“…Finally, from a developmental aspect, it appears that W. virilis "…exhibits less of a tendency toward progenesis than of any other caryophyllid", according to Ibraheem and Mackiewicz (2006: 56). Because of these pronounced morphological differences, Hunter (1927) relegated Wenyonia to its own subfamily (= family). Moreover, the recent cladistic analysis of the phylogenetic relationships of the monozoic tapeworms found that Wenyonia and Hunterella Mackiewicz et McCrae, 1962 did not form a monophyletic group with other caryophyllaeids but formed a sister group with gyrocotylideans, one of the out groups (Oros et al 2008).…”

The ultrastructure of spermiogenesis in Wenyonia virilis Woodland, 1923, a caryophyllaeid cestode from the silurid Nile fish Synodontis schall (Bloch et Schneider, 1801), is described by means of transmission electron microscopy (TEM) for the first time. Spermiogenesis follows the characteristic caryophyllidean type and is initiated by the formation of a differentiation zone. This area, delimited at its base by a ring of arching membranes and bordered by cortical microtubules, contains two centrioles associated with typical striated rootlets with a reduced intercentriolar body between them. The apical area of the differentiation zone exhibits electron-dense material that is present only during the early stages of spermiogenesis. Only one of the centrioles develops into a free flagellum that grows at an angle of >90° in relation to the cytoplasmic extension. Spermiogenesis is also characterized by a flagellar rotation and a proximodistal fusion of the flagellum with the cytoplasmic extension. The most interesting features observed in W. virilis are the presence of a reduced, very narrow intercentriolar body and the unique type of flagellar rotation >90°. Results are compared with those described in two caryophyllideans, Glaridacris catostomi Cooper, 1920 and Khawia armeniaca (Cholodkovski, 1915). Contrary to the original report of OEwiderski and Mackiewicz (2002), that flagellar rotation has never been observed in spermiogenesis of G. catostomi, re-assessment of their description and illustrations leads us to conclude that flagellar rotation must logically occur in that species. The value of various morphological features of sperm in phylogenetic inference is discussed.

“…The same species was recorded by Mehra (1930) from Clarias magus in India and Ramdevi (1973) from Clarias batrachus in India. Hunter (1927) placed the genus in sub-family of his own namely. Lytocestinae and retained only three species L. adhaerens.…”

Nine specimens of the cestode parasites were recovered from the intestine of Clarias batrachus at Amravati, in the month of March, 1984. They were stained in Borax carmine, whole mount and histological slides of the worm were prepared for detail studies. The mature flattened specimens were long, cylindrical and measure 4.805 in length and 0.674-1.484 in breadth. Morphology and anatomy of the worm is fully discussed in this paper. Keywords:Fish parasite infection, Helminthes, New Tapeworm Lytocestus alii n.sp. Morphology, Anatomy, Clarias batrachus, Amravati, India IntroductionThe genus Lytocestus was introduced by Cohn (1908), with its type species L. adhaerens found in Clarias fuscus in Hong Kong. This genus was first confirmed by Woodland (1926), who included four more species, in addition to the type species, they are L. filiformis Woodland (1923) DescriptionNine specimens of the cestode parasites were recovered from the intestine of Clarias batrachus Bleeker, 1862, at Amravati, in the month of March, 1984. They were stained in Borax carmine, the whole mounts and histological slides were prepared for anatomical studies. The mature flattened specimens are long, cylindrical and measure 4.805 in length and 0.674-1.484 in breadth. The head is anterior and is bluntly oval remarkably narrower than the body, the testes are numerous,580-590 in number, preovarian, scattered in the central medullary region of the worm arranged 9-11 rows, in a single field, evenly distributed, oval in shape and measure 0.053/0.022 to 0.121/0.083 in length and breadth ( Fig.1.A,B

“…These edible fish are known to harbour a number of cestode parasites. Capingentidae (Hunter, 1930) is a small group of unsegmented cestodes, mainly parasitic in economically important fish, sometimes causing severe damage with 28 genera and 99 species described in Indian sub-continent (Pandey, et. al., 2010).…”

Abstract: Fresh water edible fish, Channa punctatus (Bloch) were examined for the study of piscine cestodes and few cestodes we obtained from the intestine of host.Morphological studies of the worm revealed that it is the new record in the genus Mystoides (Mathur,et al 2014) of the family Capingentidae (Hunter, 1930) order Caryophyllidea (Benden1893) and regarded as new species Mystoides chhaviensis.
