Morphology of cystacanths of some acanthocephalans from aquatic and terrestrial intermediate hosts in the Ukraine.

Abstract

This paper presents data on cystacanth larvae of the following acanthocephalans found in intermediate hosts (aquatic and terrestrial crustaceans and beetles) collected during the period 1985-1993 in different localities in the Ukraine: Polymorphus cincli from Gammarus balcanicus; Polymorphus magnus from Gammarus lacustris; Prosthorhynchus cylindraceus from Armadillidium vulgare and Armadillidium versicolor; Sphaerirostris teres from A. versicolor; Macracanthorhynchus hirudinaceus from Cetonia aurata and Pimelia subglobosa; Macracanthorhynchus catulinus from Anatolica eremita; Mediorhynchus petrotschenskoi from Pimelia subglobosa, Anatolica eremita and Tentyria taurica.All species, with the exception of P. magnus, are described and figured. The cystacanth of M. petrotschenskoi is described here for the first time, and the reports of the cystacanths of P. cincli, S. teres and M. catulinus are new geographic records both for the Ukraine and Europe.
