Etymology: Benthochromis: Greek, benthos = depth of the sea + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Eponymy: M (probably Monsieur) Tricot, Director of the Great Lakes Railroad Company (Albertville), was honoured for his interest in and concern for the Belgian Hydrobiological Mission to Lake Tanganyika (1946–1947), during which the type was collected. (Ref. 128868), visit book page.
