Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); microdon: Named by Regan (1920) presumably in reference to the fine pharyngeal dentition of the species (Ref. 52346).
More on author: Regan.

Épines dorsales (Total) : 14 - 15; Rayons mous dorsaux (Total) : 12 - 15; Rayons mous anaux: 7; Vertèbres: 28 - 29. Diagnosis: marked hypertrophy of lateral line canals on flank and caudal fin; inflated preopercular laterosensory canals; distinctive excavation of premaxillary oral valve (Ref. 52346).
Restricted in its distribution to the lake proper and absent from the surrounding swamps and inundated forest (Ref. 52346). Predominantly a lacustrine form (unusual among Tylochromines)(Ref. 52346). Benthic microphage (Ref. 52346). Feeds mainly upon small organic particles, plants and invertebrates; maternal mouthbrooder that does not pair bond (Ref. 52307).
