| Diagnosis |
This species is distinguished morphologically from its congener E. newberryi, by the following characters: reduction (for over ca. 2.5 cm SL) of the anterior supraorbital canal and concomitant increase in number of exposed neuromasts, 8-12 in adults (vs. 5-8 in E. newberryi); fewer pectoral fin ray 18-19 (vs. 19-21) and branched caudal rays 10-11 (9-12) [vs. 12-13 (11-14)] due to reduction in this count on the lower half of the caudal fin (Ref. 110200). |
