HABITAT. — Oedaleus senegalensis lives in dry areas (H. Tlili, pers. obs.).

REMARKS. — Chopard (1943) mentioned that Oedalus senegalensis is reported in Gafsa by Krauss (1877), but this citation is not correct, because Krauss (1877) made his study in Senegal. The true citation of this species in Gafsa is found in Vosseler (1902a). Later, in his revision of the genus Oedaleus, Ritchie (1983) did not mention this species in Tunisia. Therefore we confirmed here the presence of O. senegalensis in south-west of Tunisia.
