Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); mylodon: Named by Regan (1920) presumably in reference to the mill-like molariform pharyngeal dentition of this species (Ref. 52346).

Épines dorsales (Total) : 13 - 14; Rayons mous dorsaux (Total) : 14 - 15; Épines anales: 3; Rayons mous anaux: 7 - 8; Vertèbres: 28. Diagnosis: lateral line count of 38-43 scales; 16-17 closely packed gill-rakers along lower limb of first arch; extremely robust lower pharyngeal jaw with mill-like molariform teeth occupying at least 2/3 of dentigerous surface; third pore of mandibular laterosensory canal enlarged compared to size of preceding pores (Ref. 52346).
Benthic macrophage (Ref. 52346). Feeds mainly on insects and their larvae, but also (in small quantities) on crustaceans and molluscs (Ref. 52307). Maternal mouthbrooder (Ref. 52307, 52346) that does not pair bond (Ref. 52307). Marked intolerance to oxygen lack (Ref. 246).
