A new heterolobosean amoeba, Selenaion koniopes n. gen., n. sp., was isolated from 73‰ saline water in the Wieliczka salt mine, Poland. The amoeba had eruptive pseudopodia, a prominent uroid, and a nucleus without central nucleolus. Cysts had multiple crater‐like pore plugs. No flagellates were observed. Transmission electron microscopy revealed several typical heterolobosean features: flattened mitochondrial cristae, mitochondria associated with endoplasmic reticulum, and an absence of obvious… 

Characterization of a Deep‐Branching Heterolobosean, Pharyngomonas turkanaensis n. sp., Isolated from a Non‐Hypersaline Habitat, and Ultrastructural Comparison of Cysts and Amoebae Among Pharyngomonas Strains

Propose isolate LO as a new species, Pharyngomonas turkanaensis n.

A New Halophilic Heterolobosean Flagellate, Aurem hypersalina gen. n. et sp. n., Closely Related to the Pleurostomum‐Tulamoeba Clade: Implications for Adaptive Radiation of Halophilic Eukaryotes

This isolate of a biflagellate from a hypersaline water of 342‰ salinity shared several morphological features with typical halophilic heterolobosean flagellates, indicating that this new clade is composed almost entirely of obligate Halophilic taxa.

Dactylomonas gen. nov., a Novel Lineage of Heterolobosean Flagellates with Unique Ultrastructure, Closely Related to the Amoeba Selenaion koniopes Park, De Jonckheere & Simpson, 2012

Phylogenetic analysis of the SSU rRNA gene showed that Dactylomonas is closely related to the amoeba Selenaion, the deepest‐branching lineage of Tetramitia, and has several features uncommon in Heterolobosea, including a microtubular corset and a finger‐like projection on the proximal part of the recurrent flagellum.

A New Heterolobosean Amoeboflagellate, Tetramitus dokdoensis n. sp., Isolated from a Freshwater Pond on Dokdo Island in the East Sea, Korea

The strain isolated from the Dokdo Island is proposed as a novel species, Tetramitus dokdoensis n.

Accumulation patterns of intracellular salts in a new halophilic amoeboflagellate, Euplaesiobystra salpumilio sp. nov., (Heterolobosea; Discoba) under hypersaline conditions

This work isolates a novel halophilic microbial eukaryote from hypersaline water of 134 practical salinity units (PSU) in a solar saltern and proposes that the isolate, Euplaesiobystra salpumilio, is a novel species.

Morphology and Phylogenetic Analyses of Three Novel Naegleria Isolated from Freshwaters on Jeju Island, Korea, During the Winter Period

Three novel Naegleria were isolated from freshwaters on Jeju Island, Korea, during winter, and the phylogenetic analyses consistently revealed that the isolates are members of the NaEGleria group, however, the isolate differ from other species in both phylogenetic trees.

Neovahlkampfia nana n. sp. Reinforcing an Underrepresented Subclade of Tetramitia, Heterolobosea

The study provides robust genetic evidence that a newly isolated naked ameba with morphological and ultrastructural features indicative of Heterolobosea is a new species and points to the potentially dubious validity of some current nominal species of Hetteroloboseda that differ from one another in just one or two base positions.

Survey on diversity of marine/saline anaerobic Heterolobosea (Excavata: Discoba) with description of seven new species.

Amoebae, cysts and the ultrastructure of the genus Pseudoharpagon are presented for the first time and show that all the strains belong to the family Psalteriomonadidae, the main anaerobic lineage of Heterolobosea.



Monopylocystis visvesvarai n. gen., n. sp. and Sawyeria marylandensis n. gen., n. sp.: two new amitochondrial heterolobosean amoebae from anoxic environments.

In phylogenetic analyses of small-subunit rRNA gene sequences, Monopylocystis visvesvarai, Sawyeria marylandensis and Psalteriomonas lanterna converge to form a single clade of non-aerobic (anaerobic/microaerophilic) heteroloboseans.

Morphologic and Molecular Identification of Naegleria dunnebackei n. sp. Isolated from a Water Sample

The organism was isolated from a water sample taken from drinking troughs associated with cases of primary amoebic meningoencephalitis in cattle at a ranch in southern California, and did not kill young mice upon intranasal inoculation suggesting that it was not pathogenic.

Tetramitus thermacidophilus n. sp., an Amoeboflagellate from Acidic Hot Springs

Thermophilic and acidophilic amoeboflagellate isolated from acidic hot springs in the Caldera Uzon and Pisciarelli Solfatara is described and sequence comparisons confirm that T. thermacidophilus is a novel species within the genus Tetramitus and that both isolate belong to that species.

Three New Limax Amoebae Isolated from Marine Surface Sediments: Vahlkampfia caledonica N. Sp., Saccamoeba marina N. Sp., and Hartmannella vacuolata N. Sp.

Three new limax amoebae, isolated from marine, surface sediment samples are described using light microscopic and fine structural features, providing additional evidence that limaxAmoEBae may be more abundant in marine sediments that realized previously.

Ultrastructure of the amoebo-flagellate Protonaegleria westphali

It is assumed that Protonaegleria is related more closely to Naeglerian than to Tetramitus, due to the morphological characteris of the flagellates and cysts of the genus ProtonAeglerIA.
