Based on the spider collection of the Muséum national d’Histoire naturelle, Paris, the data on the poorly known Algerian representatives of Nemesia Audouin, 1826 are renewed. Twelve species of Nemesia were recognized among the studied material. The following six new species are described: N. algerina n. sp. (♂♀), N. almoravida n. sp. (♂♀), N. annaba n. sp. (♂♀), N. decaei n. sp. (♂♀), N. dido n. sp. (♀) and N. tanit n. sp. (♀). Nemesia dorthesi Thorell, 1875 is recorded within Algeria for the first time. Nemesia ?macrocephala Ausserer, 1871 and N. ?meridionalis (Costa, 1835) are assumedly occurred in the country. One further unidentified species is figured and listed as Nemesia sp. Unknown hitherto males of N. africana (C.L. Koch, 1838) and N. didieri Simon, 1892, are described for the first time and their females are redescribed. Lectotypes are designated for Nemesia didieri Simon, 1892 and Nemesia ariasi Simon, 1914. Additional data on the somatic and copulatory structures and distribution of all the studied species are provided.
