Etymology: Heteromormyrus: Greek, heteros = other + Greek mormyros = a kind of fish similar to Boops sp. (Ref. 45335); szaboi: Named in honor of the late Dr. Thomas Szabo of the Laboratoire de Neurophysiologie Sensorielle Comparée (CNRS) at Gif-sur-Yvette near Paris, one of the founding fathers of the field of electroreception (Ref. 52128).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00612 - 0.02839), b=2.85 (2.67 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
