Figs 280–284 View FIGURES 280–282 View FIGURES 283–284 , 316 View FIGURES 315–318

Type material. Holotype: GUYANA: Potaro-Siparuni: ♀, Tumatumari [5.2628, ‑59.1483], no date ( AMNH). GoogleMaps

Note. The original label wrongly refered Tumatumari as being in Brazil.

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

Diagnosis. Females of M. tumatumari spec. nov. resemble those of M. martinique spec. nov. ( Figs 200–202 View FIGURES 196–202 ) and M. trinitatis comb. nov. ( Figs 269–274 View FIGURES 269–274 ) by the vulva with GP arising from ducts close to SP, not at first turn. They are distinguished from both species by the EP with anterior margins greatly surpassing half MS length and opening slightly anterior to posterior margin of MS ( Fig. 280 View FIGURES 280–282 ) (EP with anterior margins not surpassing half MS length and opening at posterior margin of MS in M. martinique spec. nov. and M. trinitatis comb. nov.).

Description. Female (holotype): Total length 13.6. Prosoma 5.6 long, 5.2 wide. Opisthosoma 7.9 long, 5.3 wide. Eyes: diameters: 0.43, 0.37, 0.30, 0.36; interdistances: 0.33, 0.20, 0.50, 0.56, 0.32, 0.20. Legs: I: 26.5 (7.7, 2.8, 7.0, 7.1, 1.9); II: 28.5 (8.0, 3.2, 7.7, 7.7, 1.9); III: 20.3 (6.2, 2.5, 5.0, 5.0, 1.6); IV: 22.7 (7.0, 2.1,.5.8, 6.0, 1.8). Spination follows the generic pattern except metatarsus IV: p1-1-1. Epigyne: EF longer than wide; MAB inconspicuous; MS slightly longer than wide with posterior margin with medial concavity; EP triangular, 1.5 times longer than wide; LL touching posteriorly ( Figs 260 View FIGURES 260–264 , 283 View FIGURES 283–284 ). Vulva: internal ducts with FW postero laterad, dilated; GP elongate, three times longer than wide, anteriad; SP irregular-shaped with few lateral folds; FD antero-laterad ( Figs 281–282 View FIGURES 280–282 , 284 View FIGURES 283–284 ).

Distribution. Only known from the type locality ( Fig. 316 View FIGURES 315–318 ).
