Abstract
A new endoparasitic fluke,
Cephalogonimus yamunii n.sp. is described from the intestine of freshwater fish
Xenentodon cancilla (Belonidae). The worms could be differentiated from
C. amphiumae (Chandler
1932),
C. apognichthysi (Gupta and Puri
1982),
C. hanumanthai (Agrawal and Agarwal
1984),
C. salamandrus (Dronen and Lang
1974),
C. simhai (Singh
2010) and
C. vesicaudus (Nickerson
1912) in a unipartite seminal vesicle, genital pore subterminal anteriorly, opening at the hind end of oral sucker, equatorial or sub-equatorial testes, besides other morphological attributes of shorter body and pharynx, larger oesophagus and oral sucker, smaller ventral sucker, testes, cirrus sac and ovary, and a terminal excretory pore. Taxometric substantiation has been presented by using Polythetic Divisive Classificatory System, and ecological attributes have been evaluated to validate specific distribution patterns in population dynamics of the new species in simultaneous contributions.
