          Abstract

          Three new species of Hydroptilidae are herein described and illustrated from specimens collected with light traps in the states of Pará and Rio de Janeiro, Brazil. Flintiella carajas sp. nov., from Floresta Nacional de Carajás, shares with F. panamensis Harris, Flint & Holzenthal, 2002, F. tamaulipasa Harris, Flint & Holzenthal, 2002, F. yanamona Harris, Flint & Holzenthal, 2002, and F. manauara Santos & Nessimian, 2009 a deeply incised phallic apex. However, males can be distinguished by a ventromesal process on segment VII, by lacking dorsal hooked processes on segment IX, by the elongate subgenital plate, and by the lateral lobes of the phallic apex slightly curved laterad. Rhyacopsyche diacantha sp. nov. is closely related to R. yatay Angrisano, 1989 and R. garuhape Angrisano & Sganga, 2009. All three species have complex inferior appendages with ventral and dorsal lobes. The new species is distinguished by the male genitalia with segment X two times longer than broad, inferior appendages with the apices obliquely truncate, and a bilobed dorsal lobe on the inferior appendages. Features of the male genitalia of Rhyacopsyche angra sp. nov., R. hagenii and R. dikrosa are similar, but the first species can be distinguished by the inferior appendages truncate apically and produced laterad, and a phallus with the internal tubule hooked subapically and apically.
