[Ctenophthalmus rettigi Rothschild, 1908 (Hystrichopsyllidae) fleas of Mesocricetus]

Fleas of Ctenophthalmus rettigi Rothschild, 1908 (12 females, 12 males) collected in 1980 and 1982 in the northern Caucasus in the Levashi District of Dagestan not far from the village of Urma were referred by the authors to the nominative subspecies described from Romania. According to their taxonomic characters fleas of this species, collected in different places of Transcaucasia, are also referred to the nominative subspecies and not to C. rettigi smiti Klein, 1962, as before (Rostigaev, 1967; Tiflov, Skalon, Rostigaev, 1977 and others). The ways of distribution of hosts of C. rettigi fleas are suggested.
