Study of Caryophyllidean (Capingentidae: Pseudobatrachus) tapeworms of fresh water fishes of Bundelkhand region of Madhya Pradesh, India: Part-III

Abstract

Presently eight species are reported from the World in the genus, Pseudobatrachus, Pathak and Srivastav, 2005 i.e. P. chandrai Pathak and Srivastav, 2005; P. moolchandrai Srivastav et al, 2006; P. chandlaensis Sahu, 2007; P. madhyapradeshensis, Khare, 2008; P. chhatrasali Sahu et al, 2009; P. Sengarii Singh, 2009; P. kenensis Srivastav et al, 2010 and P. ramchandrai, Srivastav and Aditya, 2010. The present form is the ninth one from the Indian subcontinent as well as from the whole world and differs on the basis of various morphometric character viz. size of worm, size and shape of scolex, presence of bothridea and grooved rostellum, size of neck, size and number of testes, size of cirrus pouch, presence of internal seminal vesicle, size of ovary and shape of ovarian lobes, size of vitellaria and their distribution, presence of receptaculum seminis, size of uterus, size and type of eggs and their hosts. The caryophyllidean is unique among cestoidea in having monopleuroide body plane, i.e. without internal or external proglottidization and with a single set of reproductive organ. Thus it is provisionally accommodated as P. ramsagarensis n. sp.
