ABSTRACT
Specimens collected from the large intestine of the side-necked turtle Podocnemis unifilis Troschel, 1848, in the region of Cumina and Trombetas rivers near Para, Brazil are assigned to a new genus and Paraorientatracti semiannulata. The new genus is separated from the nearest genus Orientatractis by the funnel-shaped mouth opening, the presence of 4 distinct lips, 4 papillae in the internal cycle, one on each lip margin, 2 lateral amphids with large amphidial pores and absence of submedian papillae. It is also separated from Orientatractis and Proatractis by the presence of striated lateral alae which curve dorsally extending from mid oesophagus to mid tail, the difference in size of the vulvar opening and the presence of large transverse ridges or semiannules on the dorsal surface. The new species can be separated from the species of the genera Orientatractis and Proatractis by the characters that distinguish the genera and the arrangement of the caudal papillae on the male. A host/parasite list for Podocnemis spp. is included.
