This species is distinguished by the following characters: pectoral-fin rays 20-28; lateral-line pores 124-186 ((vs. 32-38 and 88-101, respectively, in E. electricus); narrow head (vs. wide in E. voltai); the distance between medial margins of contralateral dentaries at transverse through last two ventral pores is 2-3 times shorter than E. voltai; deep skull, cleithrum lies between vertebrae 1 and 2 (vs. depressed with cleithrum lying between vertebrae 5 and 6, in E. electricus and E. voltai). Low-voltage electric organ discharges or EOD duration 1.24-1.78 ms, high-voltage EOD 151 V (20.0 cm TL) to 572 V (60.9 cm TL) (Ref. 120918).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
ຊັ້ນເຂດຮ້ອນ (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
ຄວາມຢືດຢຸ່ນ (Ref. 120179):  ຕຳ່ຫຼາຍ, ປະຊາກອນຕຳ່ສຸດທີ່ໃຊ້ເວລາສອງເທົ່າຫຼາຍກວ່າ 14 ປີ (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (89 of 100).
