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).
Eponymy: Professor Dr Dirk Frans Elisabeth Thys van den Audenerde (d: 1934) is a Belgian ichthyologist and Museum Director. [...] Emil Woolf Kentridge-Young is the grandson of South African artist and animator of c. [...] (Ref. 128868), visit book page.

وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 15 - 17; الأشعة الظهرية الناعمة (المجموع) : 9 - 11; شوكة شرجية: 3; أشعه شرجية لينه: 7 - 9; فقرات: 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).
