(1929, Bull. Soc. Ent. Belg., 69: 138, worker, queen; type locality La Caille, Algeria and Ain Draham, Tunisia) is a new synonym of P. numidicum Santschi (1912, Bull. Soc. Hist. Nat. Afr. Nord, 4: 172 - 173, figs. 1, 2, worker, queen; type locality Ain Draham, Tunisia).
In the Santschi Collection, Naturhistorisches Museum, Basel, the types of P. numidicum are callow in part, but I could find no other differences between them and the types of P. normandi in the same collection.
