Alphasida (Glabrasida) bounaceurensis sp. nov. is described from the Jbel Bou Naceur top, the most eastern summit of the Moroccan Middle Atlas range. It is compared to other morphologically and geographically related species. Type material of Alphasida (Glabrasida) lecerfi Koch, 1940 and its subspecies is studied. A lectotype is designated for Alphasida (Glabrasida) iblanensis Antoine, 1939. We propose here a new synonymy: Alphasida (Glabrasida) iblanensis Antoine, 1939 = Alphasida (Glabrasida) lecerfi ighrezranensis Koch, 1940.
