Tropicranus albocristatus cassini (Finsch, 1903) – from Nigeria east to Uganda and south to Angola.
Tropicranus albocristatus macrourus (Bonaparte, 1850) – Ivory Coast and Ghana.

It is frequent in parts of its range. Although its population is difficult to estimate, it is not thought to be threatened.^[1]
