RESULTS Flea occurrence in dormouse nests The following flea species and subspecies were found in dormouse nests (Muscardinus avellanarius L., Glis glis L., Dryomys nitedula Pall) and in combined nests: Hystrichopsylla orientális orientális Smit, 1956 Ctenophthalmus solutus solutus Jordan et Rothschild, 1920 Ctenophthalmus agyrtes agyrtes (Heller, 1896) Ctenophthalmus agyrtes peusianus Rosicky, 1955 Ctenophthalmus agyrtes kleinschmidtianus Peus, 1950 Ctenophthalmus assimilis assimilis (Taschenberg, 1880) Ctenophthalmus uncinatus (Wagner, 1898) Doratopsylla dasycnema dasycnema (Rothschild, 1897) Dasypsyllus gallinulae gallinulae (Dale, 1878) Megabothris turbidus (Rothschild, 1909) Nosopsyllus fasciatus (Bosc, 1800) Ceratophyllus enefdeae enefdeae Ioff, 1950 Ceratophyllus fringillae (Walker, 1856) Ceratophyllus garei (Schrank, 1803) Ceratophyllus hirundinis (Curtis, 1826) Ceratophylluspullatus Jordan et Rothschild, 1920 Ceratophyllus tribulis Jordan, 1926 Ceratophyllus sciurorum sciurorum (Schrank, 1803) The occurrence of these species in various localities on diverse hosts is given in Tables 1-4.

Its absence is conspicuous solely in the locality of áúr (not a single specimen of this species was collected from 22 nests of
