DUDICH, MÉSZÁROS and STOLLMANN, hosts: S. araneus L.; N.fodiens (PENN.), M. arvalis (PALL.) and A

. flavicollis (MELCH.). The occurrence of the eastern, mainly mountain, subspecies of D. dasyenema (ROTHSCHILD) was expected only from the mountainous parts of eastern Hungary (SZABÓ 1975, 1980). This subspecies occurs in Slánske vrchy Mts. in Slovakia (on its Hungarian side the abovementioned material was collected), in the Eastern Beskid mountain range and in the Vihorlat Mts. (DUDICH 1984a) but no specimen was found in the Thais lowland in Slovakia nor in Hungary. D. dasyenema cuspis may occur in Hungary now in the entire eastern part of the country as a possible continuation of its distribution from the mountains of Roumania (Bihor Mts.). Namely, westwards from the locality mentioned above, in the Slovakian part of the Aggtelek karst (Slovensky kras) and in the Bükk Mts. we know the nominate form only. So the valley of the river Hernád seems to be a natural barrier in the distribution of the two subspecies today. The following indexes of infestation were observed (calculated for the two shrew species only): extensity 17.1 %; mean intensity 0.35 and dominance 23.5. Our specimens were collected together with the following taxa from the eastern province: Ctenophthalmus agyrtes kleinschmidtianus PEUS; Palaeopsylla sor ici s s tar ki WAGNER and Hystrichopsylla o. orientális SMIT. The morphological patterns of the males from the Zemplén Mts. are "clear cuspis" found in the Slovak Eastern Carpathians (Fig. 12), but the outline of the 7th sternum in the females is highly variable owing to the introgression influence between the two subspecies along the border of their distribution area (Fig. 13).
