Escaphiella tayrona , new species Figures 512–544 ; map 10

TYPE: Male holotype taken in decayed wood and fallen leaves at Tayrona-Park, Bahía de Gairaca , ca. 20 km E Santa Marta, Magdalena, Colombia (June 26, 1985; H. Müller), deposited in MHNG (PBI_OON 37519) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Members of this species resemble those of E. itys , especially in the degree of right palpal asymmetry (figs. 527– 534), but lack an abdominal pattern, have granulation covering almost all of the carapace (figs. 512, 513), the legs reticulate, smaller book lung covers (figs. 524, 543), a more protuberant embolar base (figs. 528– 530), and a more pentagonal epigynum (fig. 544).

MALE (PBI_OON 37494): Total length 1.63 (figs. 519, 520, 523). Carapace pale orange, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margins with blunt denticles (figs. 513, 515, 521, 526). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 522). Sternum pale orange, with radial furrows between coxae I– II, II–III, III–IV, furrow smooth, surface smooth, microsculpture absent (fig. 535). Chelicerae, endites, and labium pale orange. Abdomen ovoid; book lung covers large, ovoid; pedicel tube medium, ribbed, scutopedicel region with widely oval, granulated scutal ridge (figs. 517, 518), scutum extending far dorsal of pedicel, with straight, horizontal scutal ridge just above pedicel (fig. 516, 524); dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth (fig. 514); postepigastric scutum pale orange, sides smooth (fig. 525). PMS present (compound microscope). Legs pale orange. Right palp consistently different from left palp, about half its size (figs. 527–534), proximal segments pale orange; embolus dark; femur normal size; cymbium and bulb pale orange.

FEMALE (PBI_OON 37494): Total length 1.69 (figs. 512, 537, 538, 540, 542). Abdomen with soft portions white (figs. 536, 539); epigastric scutum carinated anteriorly (figs. 541, 543). Epigynum pentagonal (fig. 544).
