“…Several studies have related this family with the superfamily Paramphistomoidea (La Rue 1957, Holliman 1961. Jousson and Bartoli (1999) supported the inclusion of Mesometridae in Paramphistomiformes, as proposed by Brooks et al (1985), and its close relationship to the Microscaphidiidae.…”

The spermiogenesis process in Wardula capitellata begins with the formation of a differentiation zone containing two centrioles associated with striated rootlets and an intercentriolar body. Each centriole develops into a free flagellum orthogonal to a median cytoplasmic process. Later these flagella rotate and become parallel to the median cytoplasmic process, which already exhibits two electron-dense areas and spinelike bodies before its proximodistal fusion with the flagella. The final stage of the spermiogenesis is characterized by the constriction of the ring of arched membranes, giving rise to the young spermatozoon, which detaches from the residual cytoplasm. The mature spermatozoon of W. capitellata presents most of the classical characters reported in digenean spermatozoa such as two axonemes of different lengths of the 9 + "1" trepaxonematan pattern, nucleus, mitochondrion, two bundles of parallel cortical microtubules and granules of glycogen. However, some peculiarities such as two lateral expansions accompanied by external ornamentation of the plasma membrane and spinelike bodies characterize the mature sperm. Moreover, a new spermatological character is described for the first time, the so-called cytoplasmic ornamented buttons.

“…The fact that sheepshead are swimming vertebrates may also benefit C. occidentalis in terms of dis I am in agreement with the statements of Stunkard (1963) and LaRue (1957) Brinkmann (1957) , and Burt (1968) on Taeniocotyle elegans as well as those by Odhner (1910) on Stichocotyle nephropsis have revealed that juvenile as well as adult parasites of both species occur in a very specific location (the bile ducts) in their vertebrate hosts;…”

“…Because digenean trematodes, with rare exceptions, begin their development in molluscs, they have been considered primitively parasites of molluscs by Chandler (1923), Stunkard (1946 , LaRue (1957) , andWright (1960) . Among those aspido bothrians whose life cycles are known, development begins in a mollusc as in the Digenea.…”

“…Manter (19 31, 1947Manter (19 31, , 1954 treated the aspidobothrians as a family of the Digenea. LaRue (1957) , however, concluded that aspidobothrians could not be considered together with the Digenea and should be regarded as a separate group, the Aspidogastrea. Stunkard (1963) , in an excellent review re garding the status of the Aspidobothria, concluded that by definition the latter are basically monogenean but are related to the Digenea, and assigned them to the order Aspidobothrea under subclass Malacobothria.…”

“…Extensive studies have been conducted on marine cercariae from the Northumberland and Scottish coasts (Lebour, 1911), the Gulf of Naples (PaIombi, 1940), the Gulf of Mexico (Holliman, 1961), the Caribbean (Cable, 1956;1963) and on freshwater cercariae from India (Sewell, 1922), North America (Cort, 1915) and South Wales (Probert, 1966;Pike, 1968). Knowledge of larval stages and their development have been useful in revising the systematics of digenetic trematodes (La Rue, 1957). Studies on larval Digenea fauna have also contributed to a better understanding of the ecological relationships among organisms in aquatic environments.…”
