Remarks. A subspecies known exclusively from D. R. of the Congo (Basilewsky 1949, Insectoid.info 2017). Our specimens fit very well the Basilewsky`description. Adults were found on ground during night near public lights (first locality) (see also C. rikatlensis remarks) and beneath litter on sandy whitish soil within an open secondary forest (second locality). It is a new species/subspecies record for Angola.
