Light and Electron microscopic Studies of Parapharyngodon sceleratus and Physaloptera sp. Discovered in Some Reptiles of Qena Governorate, Egypt

The present study is the first that has been carried out on redescription of helminth parasites infecting reptiles in Qena Governorate. Light microscope, scanning electro microscope and Camera Lucida were used. During the present study about 106 individuals of Chalcides ocellatus (eye shrink or Sehliadoffana) and 24 individuals Psammophis sibilans (a snake) were collected from Qena Governorate. Two nematode species were collected and identified. Parpharyngodon sceleratus (Physalopteridae, Travassos, 1919) and Physaloptera sp. (family: Physalopteridae, Leiper 1908). The first and the second species were collected from the larg intestine of Chalcides ocellatus and stomach of Psammophis sibilans, respectively.
