Not one species was mentioned in LucAs's (1846) The genera Agroeca, Agraeci11a , Apos1e1111s and Scoti11a occurring in standard work on the fa una of Algeri a. Only in 1932, the Maghrcb countries are revi sed. Eight species are recorded, four of wh ich arc new , the other four are re-described: Agroeca a1111ulipes SIMON menti oned the presence of Agroeca annulipes SIMON, Agroeca inopina O.P.-Cambridge, Agroeca 111aghrebe11 sis 11.
