Short Description
Diagnosis after Ng & Lin, 2026 [36209]: A presumably moderate-sized species of the E. pusillus group, differing from all the congeners in having a combination of dermal denticles arranged in well-defined rows, dorsal fins naked, the origin of flank marking anterior to a vertical through D2 origin; the flank-marking base anterior to a vertical through D2 insertion, tip of caudal-fin base marking barely extending beyond the lower origin of caudal-fin, and extremely long central caudal marking.

Dentition
Teeth dissimilar in upper and lower jaw (Fig. 12); upper teeth multicuspid, in three functional series, small, central cusp thick, with one to two cusplets on each side; inner pair of cusplet longest, length about one-third of the central cusp; teeth in lower jaw unicuspid, in three series, one functional; lower-teeth blade-like, with strongly oblique cusp. Tooth count of upper jaw 22, lower jaw 28, total count 50. [36209]
