Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); robertsi: Named for Tyson R. Roberts whose knowledge of the African waterways and their ichthyofauna has been of great value to many studies of the freshwater fishes of Africa (Ref. 52346).
Eponymy: Dr Tyson Royal Roberts (d: 1940) is an American naturalist and evolutionary biologist who has devoted most of his life to studying biodiversity, particularly that of fishes, throughout the tropics. [...] (Ref. 128868), visit book page.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 14 - 16; Rückenflossenweichstrahlen (insgesamt) : 12 - 15; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 8; Wirbelzahl: 28 - 29. Diagnosis: upper lateral line extending full length of dorsal fin base and descending a row before proceeding length of three or more scales; 14-15 gill-rakers, widely spaced along lower limb of first arch; 36-40 lateral line scales; head length 29.0-35.7% of standard length; usually 29 vertebrae; inferior vertebral apophysis short and oriented caudad rather than of standard Tylochromis type (Ref. 52346).
Opportunistic benthic macrophage (Ref. 52346). Mainly feeds on plants and insects (as well as their larvae) (Ref. 52307). Female mouthbrooder (Ref. 52307, 52346) that does not pair-bond (Ref. 52307).
