Three new species of Demidospermus Suriano, 1983 were found in mixed infections on the gills of 4 pimelodid catfish collected in the Amazon River basin around Iquitos, Peru. Demidospermus peruvianus n. sp. (type host, Pimelodus sp.) is characterized by the presence of the male copulatory organ with 2 lateral, thickened projections, and the vagina with a loop at its middle. Demidospermus curvovaginatus n. sp. from P. ornatus, Pimelodus sp. (type host), and Pimelodidae gen. sp. differs from its congeners by the presence of a funnel-shaped vagina directed posteriorly and a male copulatory organ with a small lateral projection at its base. Demidospermus striatus n. sp. from P. blochii and Pimelodus sp. (type host) is distinguished by a cup-shaped vagina with conspicuous ridges at the perimeter of the aperture with a short tube directed anteriorly. In addition, Urocleidoides lebedevi Kritsky and Thatcher, 1976, is transferred to Demidospermus.
