Resumo

Purpose To describe three new species ofCosmetocleithrumin the gills ofTrachelyopterus galeatus(Siluriformes, Auchenipteridae) from Aguapei River, Upper Parana River basin, Sao Paulo State, Brazil. Methods Fifty-three specimens ofT. galeatuswere captured in the mouth of the Aguapei River from August 2013 to June 2014. Monogeneans were mounted unstained in Hoyer's and Gray and Wess's medium. Results Cosmetocleithrum spathulatumsp. n.,Cosmetocleithrum baculumsp. n., andCosmetocleithrum galeatumsp. n. differ from all known congeneric species mainly in the morphology of the accessory piece (i.e. spatulate-shaped, claviform, and a straight rod with hook-shaped distal portion, respectively). Also, the three new species share hooks with different sizes with hooks pairs 5 and 7 bigger than others and with an erect delicate point, inconspicuous thumb, longer shaft, and slender shank. Conclusions To date, 18 species ofCosmetocleithrumwere recognised parasitizing siluriforms in the Neotropical region. The present study expands the number to 21 species, however, despite this increase, the number of knowntaxaof monogeneans in neotropics is far from representing the ideal situation. (AU)
