Parasit. Hung. 11. 1978 Parasitic Nematodes of Clethrionomys glareolus (Rodentia) in Hungary Dr. Ferenc MÉSZÁROS Zoological Department of the Hungarian Natural History Museum, Budapest "Parasitic nematodes of Clethrionomys glareolus (Rodentia) in Hungary" - Mészáros, F. - Parasit. Hung. 11. 87-100.1978. ABSTRACT. Ten species of nematodes are reported from the bank vole in Hungary: Heligmosomum mixtum

, Heligmosomoides glareoli

, H. poly gyrus, Tricho strongylus retortaeformis, Angiostrongylus (P. ) dujardini, Mastophorus muris, Syphacia petrusewiczi, S. nigeriana, CapiUaria annulosa, Trichocephalus muris

. The bank vole (Clethrionomys glareolus /Schreber, 1780/) is represented by several subspecies in Europe (excluding S. Europe), West Siberia, the Altai Mountains, Central Asia and Asia Minor. Parasitic helminths as well as nematodes of this vole have been studied by numerous authors. Although PROKOPIC and GENOV (1974), then TENORA and ZEJDA (1974), have summarized the results of the investigations regarding faunistics, taxonomy and interspecific correlation, we still have no clear picture of the parasitic nematodes of C. glareolus. There is also a great need of a systematic revision of the parasitic nematodes living in the bank vole. TENORA and MÉSZÁROS (1971, 1975) have reported Heligmosomum mixtum and Sypha cia petrusewiczi from Hungary. Material and Methods Between 1964 and 1976 there have been collected 485 C. glareolus in various parts of Hungary, with the use of snap traps and live traps. Collectings were made by former and present staff members of the Parasitological Section of the Zoological Department of the Hungarian Natural History Museum: Dr. I. MATSKÁSI, dr. F. MÉSZÁROS, dr. É. MURAI, Mr. I. SZABÓ, Mrs. E. VAJDA, Miss A. MÁTÉ; further by dr. G. TOPÁL mammalogist (Mammal Section of the same institution), Mr. M. JANISCH parasitologist (Dept. of Parasitology, University of Veterinary Sciences, Budapest), Mr. G. ILOSVAY and Mr. T. SZÍTTA of the Natural History Museum, Zirc. Nematodes were fixed in hot Barbagallo solution. For identification they were made translucent by lactophenol. Faunistics and Taxonomy Of 485 dissected C. glareolus, 149 (30.7%) were found to be infected by nematodes. In the course of investigation, the author verified the occurrence often species. Description of six of them is given here. These are Heligmosomum mixtum Schulz, 1954, Heligmoso moides glareoli Baylis, 1928, Angiostrongylus (P. ) dujardini Drozdz et Doby, 1954, Masto phorus muris (Gmelin, 1790), Syphacia petrusewiczi Bernard, 1966, CapiUaria annulosa (Dujardin, 1843). Of the other four, the description of Syphacia nigeriana (Baylis, 1928) was al-
