A hydrobiological survey of scarce permanent aquatic environments in the Ennedi and Ounianga regions of northern Chad yielded a small collection of 7 odon. spp. It adds 3 new spp. to the known fauna of Chad: Ischnura senegalensis, Pseudagrion hamoni, and Orthetrum sabina. The presence of O. sabina at Ounianga represents the westernmost record of this oriental sp. in N. Africa. Another oriental element, O. taeniolatum, may not exist in Africa W. of the Nile, possibly being replaced there by the closely related O. kollmannspergeri Buchholz. The 44 spp. hitherto reported from the Republic of Chad likely represent only a third or less of those to be expected in the country.
