description: Escaphiella gigantea, new species Figures 570–608; map 12   
TYPE: Male holotype taken from decayed wood under bark at Tayrona-Park, Bahía de Gairaca, ca. 20 km E Santa Marta, Magdalena, Colombia (June 26, 1985; H. Müller), deposited in MHNG (PBI_OON 15582).  
ETYMOLOGY: The specific name refers to the relatively large size of these diminutive spiders.  
 DIAGNOSIS: This species seems closest to E. magna, sharing the large size and dark coloration of that species, but can be distinguished by the unpitted abdominal scuta (fig. 572), the more protuberant embolar base and longer embolus of males (figs. 594–596), and the wider anterior epigynal sclerite of females (fig. 605).   
MALE (PBI_OON 15574): Total length 3.10 (figs. 586. 587, 590). Carapace dark red-brown, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margins with blunt denticles (figs. 570, 571, 573, 588, 592). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 589). Sternum red-brown, without radial furrows between coxae I–II, II–III, III–IV, surface rugose, setae densest anteromedially, on raised portion of sternum without microsculpture; transverse groove raised medially, creating two shallow, lateral pouches (fig. 577, 598). Chelicerae (fig. 574, 575), endites, and labium dark red-brown. Endites anteromedially with large, long, spiniform tip (figs. 578, 579). Abdomen ovoid; book lung covers large, elliptical; pedicel tube medium, ribbed, scutopedicel region unmodified, scutum extending far dorsal of pedicel (figs. 580, 581, 593, 597); dorsal scutum red-brown, covering full length of abdomen, no soft tissue visible from above, middle surface finely reticulate, sides finely reticulate (fig. 572); epigastric scutum with anterior spiracles connected by groove; postepigastric scutum red-brown, sides finely reticulate (fig. 599). PMS absent (figs. 582–585). Legs dark red-brown, all tibiae with obvious microsculpture. Right and left palps symmetrical, proximal segments red-brown; embolus dark, long, on protuberant base (figs. 594– 596); femur normal size; cymbium and bulb red-brown.  
FEMALE (PBI_OON 15613): Total length 3.30 (figs. 602, 606). Sternum with microsculpture covering entire surface (fig. 607). Abdomen with soft portions of dorsum white (figs. 591, 600, 603, 604, 608). Epigynum with posterior widened anterior sclerite (figs. 601, 605).
