On two new species of the trematode genera, Opisthioparorchis Wang, 1980 and Batrachotrema Dollfus and Williams, 1966 (Batrachotrematidae), wih a report of a Chinese species of Opisthoparorchis from anuran amphibian hosts in India

© Zoo Outreach Organisation; www.zoosprint.org Manuscript 1255; Received 09 September 2004; Finally accepted 23 March 2005; Date of publication 21 May 2005 1883 June 2005 | ISSN 0971-6378 During an exploratory survey of the helminth parasite fauna of anuran Amphibia in Nagaland (India) several digenetic trematode species were encountered. Two of these forms, on study, were found to be new to science and belong each to the genera Batrachotrema Dollfus and Williams, 1966 and Opisthioparorchis Wang, 1980. While the former genus has hitherto been reported from Africa (Dollfus & Williams, 1966), China (Wang, 1981; Zhang & Sha, 1985; Liang & Ke, 1988) and Vietnam (Moravec & Sey, 1989) the latter is represented so far in ranid frogs in China. The present communication deals with the description of a new species of each genus, and also forms the first record of the occurrence of these genera in the Indian subcontinent. The occurrence of O. yunnanse Li, 1996 is also reported from Rana liebigii as a new record.
