Three species of mites (Acari: Mesostigmata) parasitising small mammals in Hungary* Dr. Michal AMBROS Institute of Experimental Biology and Ecology, Slovak Academy of Sciences, Research Station Staré Hory, Czechoslovakia "Three species of mites (Acari: Mesostigmata) parasitising small mammals in Hungary"Ambros, M. - Parasit, hung. 14: 95-97. 1981-82. ABSTRACT. Three species of little-known Mesostigmata are reported from small mammals of the nature reserve Kisbalaton (West-Hungary). Pergamasus septentrionalis (Oudemans, 1902) and Eugamasus bérlései (Willman, 1935) are new to the fauna of Hungary; Microtus agrestis and Arvicola terrestris are newly recorded hosts for Laelaps muris Ljungh, 1977 in this territory. The fauna of mites of the soborder Mesostigmata parasitising small mammals (Insectivora, Rodentia) is not sufficiently known in Hungary. The following data as to ectoparasitic mites of small mammals of this region are available: BALOGH and ROSTÁS (1955) have listed 7 species, MAHUNKA and MOLNOS (1962) 22 species, EROSS and MAHUNKA (1971) 1 species, MRCIAK (1979) 18 species, HAITLINGER (1979) 23 species. BERON (1969) had listed 12 species of mites on bats. Founty-seven species of mites of the suborder Mesostigmata have been now recorded in the territory of Hungary. They were found on the hair of 15 host species (Insectivora and Rodentia). We have found 16 species of those mites during an investigation of nature reserve Kisbalaton (WestHungary) in cooperation of the Slovak Academy of Sciences and the Department of Zoology, Hungarian Natural History Museum during 23rd to 26th, March, 1982. Among them are two species that had not been recovered in Hungary before: Pergamasus septentrionalis and Eugamasus bérlései

. Microtus agrestis and Arvicola terrestris are new hosts for Laelaps muris in Hungary. Identification of those species was done according to EVANS and TILL (1966), MICHERDZINSKI (1969), BREGETOVA (1977). All specimens are prepared and deposited in the Hungarian Natural History Museum, Budapest. COLLECTION DATA 1.
