Justification
Chiloglanis angolensis has only been found in the stream crossing Chibia-Jau road, at Jau-Onguéria bifurcation, a few km south of Chibia, near Sá da Bandeira, Angola (type locality) (Eschemeyer 1997) and in the Kwango River (Cuango River) at Cafunfo, Central Congo River basin, Angola (Poll 1967). The species may be more widespread than is currently known. More information is needed on the species distribution before an assessment can be made, and it is therefore categorized as Data Deficient.
