Taxonomic and distributional notes: Peters (1881) mentioned both “ Cuango ” and “Macange” [= Malanje] in the original description. Von Mechow collected along the Cuango River in Malanje Province, specifically near the Francisco José Waterfalls. Because the Cuango extends into other provinces and because there are also villages with this name, the origin of Peters’ type of Microsoma collare has sometimes been confused .
