The Aconoidasida are a class of apicomplexan parasites created by Mehlhorn et al in 1980.[1]
Description[edit]
Organisms in this class bear a tip at one end of their outer membrane. This apical complex includes vesicles called rhoptriesand micronemes, which open at the anterior of the cell. These secrete enzymes that allow the parasite to enter other cells. The tip is surrounded by a band of microtubules, called the polar ring. As the name indicates, Aconoidasida (from Greek: negative prefix a- = "lacking") lack a conoid (they do have one only during the ookinete stage) in contrast to the class Conoidasida which have one throughout their life cycle.

Haemosporidiasina (Haemosporidia) is a subclass of apicomplexans described by Jacques Euzéby in 1988.[1] The taxon is very similar to Aconoidasida.
Taxonomy[edit]
Haemosporidiasina is divided into 2 orders:
Order Chromatorida (with pigmented intraerythrocytic parasites)
Suborder Laveraniina
- Family Plasmodiidae
- Genus Bioccala Landau et al 1984
- Genus Biguetiella Landau et al 1984
- Genus Billbraya Paperna & Landau 1990
- Genus Dionisia Landau et al 1980
- Genus Hepatocystis Miller 1908
- Genus Mesnilium Misra, Haldar & Chakravarty 1972
- Genus Nycteria Garnham and Heisch 1953
- Genus Plasmodium Marchiafava & Celli 1885
- Genus Polychromophilus Landau et al 1984
- Genus Rayella Dasgupta 1967
- Genus Saurocytozoon Lainson & Shaw 1969
- Genus Vetufebrus Poinar 2011
- Family Haemoproteidae
- Genus Johnsprentia Landau, Chavatte & Beveridge 2012
- Genus Haemocystidium Castellani and Willey 1904, emend. Telford 1996
- Genus Haemoproteus Kruse 1890 [2][3]
- Genus Paleohaemoproteus Poinar and Telford 2005
- Genus Sprattiella Landau et al 2012
Order Achromatorida (with non-pigmented intraerythrocytic parasites)
Suborder Babesiina includes agents of piroplasmosis sensu stricto
- Family Babesiidae This family excludes species that undergo schizogony in lymphocytes before parasitizing erythrocytes: such species belong to the genus Theileria
- Genus Babesia Starcovici 1893
- Genus Entopolypoides Mayer 1933
- Genus Echinozoon Garnham 1951
- Genus Microbabesia Sohns 1918
- Genus Rangelia
- Genus Tunetella Brumpt & Lavier 1935
- Family Haemohormidiidae has several genera, including:
- Genus Cardiosporidium Van Gaver & Stephan 1907
- Genus Cristalloidophora Porchet 1978
- Genus Dobellia Brumpt 1913
- Genus Echinococcidium Brasil 1902
- Genus Globidiellum Eisen 1895
- Genus Haemohormidium Léger & Duboscq 1910
- Genus Joyeuxella Brasil 1902

- Genus Sauroplasma Starcovici 1893
- Genus Spermatobium Garnham 1951
- Genus Toxocystis Henry 1910
- Genus Trophosphaera du Toit 1938
Suborder Theileriina includes parasites of erythrocytes and diverse white blood cells with sexual reproduction by exoerythrocytic or by exo- and endoerythrocytic schizogony.
- Family Theileriidae du Toit 1918
- Genus Theileria Bettencourt, Franca and Borges 1907
