ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 59. PARS ZOOLOGICA 1967. The Distribution of Subspecies of Ctenophthalmus agyrtes in Hungary (Siphonaptera: Hystrichopsyllidae) By F.G.A.M. SMIT, Tring (Great Britain), and I. SZABÓ, Budapest In the greater part of Europe Ctenophthalmus agyrtes is one of the commonest fleas of micromammalia and can be found the year round. Nevertheless, until very recently there has been only one published record of this species from Hungary (DUDICH, 1932, p. 58 — 3 $ from Aggtelek). The recent records of specimens from western Hungary are included in an article on the distribution of C. agyrtes sspp. in neighbouring Austria (SMIT, 1966: 219, Fig. 1). As Ctenophthalmus agyrtes is the classic —though still very imperfectly known — example of subspecification in fleas and as Hungary occupies an important area in the range of several of those subspecies, the material collected mainly by the junior author and his colleagues greatly increases our knowledge of the range of distribution of various forms. We are deeply indebted to Prof. Dr. B. ROSICKY for permitting us to use several records based on material in the extensive collection of fleas in the Parasitological Institute of the Czechoslovak Academy of Sciences, Praha. As subspecies of C. agyrtes can only be satisfactorily differentiated in the male sex, the mapped distribution is based solely on male specimens. The following five subspecies occur in Hungary (Fig. 1): C. agyrtes agyrtes (HELLER, 1896) — Only known from Rajka (though the one male seen from there is not 100% typical; however, atypical specimens are common in the periphery of the distribution range of subspecies) and, as is obvious from the distribution map (Fig. 1), this subspecies is doubtless confined to the northermost part of the Győr-Sopron county. C. agyrtes bosniens WAGNER, 1930 — Except for the above-mentioned nominate subspecies, this is the only subspecies occurring in this country west of the Duna; apparently only in the south, near Baja, does a. bosniens occur on the other side of the river (however, see below sub "Intergrades"). C. a. bosniens has been collected at: Baja, Bakonybél, Bakonynána, Balatonlelle, Iharkút, Kaposmérő, Kisbalaton, Kőris-hegy, Németbánya, Őriszentpéter, Pisznice-hegy, Sárcsikút, Szabadegyháza, Szalafő, Szőce, Szuadó-völgy and Tatabánya. The single male we have seen from Szuadó-völgy veers somewhat towards agyrtes serbicus WAGNER, 1930; additional material from the Baranya county will eventually show whether or not intermediate populations occur in the southernmost parts of the country. SMIT (1966, 1967) discussed the distribution of this subspecies and pointed out that no specimens of agyrtes have been available for study from the large area between the type locality of a. bosniens (i.e. the Igman mts, just S.W. of Sarajevo, Yugoslavia) and the places marked on our Fig. 1.
