[This specimen is the type of Spatha kamerunensis Walker, 1910.]

Aspatharia rugifera is found in the rivers of southern Cameroon, Gabon, and the Congo Basin; Aspatharia is typically a West African genus with only a few eastern species. Until recently, many taxonomists included what is now considered to be the genus Chambardia (= Spathopsis) as a subgenus of Aspatharia.
