Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); trewavasae: Named for Dr. Ethelwynn Trewavas who has so generously shared her knowledge of the African Cichlidae with colleagues and students, and who originally brought the unusual Tylochromis specimen to the authors attention (Ref. 52346).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 3.2 ±0.47 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
