Abstract

The first record in Hungary of Apororhynchus silesiacus Okulewicz and Maruszewski, 1980 (Acanthocephala), with new data on its morphology.

Abstract

Eight mature specimens (3 males and 5 females) of Apororhynchus silesiacus were found in the small intestine of Erithacus rubecula at Alsóperepuszta, Hungary; this represents a new geographic record. The species is redescribed and figured on the basis of this material. The main differences from the original description concern the dimensions of the proboscis, the testes and the giant nuclei in males.
