Remarks, on six species of Heterakid Nematodes parasites of brazilian Tinamid birds with description of a new species

Nematodes representing five species of the genus Heterakis, namely: H. inglisi n. sp., H. alata, H. gallinarum, H. spiculatus and one species of the genus Odontoterakis, O. multidentata, were studied. Heterakis inglisi n. sp. closely resembles H. spiculatus, differing from it by smaller size of spicules, precloacal sucker and terminal spike of the tail in the males. Heterakis arquata and H. brasiliana are only listed, for they were not found during the present study. Odontoterakis multidentata is reported in Brazil for the first time. New host records are estabilished for most of the species. These species are fully illustrated

Nematode parasites of Brazilian psittacid birds, with emphasis on the genus Pelecitus railliet & Henry, 1910

In the present paper, some species of nematodes from Brazilian parrots are studied: Aproctapyrrhurae. Ascaridia hermaphrodita, A. sergiomeirai, Pelecitus circularis and P. helicinus. Single female specimens of Pelecitus sp. and Thelazia sp. are presented. The male of P. circularis is fully illustrated, for the first time, since 1884. Ascaridia sergiomeirai is also restudied 59 years after proposition. New host records are estabilished. Remarks on other species of nematodes occuring in psittacid birds are included
