Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Eponymy: Professor Oskar Rudolph Neumann (1867–1946) was a German ornithologist who collected widely in east and northeast Africa (1892–1894). [...] (Ref. 128868), visit book page.

Issue
Somewhat mysterious species in that several undetermined Chiloglanis populations from East and Central as well as South Africa have been assigned to this species, although it is only inadequately known (Ref. 78218).
Environment: milieu / climate zone / rango de profundidad / distribution range
Ecología
; agua dulce bentopelágico; pH range: 6.0 - 7.5; dH range: ? - 15. Tropical; 20°C - 26°C (Ref. 2059); 10°S - 19°S
Africa: Limpopo River system, Cunene, Kafue, Zambezi (above and below Victoria Falls), Okavango, Lake Malawi and Lake Kariba (Ref. 3202, 52193). Presence in the upper Congo River basin in Zambia (Ref. 3202) is unconfirmed (Ref. 52193) and questionable. Also reported from the Pungwe and Buzi systems and east coast rivers in Tanzania (Ref. 7248, 52193). Several undetermined Chiloglanis populations from East and Central as well as South Africa have been assigned to this species, although it is only inadequately known; also Rufiji/Ruaha specimens are not conspecific (Ref. 78218).
