Abaligeti-barlang In Table 2 certain species occur in only a few cases, but this is not an expression of their rarity since most of them occur - as shown in Table 3 - more frequently in the company of other species.On the basis of material collected so far, the following flea species of mammals may be considered rare : Chaetopsylla rothschildi Kohaut

; Ischnopsyllus simplex simplex Rothschild; I. simplex mysticus Jordan; I. variabilis (Wagner); Megabothryis walkeri (Rothschild); Palaeopsylla ko hauti Dampf; Peromyscopsylla fallax (Rothschild); Rhadinopsylla isacantha isacantha (Rothschild); R. pentacantha (Rothschild); R. strouhali Smit, hitherto found as a single specimen only and identified conditionally even by its discoverer; Rhinolopho- psylla unipectinata unipectinata (Taschenberg), and Tarsopsylla octodecimdentata octodeclmdentata (Kolenati). As the host species of these fleas are rare in Hungary, their infrequent capture is quite understandable.
