Diagnosis. Rostrum 1.5–2.0 times as long as wide. Median carina erect, with clear dentition. Major cheliped, palm lateral and mesial faces tuberculate near base of fingers; distolateral margin with single blunt tooth in gape; fixed finger 0.6 length of upper margin of palm, cutting edge with broad blade over proximal half, irregular beyond; dactylus cutting edge with basal molar-like tooth, notch and straight beyond. Minor cheliped, palm upper margin as long as greatest width; distolateral margin with prominent bifid triangular tooth at base of dactylus. Uropod endopod anterolateral apex acute, with 1 or few small teeth.

Distribution. Pacific coast, Panama (Albatross stn 3358), 465 fm (851 m) (type locality); Ecuador, Galapagos Is, 717 m ( Kensley, 1996), 1123–1378 m (Hendrickx, 2008).

Remarks. The species was redescribed by Kensley (1996) and compared by us with E. antillensis above. Hendrickx (2008) illustrated variation in the dentition of the rostrum of five syntypes and recorded the species from much greater depths than previously.
