Etymology: Tyrannochromis: Greek, tyranos = despotic + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Quote Snoeks and Hanssens, 2004 (Ref. 55954): "We tentatively accept the synonymy of T. polyodon (Trewavas, 1935) and T. maculiceps (Ahl, 1927) with [the] species (T. macrostoma (Regan, 1922)) as suggested by Konings (1996). [But] A definite conclusion cannot be given, as we have not examined the types of these nominal species."

Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.73 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
