Surface topography of Erilepturus hamati Manter, 1947 (Digenea, Family: Hemiuridae) by scanning electron microscopy.
The tegumental ultrastructure of adult Erilepturus hamati was studied by scanning electron microscopy (SEM). Adult worms were recovered from intestine of Red Sea fishes, Pherapon jarbua and Lethrinus mahsena collected at Hurghada, Red Sea, governorate. The study revealed the presence of three types of sensory papillae: type I button papillae around suckers, type II ciliated dome papillae scattered on tegumental surface of soma and type III domed papillae distributed on tegument of posterior extremity of soma. High magnification of tegumental surface of the pit in which the ecsoma is retracted showed that it has a number of small dermal outgrowths. Many pores are scattered on the tegumental surface. The tegumental ultrastructure of the present genus was compared with those of other genera of trematodes, previously described from the Red Sea fishes.
