Diagnosis: conspicuous discrete dark spot present on upper pectoral fin base (if specimen is very dark spot may not be highly contrasted but is still distinct; sensory papillae on upper rear field of opercle form a single arching row; 54-63 scales in longitudinal series, usually 56 or more (Ref. 81660).Description: 39-55 predorsal scales (usually 39-47); posterior half of cheeks usually with small cycloid scales; opercle usually entirely scaled; 54-63 longitudinal scales (usually 56-60); 16-22 (usually more than 18) transverse scale rows (Ref. 81660).Coloration: distinct spot on upper pectoral fin base; spotting on flanks irregular, less uniform and with larger spots than in E. daganensis; dorsum may be dark with 4-5 saddle-like bands, not extending below mid-line; some individuals with a spot on lower pectoral fin base; 1st dorsal fin with two dark horizontal bands separated by translucent band; 2nd dorsal fin with 4-5 longitudinal rows of spots; anal fin with rows of spots; some specimens dark with dusky pectoral and pelvic fins, median fins with banded pattern; caudal fin dusky with indistinct vertical bands of spots; abdomen generally tan (Ref. 81660).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Analsoft rays: 8
