Figs 280–284 , 316 Type material. Holotype : GUYANA : Potaro-Siparuni : ♀ , Tumatumari [ 5.2628 , ‑59.1483 ], no date ( AMNH ). 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 ) and M. trinitatis comb. nov. ( Figs 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 ) (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. ). FIGURES 280–282. Meri tumatumari spec. nov. , female (AMNH, holotype) (280 epigyne, 281 vulva, 282 schematic course of internal duct system). EP—epigynal pocket; FD—fertilization duct; ft—first turn of duct system; GP—glandular projection; LL—lateral lobe; MS—median septum; SP—spermathecae. Scale lines: 1 mm. 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 type locality ( Fig. 316 ).
