[Redescription of Dictyocaulus noerneri Ralliet et Henry, 1907, parasite of Capreolus capreolus in Europe. Comparison with D. viviparus (Bloch, 1782), a parasite of cattle]

Abstract

Both species are easily distinguished by the shape and the thickness of the buccal ring. In D. noerneri, the buccal ring is 12-14 microns high, kidney like shape in optical section and thick in en face view. In D. viviparus, the buccal ring is 22-25 microns high, triangular shape in optical section and thin in en face view. The taxon Dictyocaulus eckerti Skrjabin, 1931, described from Rangifer larandus in Western Siberia, has been misused to call the Dictyocaulids of european Cervidae. If those are identical to the species of the reindeer, D. eckerti must be synonymysed with D. noerneri, if the two species are different, in any case the Dictyocaulids of european Cervidae must be called D. noerneri.
