Abstract

The main aim of this paper is to describe first record of Echinochasmus prakashi Gupta & Singh, 1988 which was recorded during the study on biodiversity of helminths of Nycticorax nycticorax from Hamal Lake, Sindh, Pakistan. Helminthological examination revealed a large number of specimens of genus Echinochasmus found in intestine of the host, of which 05 identified as Echinochasmus prakashi Gupta & Singh, 1988. They resemble with it in having spinose and medium sized body, oral sucker terminal, head collar reniform with single row of 22 spines, shape and position of cirrus pouch, testes, ovary and vitellaria. Echinochasmus prakashi is recorded first time from Nycticorax nycticorax and Pakistan is new locality for this species.

Genus Echinochasmus Dietz, 1909 is found throughout the world in birds of family Podicipedidae, Ciconiidae, Ardeidae, Accipitridae, and Anatidae. It contains a number of species that are transmitted to human as food borne trematodes. It transmits infection by way of the ingestion of metacercarial cyst by humans with raw or improperly cooked freshwater fish. Human ingesting cercariae of this species of Echinostome may develop an intestinal trematodiasis referred to as Echinochasmiasis (Rim, 1982; Chai and Lee, 2002 and Ujan et al., 2014). In Pakistan very little work has been done on trematode parasites of birds. Species of genus Echinochasmus Dietz, 1909 reported from Pakistan by Ujan et al., 2014, Dharejo et al., 2010, Channa et al., 2009, Dharejo et al., 2007 and Bhutta and Khan, 1975. These were collected from the Bank Myna Acridotheres ginginianus, House Sparrow Passer domesticus, Pond Heron Ardeola grayii and Paddy Bird Ardeola gyayii. None of the researchers studied Black C
