We characterized partial sequences of 18S rDNA from sedge warblers infected with a parasite described previously as Hepatozoon kabeeni. Prevalence was 47% in sampled birds. We detected 3 parasite haplotypes in 62 sequenced samples from infected animals. In phylogenetic analyses, 2 of the putative Hepatozoon haplotypes closely resembled Lankesterella minima and L. valsainensis. The third haplotype grouped in a wider clade composed of Caryospora and Eimeria. None of the haplotypes showed resemblance to sequences of Hepatozoon from reptiles and mammals. Molecular detection results were consistent with those from microscopy of stained blood smears, confirming that the primers indeed amplified the parasite sequences. Here we provide evidence that the avian Hepatozoon-like parasites are most likely Lankesterella, supporting the suggestion that the systematic position of avian Hepatozoon-like species needs to be revised.
