2 wide. Eyes: diameters: 0.45, 0.40, 0.26, 0.35; interdistances: 0.35, 0.24, 0.75, 0.69, 0.40, 0.35. Legs: I: 24.9 (7.0, 3.0, 6.5, 6.7, 1.7); II: 26.7 (7.7, 3.1, 7.0, 7.0, 1.4); III: 18.2 (5.2, 2.6, 4.6, 4.4, 1.4); IV: 21.1 (6.5, 2.5, 5.2, 5.3, 1.6). Epigyne: EF wider than long; MAB slightly conspicuous, embedded in EF; EP triangular, opening at posterior margin of MS; LL touching posteriorly ( Figs 184 , 191 ). Vulva: GP 3 times longer than wide, arising from ducts at first turn; SP ovoid; FD antero laterad ( Figs 185–186 , 192 ). Male: unknown. Variation. Females (n = 4): total length 10.8–18.0; prosoma length 4.5–6.5; femur I length 5.6–7.8. Distribution. Known from northern South America ( Venezuela and Guyana ) ( Fig. 315 ).
