A fruit collected at Tundo Quilombo in Pungo Andongo, by Welwitsch (fruit 
729), probably belongs to D. psilopus. Welwitsch also states in a note that 
this species occursin Pungo Andongo as well as in Cazengo. Ficalho records it from 
the River Ninda, Central Angola, where Serpa Pinto collected it.
