Abstract

During a survey of helminth parasites of bird Bubulcus ibis (Cattle egret) of Naushro Feroze District, Sindh Pakistan. More than 150 specimens were recovered from the small intestine of 10 hosts. Present specimens are closer to the type species Cotylurus cornutus (Rudolphi, 1808; Szidat, 1928) in specific characters such as general body shape including fore body and hind body, position and shape of suckers, position of tri-bocytic organ, position of gonads and arrangement of vitelline follicles.

Keywords

Cotylurus cornutus, Bubulcus ibis, Nausharo Feroze, Sindh, Pakistan.

Conclusion

In all essential features, present specimens appear to match the reported species in having general body structures, position of oral and ventral suckers, position of gonads, position of tribocytic organ but variations are noted in some species, general body shapes and sizes, position, sizes of oral and ventral suckers, size and shapes of gonads. Species identification is attempted at present and re-described as C. cornutus (Rudolphi, 1808) Szidat, 1928, Bhutta and Khan, 1975 with new host Bubulcus ibis and new locality Nausharo Feroze, Sindh, Pakistan

The genus Cotylurus is cosmopolitan and was created by (Szidat, 1928) as synonym of Cotylurostrigea (Sudarikov, 1961). The genus belongs to the family Strigeidae (Railliet, 1919) and subfamily Strigeinae (Railliet, 1919). (Yamaguti, 1971) reported 22 species of the genus Cotylurus type species as Cotylurus cornutus (Rudolphi, 1808; Szidat, 1928). Species reported from the India are C. orientalis (Vidyarth, 1937) from Anas creccaand C. intermedicus (Gupta et Gupta, 1962) from Hydrophasianus chirurgus. Species reported from Pakistan are C. cornutus (Rudolphi, 1808; Szidat, 1928; Bhutta and Khan, 1975) from Circus aeruginosus; C. sindhense (Birmani et al., 2009) from Fulicaatra and C. fuscicollisi (Sanjota et al., 2012) from Phalacrocorax fuscicollis. However, the present study represents a first record and new locality of the genus Cotylurus from Bubulcus ibis (Cattle egret) from Naushro Feroze, Sindh, Pakistan.
