Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); labrodon: Named by Regan (1920) presumably in reference to the formidable pharyngeal tooth development of this species; derived from the Greek labros = fierce, greedy and odontos = tooth (Ref. 52346).
More on author: Regan.

背面の脊椎 (合計) : 14 - 16; 背鰭 (合計) : 13 - 15; 肛門の骨: 3; 臀鰭: 7; 脊つい: 28. Diagnosis: lateral line with 34 or fewer scales; 17-18 gill-rakers along lower limb of first arch; inferior vertebral apophysis with characteristic spade-like outline; extremely robust lower pharyngeal jaw with flattened mill-like molariform teeth covering 2/3 of the dentigerous surface; fully ossified posttemporal latero-sensory canal; relatively short pectoral fins rarely reaching the level of the vent (Ref. 52346).
Benthic macrophage (Ref. 52346). Feeds on insects and their larvae, as well as on molluscs, plants and detritus; maternal mouthbrooder that does not pair bond (Ref. 52307).
