This fish looks for all the world like Aphy. elegans because of the barring on the flanks, but the ice blue in the caudal and dorsal fins says it's cognatum. It was collected in April 2014 by Serge Mevellec in the Punda river, near the town of Kinsuka in the Kinshasa region of the Democratic Republic of Congo. In 2017 Russel Tate found the same fish in a small creek in the Momboyo drainage in Central Congo.
