Two New Species of the Genus Pallisentis Van Cleave, 1928 (Acanthocephala: Quadrigyridae) from the Intestine of Channa punctatus (Bloch, 1793) from the River Gomti at Lucknow, India
BACKGROUND: Acanthocephalans are fish parasites of worldwide distribution, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. No diagnostic tool is available except postmortem investigations and identification by parasitologists. The aim of present study was to e...

description | BACKGROUND: Acanthocephalans are fish parasites of worldwide distribution, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. No diagnostic tool is available except postmortem investigations and identification by parasitologists. The aim of present study was to explore and assign taxonomical status to Pallisentis species prevalent in food fishes of river Gomti, Lucknow, India. METHODS: A survey of fishes of river Gomti was carried out during the year 2011–2013. Acanthocephalans recovered from the intestine of Channa punctatus were kept in refrigerator for eversion of proboscis, fixed in A.F.A. fixative (50% alcohol, formalin and acetic acid in ratio of 100: 6: 2.5) for 24 hours further preserved in 70% ethanol. Camera Lucida diagrams of acetoalum carmine stained permanent mounts were made for morphometric studies. RESULTS: Two new species of genus Pallisentis were identified and named as P. channai n. sp. and P. vinodai n. sp., their taxonomical status is based on major characters of proboscis hooks, spines of collar and trunk region, cement gland nuclei. On average 9 fishes were found infected with Pallisentis spp. out of 60 fishes examined randomly. CONCLUSION: Pallisentis spp. are important parasitic infection in Channidae fishes with the prevalence rate of 15%. Two new species of Pallisentis recognized from Channa punctatus of river Gomti, Lucknow, India and diagnostic features of genus are given. |
