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) (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, 283). 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, 284).   Distribution.Only known from the typelocality ( Fig. 316). 3861775493 [332,1402,510,537] AMNH Guyana 5.2628 Tumatumari 7 -59.1483 68 69 1 1 Potaro-Siparuni holotype
