Abstract
A new subspecies of Blaps nitens Laporte de Castelnau, 1840, however well-known but badly interpreted since more than one century, is described from Morocco: Blaps nitens medvedevi subsp. n. The origin of this confusion is explained in a chronological way. Consequently, a new synonymy is given: Blaps nitens subsp. barbara Solier, 1848 = Blaps substriata Solier, 1848 syn. n.
