It seems to me that this is Noserius ocapamensis Lepesme and Breuning 1953 (= Hypoechrus ocapamensis). But I think Francesco will be able to confirm or deny .... Maybe even the name Noserius changed to Afronoserius? No?
Afronoserius ocapamensis (Lepesme, 1953) is a Western species (Sierra Leone, Ivory Coast). Actually, this specimen is a female of Afronoserius angolensis (Lepesme & Breuning, 1955)
