New records of suctorians (Ciliophora: Suctoria) as epibionts of aquatic true bugs (Hemiptera: Prosorrhyncha: Nepomorpha) from two regions: Mexico and Eastern Europe

摘要

Here, we provide new records of suctorians (Ciliophora: Suctoria), epibionts of aquatic true bugs (Hemiptera: Prosorrhyncha:udNepomorpha) collected in Ukraine, Belarus and Mexico. The worldwide distribution of the 16 species we found isudupdated, from which, 15 species are new records as epibionts of 15 species of aquatic true bugs. Only for the suctorianudDiscophrya gessneri Matthes, we confirm the previous record (epibiont of Aphelocheirus aestivalis Fabricius). We concludeudthat the relationship between the suctorians and aquatic true bugs is poorly studied and some suctorian genera (DiscophryaudLachmann and Periacineta Collin) inhabit as nepomorphans as other aquatic insects (Coleoptera). However theudhigh degree of specificity at the species level of these genera is evident, for which we provide some possible explanationsudaccording to the group of basibiont.
