A new species of the cleptoparasitic bee genus Chiasmognathus Engel, 2006 is described and figured from southwestern Niger. Chiasmognathus saheliensis sp. nov. (Ammobatini) is distinguished from its congeners by the combination of its coloration, integumental sculpturing (particularly that of the mesosoma), and genitalic structure. Species of the genus victimize nests of Nomioides Schenck, 1867 and perhaps Ceylalictus Strand, 1913 (Halictidae: Halictinae: Nomioidini), both of which are known to occur in Niger.
