ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 65. Budapest 1973. Two Fluke Species, Leipertrema vietnaniense sp. n., and Ogmocotyle indica (Bhalerao, 1942) from Rodents in Vietnam (Trematodes)* By I. MATSKÁSI, Budapest Abstract — Two fluke species, Leipertrema vietnaniense sp. n. and Ogmocotyle indica (BHALERAO, 1942) were found in rodents originating from Vietnam; the description of the two species and locality data are given. Dr. G. TOPÁL and the author, research workers of the Hungarian Natural History Museum, Budapest, were on a zoological collecting trip to the Democratic Republic of Vietnam in 1971. As a result of parasitological collecting activity, two fluke species were found in rodents. One of them, relegable to the genus Leipertrema SANDOSHAM, 1951, differed considerably from all known congeners, while the other proved to represent Ogmocotyle indica (BHALERAO, 1942), described from India. I consider the publication of this species worthy, partly because of the new locality, partly because it was hitherto found in India in the digestive organs of cattle, goats, and sheep belonging to the order Artiodaotyla, whereas it was found to occur in rats (Battus sp.) of the order Rodentia in Vietnam. Leipertrema vietnaniense sp. n. (Eigs. 1-2) Host: Gallosciurus macclellandi HORSFIKLD. — Locality: An-phu, District Luc Yen, Province YenBai, Vietnam. — Date of collecting: 3 December, 1971. — Localization: liver, ductus choledochus. — I n tensity: 18 specimens, Diagnosis: A medium large, narrower or broader, lanceolate fluke. Body widest at level of ventral sucker, with a characteristic constriction between oral and ventral suckers. Tegument densely covered with coniform papillae. Oral sucker subterminal. Muscular pharynx emptying into short oesophagus. Oesophagus bifurcating pre-acetabularly into two comparatively short caeca, decurrent appressed to acetabular wall, between testes and acetabulum. Caeca terminating shortly before vitelline glands, far from end of body. Acetabulum considerably more spacious than oral sucker, situated at border of first third of body. Testes oval, minute, largely in the same horizontal level, generally pre-acetabular or only slightly removed from caudal surface of ventral sucker (post-acetabular). Ovarium larger than testes, post-acetabular (in contracted specimens touching acetabular surface). Mehlis-body well developed behind ovarium. Cirrus sac situated intercaecally, anterior to acetabulum. Genital pore opening at or slightly before level of caecal bifurcation ; in strongly contracted specimens base of cirrus sac reaching beyond dorsal surface of ventral sucker. Uteral whorls filling post-acetabular body cavity, their terminal section meandering on dorsal side of ventral sucker to genital pore. Vitellary glands, consisting of few but large follicles, situated bilaterally. * Zoological Collecting Trips of the Hungarian Natural History Museum in North Vietnam (DRV) No. 5.
