Aspectos morfológicos de Paradeletrocephalus minor (Molin, 1861) Freitas & Lent, 1947, en andu (Rhea americana), por medio de miscroscopio de luz y microscopio electrónico de barrido MORPHOLOGYC ASPECTS OF Paradeletrocephalus minor (MOLIN, 1861) FREITAS & LENT, 1947. IN ANDU (Rhea americana), BY LIGHT MICROSCOPE AND SEM

The aim of this study was to report some external morphological features of Paradeletrocephalus minor MOLIN (1861); FREITAS & LENT (1947). The parasites were collected during necropsy from the small intestine and large intestine of andú (Rhea americana), hunted in its native environment near Tandil City, Buenos Aires Province, Argentina. Collected specimens of Paradeletrocephalus minor were observed by light microscopy in order to be classified. Later the parasites were put into a 3% glutaraldehyde solution, dehydrated, dried by critical point, assembled, metalized, observed and photographed with a SEM. This is the first description of some external morphologic features of this species carried out by Light microscope and SEM in Argentina
