Remarks

Braun (1899) erected the genus Phyllodistomum for Distomum folium Olfers, 1816 from the urinary bladder of fishes. Several species of the genus Phyllodistomum have been described so far from freshwater fishes of India; these are P. spatulaeforme Odhner, 1902 in Amphipnous cuchia from Muzaffarnagar; P. lewisi Srivastava, 1938 in Belone strongylura; P. macronium (Dayal, 1938) Yamaguti, 1958 in Macrones tengara; P. callichrius (Dayal, 1942) in Callichrous pubda from Lucknow; P. vachius Dayal, 1949 in Eutropichthys vacha; P. loossi Kaw, 1950 in Schizothorax esocinus from Kashmir; P. singhiai Gupta, 1951 in Mastacembelus armatus, Belone cancila and Ophiocephalus marulius from Lucknow; P. vittatusi Gupta, 1955 in Macrones vittatus from Assam; P. parorchium Jaiswal, 1957 in Glossogobius giuris from Hyderabad; P. indianum Jaiswal, 1957 in Heteropneustes fossilis from Hyderabad; P. chauhani Motwani and Srivastava, 1961 in Mystus aor and M. seenghala from Allahabad; P. tripathi Motwani and Srivastava, 1961 in Bagarius yarrelli and Pseudotripius and P. srivastavi Rai, 1964 in Heteropneustes fossilis and Mystus cavasius; P. cameroni Agarwal, 1966 in Rita rita from Lucknow.
Based on the presence of tapered forebody, broad foliate hindbody with crenulated margin and uterus occupying most space in the hindbody, the present specimens belong to the genus  Phyllodistomum. However, for lack of sufficient number of specimens, it could not be identified upto the species level. This is the first report of the occurrence of the parasite from this region.
