Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.119, Fig.9]. Female (from Gulf of Mexico): a, forehead (left side); b, urosome (left side); c, genital somite (left side); d, idem (dorsal view); e, idem (right side); f, idem (ventral view); g, first leg (anterior); h, second leg (anterior). Nota: Similar in habitus to E. concinna. Rostrum only slightly curved backward. Distal end of prosome on each side broadly rounded in both dorsal and lateral view. Dorsally as well as ventrally, genital somite asymmetrical with smoothly curved left side and a toothlike process in distal half of right side. Viewed from left side, genital prominence with a rounded tubercle at its anterior base and its posterior side perpendicular to ventral wall of somite. Left genital flange relatively large, followed by a tubercle on genital prominence and another on ventral wall of somite. Cephalosomal appendages and swimming legs almost identical to those of E; concinna. Male: i, forehead (left side); j, exopod of left 5th leg (anterior); k, idem (mdial); l, distal end of serrated lamella (anterior).
