Phyllopharyngea

Belongs within: Alveolata.Contains: Cyrtophoria. The Phyllopharyngea are a group of ciliates with a radial array of microtubular ribbons around the oral region (Adl et al. 2012). Characters (from Adl et al. 2012): Ciliated stage with somatic kineties mostly as monokinetids that each have a lateral kinetodesmal fibril, a reduced or absent transverse microtubular ribbon that… Continue reading Phyllopharyngea

Choreotrichida

Belongs within: Spirotricha.Contains: Strombidinopsidae, Tintinnina, Strobilidiidae. The Choreotrichida are a group of ciliates united by a closed adoral zone of membranelles (secondarily opened slightly in Parastrombidinopsis) and hypoapokinetal stomatogenesis in a pouch (Agatha & Strüder-Kypke 2007). <==Choreotrichida [Choreotrichia, Strobilidiina]AS-K07 | i. s.: ClimacocylisAS-K07 | CodonariaAS-K07 | ProplectellaAS-K07 | Lynnella Liu et al. 2011 [Lynnellida, Lynnellidae]AB19… Continue reading Choreotrichida

Peridiniaceae

Belongs within: Peridiniales.Contains: Peridinium. The Peridiniaceae are a group of dinoflagellates with a distinct cingulum, containing four to six cingular plates, and at least one intercingular boundary on the dorsal surface (Fensome et al. 1993). Characters (from Fensome et al. 1993): Test with four Kofoid apical plates; five postcingular plates; cingulum distinct with four to… Continue reading Peridiniaceae

Cribroperidinioideae

Belongs within: Peridiniphycidae. The Cribroperidinioideae are a group of dinoflagellates known as fossil cysts from the Middle Jurassic to the Miocene (Fensome et al. 1993). Characters (from Fensome et al. 1993): L-type ventral organisation; dextral torsion present; apical pore complex contacted by four or five plates; six Kofoid precingular plates, with sixth (1i) pentagonal and… Continue reading Cribroperidinioideae

Oodiniaceae

Belongs within: Dinoflagellata. The Oodiniaceae are a group of dinoflagellates exhibiting an invasive parasitic stage (Fensome et al. 1993). Characters (from Fensome et al. 1993): Parasitic trophont generally suboval to fusiform in outline, not exhibiting a typical dinoflagellate form; invasive organelle consisting of complex rhizoid-like absorptive structure; amphiesma usually pelliculate, occasionally tabulate. Reproduction by palintomic… Continue reading Oodiniaceae

Sporozoa

Belongs within: Myzozoa.Contains: Aconoidasida, Eimeriorina, Adeleorina, Eugregarinorida. The Sporozoa is a group of unicellular organisms parasitic on animals, characterised by the presence of an apical complex at one end of the cell containing organelles (rhoptries and micronemes) that secrete enzymes used in piercing the membrane of host cells. In sporozoans other than the Aconoidasida, the… Continue reading Sporozoa

Cladopyxiineae

Belongs within: Peridiniales.Contains: Broomeoideae. The Cladopyxiineae are a group of dinoflagellates known from the latest Triassic to the present day, characterised by a partiform hyposome with the posterior sulcal homologue consistently within the sulcus. Characters (from Fensome et al. 1993): Tabulation partiform: first antapical homologue (Y) contacting distalmost postcingular plate (VI); posterior sulcal homologue (Z)… Continue reading Cladopyxiineae

Dinophysiphycidae

Belongs within: Peridinoidia.Contains: Dinophysiales, Prorocentrum. The Dinophysiphycidae was defined by Fensome et al. (1993) to include dinoflagellates that possess a sagittal suture together with a cingulum and a sulcus. However, the same publication also suggested that this group was paraphyletic with regard to the Prorocentraceae, which have lost the cingulum and sulcus. Dinophysiphycidae [Dinophysidophyceae, Dinophysoidia]… Continue reading Dinophysiphycidae

Characters (from Fensome et al. 1993): L-type ventral organisation; neutral to sinistral torsion. Four climactal (1u, B, C, A) plates present contacting the apical pore complex, not including Cv… Continue reading Leptodinioideae

Erythropsidinium

Belongs within: Gymnodiniineae. Erythropsidinium is a genus of marine phagotrophic dinoflagellates found in warm and temperate waters, characterised by the possession of a complex ocelloid and a contractile tentacle-like structure called a piston (Gómez 2008). Characters (from Gómez 2008): Cell body globular, gymnodinioid, 70-120 µm in length (excluding piston), ~45-60 µm in width. Cell body… Continue reading Erythropsidinium
