Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  regani: Named for C. Tate Regan whose pioneering work at the British Museum of National History laid the foundation for many studies of African freshwater fishes (Ref. 52346).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Tropical

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: lakes Upemba and Mweru, and from the rivers Lualaba, Lufira, Luvua and Luapula below Kasenga, in Democratic Republic of the Congo and Zambia (Ref. 52346).

Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 14-16; Anal spines: 3; Anal soft rays: 7 - 9; Vertebrae: 28 - 29. Diagnosis: 37-40 lateral line scales; terminal canal bearing scales of upper branch do not descend scale rows; 2 series of scales between upper lateral line and anterior part of lower; 15-17 gill-rakers along lower limb of first arch; entire premaxillary oral valve; 28 vertebrae; inferior vertebral apophysis of standard Tylochromis type; lower pharyngeal jaw never extremely robust with mill-like molariform teeth extending over dentigerous surface; 10-15 relatively stout outer row teeth and usually only one inner row on lower jaw (Ref. 52346).

Biology     Glossary (e.g. epibenthic)

Benthic macrophage (Ref. 52346). Mainly feeds on plants and insect larvae; maternal mouthbrooder that does not pair-bond (Ref. 52307).

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):  2.6   ±0.26 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
Price category (Ref. 80766):   Unknown.
