Flea species new for the Hungarian fauna. VI. By A. DUDICH and I. SZABÓ (Received December 1, 1982) Abstract: Two species of fleas from small mammals are reported: Hystrichopsylla talpae talpae (Curtis) 1826 and Ctenophthalmus uncinatus uncinatus (Wagner) 1898 as new to Hungary. With these two taxa the number of flea species and subspecies in the Hungarian fauna has increased to 63. Two flea taxa new for the Hungarian fauna were collected from the bodies of small mammals in the year of 1982: Hystrichopsylla talpae talpae (Curtis) 1826. 1 cT; locality: Nagyvisnyó, Bán völgye (Com. Heves), 20 March, 1982, leg. A. Stollmann. Host: Apodemus flavicollis (Melchior). The eastern congeneric species H. orientális orientális (Smit) was only known from lowland and mountainous part of Hungary (SZABO, 1975). In the light of recent investigations in the Slovakian part of the Western Carpathians (DUDICH, 1982, 1983) we supposed the precence of the western species of this genus in the mountains of North Hungary. The only specimen was collected in a deep valley of the Bükk Mts. (450 m above sea level) on yellow necked mouse. The eastern species H.o. orientális (Smit) was collected in the southern parts of the Bükk Mts. too, but no case of syntopic occurrence of the two species has so far been recorded. The distribution of the two Hystrichopsylla species in Hungary is probably similar since we know them from West Slovakia, i.e. the first on is limited to the Northern Mountains (Bükk Mts. and probably Mátra Mts. and Börzsöny Mts.). The second one, H.o. orientális is distributed in the remaining part of the country. This species is probably penetrating into the mountains along streams and woodless valleys. This assumption can be explained as a secondary effect caused by antrhopic transformation of the original ecosystems.
