On a new digenetic trematode Neopodocotyle mastacembelli n. sp. (Family: Opecoelidae Ozaki, 1925) from the intestine of fresh water fish Mastacembelus armatus (Lacepede.) of Matatila Reservoir Bundelkhand region, Jhansi (UP), India. _

Abstract

The present study was aimed that determining the intestinal digenetic trematodes found in fishes of Matatila Reservoir Bundelkhand region, Jhansi. The new species Neopodocotyle mastacembelli n.sp reported from fresh water fish Mastacembelus armatus (Lacepede.). N. mastacembelli n.sp. Characterized by having aspinose body; presence of short, tubular, pre-pharynx; globular, muscular pharynx; post-equatorial, intercaecal, apart from each other, unequal, tandem testes. Anterior testis was larger than posterior one. Ovary, oval, post-equatorial, pre-testicular, intercaecal; elongated sac like cirrus sac extends from right side of equatorial region, occupying the entire posterior-lateral margin of ventral sucker and finally ends at the middle level of oesophageal region on its right side; opening of genital pore at oesophageal region on its right side; vitelline follicles, spherical extends from little anterior to intestinal bifurcation up to hind end of the body; eggs, oval and operculated. N. mastacembelli n.sp. was collected from M. armatus (Lecepede.) on added one more host to the list of hosts recorded from India.
