( MUSM).   Etymology.The specific name refers to the collection locality of the holotype, taken from the Tupi Guarani Language, meaning “to glide soundlessly”; noun in apposition.   Diagnosis.Males of  M. abuna  spec. nov.resemble those of  M. martinique  spec. nov.( Figs 196–199) by the palp with embolus bearing small, tubercle-like subdistal projection and large membranous area ( Fig. 106). They are distinguished from the latter species by the PTA distally rounded, RTA gradually tappering and embolus bulging prolaterally at base ( Figs 103–105) (PTA triangular, RTA abruptly narrowed medially and embolus without prolateral bulge at base in  M. martinique  spec. nov.). Females resemble those of  M. aparia  spec. nov.( Figs 118–120) by the epigyne with MS wider than long and EP rectangular or squared, and vulva with FW dilated, mediad. They are distinguished from the latter species by the EP wider than long or as wide as long ( Fig. 107, 110) and vulva with GP postero laterad ( Fig. 108) (EP longer than wide and GP antero-mediad in  M. aparia  spec. nov.).   Description. Male (MZSP 34926, paratype):Total length 11.0. Prosoma: 5.5 long, 5.3 wide. Opisthosoma: 5.3 long, 3.7 wide. Eyes: diameters: 0.45, 0.39, 0.26, 0.35; interdistances: 0.31, 0.10, 0.50, 0.54, 0.33, 0.20. Legs: I: 30.4 (9.1, 3.2, 8.9, 9.1, 2.1); II: 34.7 (9.9, 3.3, 9.7, 9.8, 2.0); III: 24.2 (7.3, 2.4, 6.4, 6.3, 1.8); IV: 27.2 (7.9, 2.6, 7.1, 7.6, 2.0). Spination follows the generic pattern except tibia IV: d0; patella IV: p1, r1. Palp: PTA as long as wide; RTA triangular, as long as wide; cymbium with small retroproximal projection; subtegulum visible between 9 and 12 o’clock in ventral view; tegulum slightly protruding over conductor base; conductor widest at base, distally fanned; embolus gently curving subdistally ( Figs 103–106, 113–115).   FIGURES 107–112.  Meri abuna  spec. nov., female, 107–109 (ex MNHN 2459) (107 epigyne, 108 vulva, 109 schematic course of internal duct system); 110–112 (IBSP 6618) (110 epigyne, 111 vulva, 112 schematic course of internal duct system). CO—copulatory opening; 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.   FIGURES 113–117.  Meri abuna  spec. nov.113–115 male (MZSP 34926, paratype) left palp (113 prolateral, 114 ventral, 115 retrolateral); 116–117 female (MZSP 35006, paratype) (116 epigyne, 117 vulva). Scale lines: 1 mm.  Female (IBSP 6618, paratype):Total length: 12.4. Prosoma: 5.4 long, 5.1 wide. Opisthosoma: 6.7 long, 3.4 wide. Eyes: diameters: 0.41, 0.35, 0.26, 0.35; interdistances: 0.32, 0.25, 0.62, 0.57, 0.33, 0.20. Legs: I: 23.0 (7.0, 2.7, 6.0, 5.7, 1.6): II: 24.4 (7.3, 2.9, 6.7, 6.1, 1.4); III: 17.9 (5.7, 2.3, 4.5, 4.1, 1.3); IV: 20.0 (6.1, 2.2, 5.1, 5.1, 1.5). Spination follows the generic pattern except patella II–III: p1. Epigyne: EF wider than long; MAB slightly conspicuous, embedded in EF; EP with anterior margin not reaching half MS length; LL touching posteriorly ( Fig. 107). Vulva: GP longer than wide, arising from ducts at first turn; SP ovoid; FD anteriad ( Figs 107–109).  Variation.Males (n = 4): total length 9.4–12.7; prosoma length 4.5–5.6; femur I length 7.4–9.1. Females (n = 10): total length 12.4–19.2; prosoma length 4.9–6.6; femur I length 6.0–8.0. Coloration pattern in females can be generally darker. Epigyne can have MS more V-shaped with EP slightly anterior to MS posterior margin ( Figs 110, 116) and vulva can have SP more elongated oval ( Figs 111, 117).   Distribution.Known from northwestern South America, in Ecuador, Peruand Brazil( Fig. 317). 3861775308 2011-06-03 R Y.
