A new species, Dasyhelea pseudopollinosa Díaz & Ronderos sp. nov., is described from Brazil, illustrated and photographed as pupae and male and female adults. The male of D. paulistana Forattini & Rabello, 1957 is described for the 􀂿 rst time, and the pupa and female adult are redescribed. Pupae of both species were collected from mats of 􀃀 oating fern leaves (Salviniaceae and Azollaceae) in Brazil and Argentina, and exhibit a respiratory organ which is thick at the base and tapering to a sharp apex, and segment 9 with elongate, slender apicolateral process. Diffe rences between the two species are established, and they are also compared with Nearctic congeners that have the same kind of pupa: D. pollinosa Wirth, 1952, D. traverae Thomsen, 1935, and D. chani Wirth & Linley, 1990.
