 TYPE: Male holotype from 2 mi SE Niltepec, 16 ° 329N, 94 ° 339W, Oaxaca, Mexico (Aug. 16, 1966; J., W. Ivie), deposited in AMNH (PBI_OON 26821).   
ETYMOLOGY: The specific name refers to the coloration.  
 DIAGNOSIS: This species resembles E. iguala but can be distinguished by the olive coloration of the abdominal scuta, the more pronounced carapace sculpturing (fig. 387), the distally expanded male palpal femora (fig. 393), and the more anteriorly situated anterior epigynal sclerite and the laterally extended lateral epigynal sclerites of females (fig. 398).   
MALE (PBI_OON 26821): Total length 1.33 (figs. 385, 386, 392). Carapace pale orange, surface of elevated portion of pars cephalica smooth, sides granulate; lateral margins with blunt denticles (fig. 387). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 388). Sternum pale orange, without radial furrows between coxae I–II, II–III, III–IV, surface smooth, microsculpture absent (fig. 391). Chelicerae, endites, and labium pale orange. Abdomen ovoid; book lung covers small, ovoid; pedicel tube medium, ribbed, scutopedicel region with faint, widely oval scutal ridge, scutum extending far dorsal of pedicel (figs. 389, 397); dorsal scutum olive-green, covering more than 3/4 of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth; postepigastric scutum olive-green, sides smooth (fig. 390). PMS present as single median projection (light microscope). Legs pale orange. Right and left palps symmetrical, proximal segments pale orange; embolus dark; femur enlarged, with two rows of small spines (figs. 393–396); cymbium and bulb pale orange.  
FEMALE (PBI_OON 26820): Total length 1.43 (figs. 400, 401, 403, 404). Abdomen with soft portions of dorsum white (figs. 399, 402); scutopedicel region unmodified; anterior part of epigastric scutum with scutal ridge (figs. 405, 406). Anterior epigynal sclerite restricted to anterior portion of wide epigynum (fig. 398).
