New phagotrophic euglenoid species (new genus Decastava; Scytomonas saepesedens; Entosiphon oblongum), Hsp90 introns, and putative euglenoid Hsp90 pre-mRNA insertional editing [PDF]

European Journal of Protistology, 2016
We describe three new phagotrophic euglenoid species by light microscopy and 18S rDNA and Hsp90 sequencing: Scytomonas saepesedens; Decastava edaphica; Entosiphon oblongum. We studied Scytomonas and Decastava ultrastructure. Scytomonas saepesedens feeds when sessile with actively beating cilium, and has five pellicular strips with flush joints and ...

Some new and rare Euglenophyce from the State of São Paulo, southern Brazil Algumas novas e raras Euglenophyceae no Estado de São Paulo, Sul do Brasil

Acta Botânica Brasílica, 1987
Occurrence is reported from the region of the city of São Paulo, southern Brazil, of two euglenoid flagellates (Euglenophyceae). These are very rare, and thus very poorly known members of the class: Scytomonas major (Berliner) Lemmermann and Scytomonas ...

On sexual reproduction in euglenoids, a tribute to Berthe Biecheler

Phycologia, 2019
Sexual reproduction in euglenoid flagellates is poorly known. The most recent report appears to be by Mignot from 1962 in a species of the rather unusual heterotrophic genus Scytomonas. We recently came across a paper by Biecheler from 1937, in which she

Molecular phylogenetics of sessile Dolium sedentarium, a petalomonad euglenid

Journal of Eukaryotic Microbiology, Volume 70, Issue 5, September/October 2023., 2023
Abstract The euglenids are a species‐rich group of flagellates with varying modes of nutrition that can be found in diverse habitats. Phagotrophic members of this group gave rise to phototrophs and hold the key to understanding the evolution of euglenids as a whole, including the evolution of complex morphological characters like the euglenid pellicle.

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes

Journal of Eukaryotic Microbiology, Volume 66, Issue 1, Page 4-119, January/February 2019., 2019
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

Phylogenetic Placement and Morphological Description of Three Species of Heterotrophic Euglenids (Euglenozoa) From Arizona: Scytomonas flumensis n. sp., Ploeotia protuberantia n. sp., and Hokulea pusilla comb. nov

Journal of Eukaryotic Microbiology
Euglenids are microbial flagellates best known for their highly flexible photosynthetic species (e.g., Euglena gracilis), though many heterotrophic groups remain poorly characterized at both molecular and ultrastructural levels.

A Revised Understanding of Petalomonad Diversity (Petalomonadida; Euglenida) Enabled by a Cultivation Approach, With Five New Species and Two New Genera

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Euglenids are an important group of free‐living phototrophic, osmotrophic, or phagotrophic protists, with most of the phylogenetic diversity represented by phagotrophs. One major subgroup of phagotrophs is the petalomonads: rigid, often relatively small cells with few pellicle strips (usually 4–8).
