New data on someRhithrogenaspecies from Lebanon, Israel and Iran are provided. The nymph and egg ofRh. znojkoi(Tshernova, 1938) are described for the first time. A new species,Rh. paulinaesp.n., is described from the imaginai, nymph and egg stages, and its affinities are quoted. The systematic status ofEpeironDemoulin, 1964 is also discussed. On the basis of our material, as well as of the literature, evidence for the synonymy withRhithrogenaEaton, 1881 is presented.
