The following three species were not captured during our samplings: Cystobranchus fasciatus, Trocheta bykowskii and Glossiphonia verrucata. There are many rare species in the collection {Glossiphonia paludosa, Placobdella costata, Batracobdelloides moogi, Alboglossiphonia hyalina, Piscicola haranti, Caspiobdella fadejewi, Cystobranchus respirons, Dina apathyi, Trocheta riparia) and the following remarks discuss their distribution and the literature related to them. Placobdella costata — Literature data: Orgovány, Balatonfenyves (Soós 1963), Bátorliget (Nesemann 1991), Lipót (Nesemann 1997), Biharugra (Juhász et al. 1998). Authors revealed its existence at four sampling locations. Hungarian distribution is shown on Fig. 1. This is an ectoparasite species occurring most often on the Hungarian marshland turtle (Emys orbicularis). Apart from its typical host, it also occurs on higher plants. Wetlands of high natural value, bogs and slow-flowing water bodies contain isolated populations of this species. It prefers waters, where Stratiotes aloides occurs. Alboglossiphonia hyalina — Only a limited number of Hungarian data exist on this species (Csányi 1996; Nesemann 1998, Juhász et al. 1998). Authors found specimens in the Gyügérzug marsh at Öcsöd (Fig. 1). It is a rare, sporadically occurring species, good indicator of natural wetlands, marshes and dead-arms of rivers. It is a parasite of the Lymnaea species. Its occurrence is temporal, occasionally can disappear for a prolonged time period.
