Ozolaimus Dujardin, 1845 (= Macracis Gedoelst, 1916), a little known nematode genus from the cæcum of Iguana tuberculata

Abstract

Rudolphi (1819) first described a nematode from the intestine of Iguana tuberculata under the title, Ascaris megatyphlon. Since then considerable progress has been made in our knowledge of the parasitic Nematodes and most of the forms described by Rudolphi under Ascaris have been placed in new genera. Dujardin (1845) re-examined these forms and created a new genus, Ozolaimus, for Ascaris megatyphlon and removed certain other forms to the genus Oxyuris. He differentiated the two genera of Oxyuris and Ozolaimus by the presence of two simple lips in Ozolaimus and three simple or lobed lips in Oxyuris.
