Two species are cited for the first time for Argentina, D. adscendens and D. distortum, and two synonyms are proposed, D.
longiarticulatum, under D. bridgesii, and D. dutrae, under D. polygaloides. The geographic distribution of each species and some ecological characteristics are also given. The first record of the chromosome count of D. hassleri, 2n = 22 is presented.
