Description
Summary:The objective of this study is to present a description of a new species of Sphincteristomum Oshmarin, Mamaev & Parukhin 1961, named Sphincteristomum mediterraneae, which is described in Oran bay, Algeria. It parasitizes the intestine of naturally infected Pagellus erythrinus, Teleostei, Sparidae. The Pagellus erythrinus is an important food fish in the Mediterranean. This genus belongs to the family Apocreadiidae, sub family Schistorchiinae, characterized by an obvious oral muscular sphincter, into a large oral sucker, a disc-shaped acetabulum under the intestinal bifurcation, an ocular pigment scattered in the forebody, a sequence ovary and two testes in tandem, and an I-shaped excretory bladder. In the new species, the digestive apparatus displays a hexagonal peculiar aperture, followed by a longitudinal slit, a waved pharynx, two long and broad caeca, with a thick internal wall of endothelial cells. In the same P. eryrthrinus, immature worms devoid of genitalia, young worms with genitalia devoid of eggs and ovigerous worms, live together with senile specimens.
