Analysis of haemosporidian DNA from collected black flies in Mississippi found nine Leucocytozoon species’ DNA sequences that differed those previously known. A phylogenetic analysis—which looks at how species or sequences are evolutionarily related to each other—shown in this phylogenetic tree (cladogram) confirmed that some of the Leucocytozoon lineages group together but don’t seem closely related to any known lineages.
