Etymology. The species epithet is in honor of Nora Alvarez, (spouse of DW) for her support.
Diagnosis. Males of E. norae can be distinguished from those of their congeners by the shape of palpal bulb (Figs 2 A–C), which presents a distinct embolus tip, with a small keel on the dorsal face. Females are recognized by the flat shape of spermathecae receptacles (Figs 2 G, H).

Basal segment of chelicerae with 11 teeth. Labium subquadrate, with more than 200 cuspules. Maxillae with more than 120 cuspules, each one. Thoracic fovea straight, narrow. Spines: Palp: femur (d) 0-0-p2, tibia (p) ap1, (r) 12 thick spines. Legs: I: femur (d) 0-0-p1,patela (v) 2, tibia (p) 0-0-1, (r) 2-2-1, metatarsus (v) 2-0-ap2; II: femur (d) 0-0-p2, patela (v) 2, tibia (v) 4-2- 1-ap3, (p) 0-1-1, metatarsus (v) 2-1-ap1, (p) 1-1-ap1, (r) 0-1-ap1; III: femur (d) p1-p2-p1, patella (p) 1, tibia (r) 1- 0-1, (v) 2-2-ap2, (p) 1-1-2-ap1, metatarsus (r) 1-ap1, (v) 3-2-ap3, (p) 1-1-ap1; IV: femur (d) 0-0-r1, tibia (v) 2-2- ap3, (r) 1-1-1,(p) 1-01-1 metatarsus (v) 2-3-ap3, (p) 1-1-ap1, (r) 1-0-1-ap1. Palpal bulb with short embolus, single serrated small keel on ventral surface, narrow keel on dorsal surface near embolus (Figs 2 A–C). Palpal tibia swollen, with long spines disposed in two rows (Figs 2 E, F). Retrolateral branch of tibial spur very long, tapering, with small spine on its midlength, prolateral branch longer than contiguous spine (Fig. 2 D). Metatarsus I bends retrolaterally to tibial spur. Metatarsal scopulae extent (ventral surfaces only): I and II, for almost entire length; III, for more than distal half; IV, for less than half. Tarsal scopulae (ventral surfaces only): I–II entire; III–IV divided by longitudinal band of thick setae. Paired tarsal claws with row of small teeth.
