Phylogenomic Diversity of Marine Crustacean-Infecting Gregarine Apicomplexans Within and Outside the Cephaloidophoroidea

Transcriptomes were generated from 11 new species of crustacean-infecting gregarines and Ganymedes themistos and used in phylogenomic analyses showing all but one crustacean-infecting gregarines primarily do branch with the Cephaloidophoroidea. Lentusidium euphilomedae, found in the seed shrimp Euphilomedes sp., branches very distantly to the Cephaloidophoroidea forming a strongly supported sister to Lecudinoidea
