Etymology: Thysochromis: Greek, thysis, -eos = impulsive + Greek, chromis = a fish, perhaps a perch (Ref. 45335); emili: The species is named for Emil Woolf Kentridge-Young, grandson of William Kentridge and Anne Stanwix, in recognition of their support of research in Africa (Ref. 122428).

Short description
Morfología | Morfometría
Espinas dorsales (total): 15 - 17; Radios blandos dorsales (total): 9-11; Espinas anales 3; Radios blandos anales: 7 - 9; Vértebra: 24 - 26. Diagnosis: Thysochromis emili is distinguished from its West African congener, T. ansorgii, by the following combination of characters: fewer scale rows between the pectoral and pelvic-fin origins, 3-4 vs. 5-6; jaw teeth closely spaced and evenly implanted over entire length of both upper and lower jaws vs. widely spaced and unevenly implanted along distal portions; a supraoccipital crest that is continuous with the frontal ridge vs. terminating posterior to frontal ridge (Ref. 122428); a shorter postorbital length, 38.2-41.9% of head length vs. 42.8-46.7%; and a shorter caudal peduncle length, 7.7-11.3% of standard length vs. 11.4-12.7% (Ref. 122428).
Found in well oxygenated lakes and rivers situated in higher order systems of the Kouilou and Noumbi River basins (Ref. 122428). It occurs over sandy substrate in shallow, less than 0.5 m deep, clear, shoreline waters fringed by abundant overhanging vegetation, deeply undercut banks and root wads (Ref. 122428). It is probably a pair-bonding, cave brooder (Ref. 122428).
