Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  sudanensis: Named by Daget (1954) presumably in reference to the middle Niger localities he sampled in the French Sudan; the French term "soudanienne" (Soudan) is anglicized by Beadle (1974) and Lowe-McConnell (1975, 1985) as "soudanian" (Ref. 52346).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  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):  2.6   ±0.25 se; Based on food items.
Widerstandsfähigkeit (Ref. 69278):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
