TYPES: Male holotype and female paratype taken in thin litter and moss-fern growth ( Scalesia , Psychotria , Chiococca, Zanthoxylym community) at the base of lava blocks on well-drained soil at an elevation of 450 m at Cerro Palada, Isla San Cristóbal , Galapagos Islands (Feb. 17, 1978; W. Reeder), deposited in TMM (57861, PBI_OON 36401).
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: This species resembles the Brazilian E. bahia in having a patterned abdomen (figs. 900, 913) and an elongated, posteriorly expanded anterior epigynal sclerite (fig. 918). Males can be distinguished by the shorter, thicker palpal femur and the absence of a thick dorsal scopula on the cymbium (figs. 907–910), females by the shorter, wider epigynal atrium (figs. 914, 918, 920).
MALE (PBI_OON 36401): Total length 1.26 (figs. 900, 901, 904). Carapace pale orange, surface of elevated portion of pars cephalica smooth, sides granulate, granulate microsculpture reaching halfway up sides; lateral margins with blunt denticles (figs. 902, 906). Eyes: ALE circular, PME squared; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 903). Sternum pale orange, without radial furrows between coxae I–II, II–III, III–IV, surface smooth, microsculpture absent (figs. 912). Chelicerae, endites, and labium pale orange. Abdomen ovoid; dorsum with striped pigmentation visible under dorsal scutum; book lung covers large, ovoid; pedicel tube medium, scutum extending far dorsal of pedicel; dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth; postepigastric scutum pale orange, sides smooth (figs. 905, 911). PMS present (compound microscope). Legs pale orange. Right and left palps symmetrical, proximal segments pale orange; embolus dark; femur enlarged (figs. 907–910); cymbium and bulb pale orange.
FEMALE (PBI_OON 36402): Total length 1.54 (figs. 915, 919, 921). Abdomen with soft portions of dorsum white, with striped pigmentation (figs. 913, 916, 917). Epigynum with middle part of atrium sunken in ventral view (figs. 914, 918, 920).
