Known solely from the type location in Zaïre. Wheeler (1922) giving the first description of akengensis, noted that it had a "dark brown paper nest", perhaps abandoned by some other species; he noted having a single dealated female from Liberia in his collection which probably belonged to the subspecies. Santschi (1935) also noted a specimen from Kasai, Ngombe, by Dr Schouteden, 9.xi.1921.
