microheliella microheliella microheliella is a monotypic genus of protists containing the sole species m. maris, first described in 2012. it has a variety of unusual morphological characteristics which make its broader classification difficult. these include a centrosome with two concentric granular shells and axopodia much simpler in structure than in visually similar protists (other 'heliozoa'). microheliella scientific classification kingdom: chromista phylum: cryptista class: endohelea order: microhelidacavalier-smith 2011 family: microheliellidaecavalier-smith & chao 2012 genus: microheliellacavalier-smith & chao 2012 species: m. maris binomial name microheliella mariscavalier-smith & chao 2012 recent phylogenomic analyses suggest the microhelida are sister to the cryptista, forming a clade called pancryptista, which would be sister to the archaeplastida. cam clade archaeplastida rhodelphidia rhodophyta picozoa chloroplastida glaucophyta pancryptista microheliella maris cryptista palpitia cryptomonada
