TYPES: Male holotype and female allotype from Central, Bahia, 11 ° 019–11 ° 199S, 41 ° 479– 42 ° 109W, Brazil (July 15–31, 2002; E. Ramos, F. Cunha), deposited in IBSP (67411, 67406, PBI_OON 27755, 27756) .

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

DIAGNOSIS: This species resembles E. itys and E. aratau in having a patterned abdomen (figs. 725, 744), but males have a denser distal scopula on the palpal cymbium (figs. 734–737), and females have a distinctive, posteriorly expanded anterior epigynal sclerite (figs. 745, 749).

MALE (PBI_OON 27756): Total length 1.90 (fig. 725). Carapace pale orange, surface of elevated portion of pars cephalica granulate, sides granulate, granulate microsculpture obvious, covering complete surface of carapace; lateral margins with blunt denticles (figs. 726, 731). Eyes: ALE oval, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 729). Sternum pale orange, with radial furrows between coxae I–II, II–III, III–IV, furrow smooth, surface finely reticulate, microsculpture covering entire surface, transverse groove raised medially, creating two shallow lateral pouches (fig. 738). Chelicerae, endites, and labium pale orange. Abdomen ovoid; dorsum with striped pigmentation visible under dorsal scutum; book lung covers large, ovoid; pedicel tube medium, ribbed (fig. 728), scutopedicel region unmodified, scutum extending far dorsal of pedicel, small scutal ridge present above pedicel (figs. 730, 732); dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface reticulate, sides reticulate; postepigastric scutum pale orange, sides reticulate (figs. 727, 733, 739). PMS present (compound microscope). Legs pale orange; femora and tibiae obviously striated. Right and left palps symmetrical, proximal segments pale orange; embolus dark; femur normal size; cymbium pale orange, apically with dense patch of setae (figs. 734–737); bulb pale orange.

FEMALE (PBI_OON 27755): Total length 2.00 (figs. 742, 743, 746, 747). Abdomen with soft portions of dorsum white, striped pigmentation visible under ventral scutum (figs.

740, 741, 744, 748). Anterior epigynal sclerite greatly expanded posteriorly (figs. 745, 749).
