novyella novyella novyella is a subgenus of the genus plasmodium - all of which are parasites. the subgenus was created in 1963 by corradetti et al. species in this subgenus infect birds. it unites the avian malaria parasites with small erythrocytic meronts and elongated gametocytes. novyella scientific classification domain: eukaryota clade: diaphoretickes clade: tsar clade: sar clade: alveolata phylum: apicomplexa class: aconoidasida order: haemospororida family: plasmodiidae genus: plasmodium subgenus: novyellacorradetti et al., 1963 species see text taxonomy this subgenus was created on the basis of morphology. subsequent dna studies showed it to be polyphetic. its definition has been revised by landau et al to contain only those species with a white/blue globule in the cytoplasm. several of the species that were included in this subgenus have now been moved to a new subgenus papernaia. species the type species is plasmodium vaughani. plasmodium accipiteris paperna & landau, 2007 plasmodium bambusicolai plasmodium corradettii plasmodium delichoni plasmodium dissanaike de jong, 1971 plasmodium globularis valkiūnas et al., 2008 plasmodium homonucleophilum plasmodium jiangi plasmodium kempi christensen et al., 1983 plasmodium lucens plasmodium megaglobularis valkiūnas et al., 2008 plasmodium merulae corradetti & scanga, 1972 plasmodium mohammedi paperna et al., 2008 plasmodium multivacuolaris valkiūnas et al., 2009 plasmodium nucleophilum toucani syn. p. n. tucani manwell & sessler, 1971 plasmodium pachysomum paperna et al., 2008 plasmodium papernai plasmodium parahexamerium valkiūnas et al., 2009 plasmodium paranucleophilum plasmodium stellatum paperna et al., 2008 plasmodium tenue plasmodium tenuis (laveran & marullaz, 1914) plasmodium unalis plasmodium vaughani novy & mcneal, 1904 description species in the subgenus novyella have the following characteristics: mature schizonts are either smaller than or only slightly larger than the host nucleus. they contain scanty cytoplasm. gametocytes are elongated. sexual stages in this subgenus resemble those of haemoproteus. exoerythrocytic schizogony occurs in the mononuclear phagocyte system a blue, pale blue or white globule, frequently refractory, can be found in the cytoplasm.
