DIAGNOSIS : Males resemble those of E. nye in having the embolus abruptly narrowed at the tip of the base, but have a shorter embolus (figs. 328–331); females have a posteriorly widened epigynal area including a pair of widely separated posterior depressions (fig. 341). MALE (PBI_OON 26825): Total length 1.24 (figs. 319, 320, 323). Carapace pale orange, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margins with blunt denticles (figs. 324, 325). Eyes: ALE circular, PME circular; ALE separated by less than their radius, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching (fig. 322). Sternum pale orange, without radial furrows between coxae I–II, II–III, III–IV, surface smooth, microsculpture absent (fig. 332). Chelicerae, endites, and labium pale orange. Abdomen ovoid; book lung covers small, ovoid; pedicel tube medium, ribbed, scutopedicel region unmodified, scutum extending far dorsal of pedicel (fig. 327); dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above, middle surface smooth, sides smooth (fig. 321); postepigastric scutum pale orange, sides smooth (fig. 326). PMS present (light microscope). Legs pale orange. Right and left palps symmetrical, proximal segments pale orange; embolus dark; abruptly narrowed, relatively short (figs. 328–331), femur normal size; cymbium pale orange; bulb yellow. Figs. 319–327.
