Article
New data on the species diversity and morphology of centrohelid heliozoans in freshwater, marine, and soil habitats of Ukraine were obtained. Cell coverings (scales and spicules) were observed using scanning and transmission electron microscopy. Eighteen species from seven genera of centrohelids and unidentifiable Heterophrys-like organisms were re...
Article
Kinetoplastids represent a stockpile of undiscovered protist diversity. Free-living members of this group have been studied less intensively compared to their important parasitic relatives. We have isolated a new soil-dwelling bacteriotrophic kinetoplastid, which is described here as a new genus and new species, Avlakibodo gracilis gen. et sp. nov....

Telonemia is a poorly known major phylum of flagellated eukaryotes with a unique combination of morphological traits. Phylogenomics recently revealed the phylogenetic position of telonemids as sister to SAR, one of the largest groups of eukaryotes, comprising Stramenopiles, Alveolata and Rhizaria. Due to this key evolutionary position, investigatio...
Article
Marophrys is a genus of spicules-bearing centrohelids belonging to Heterophrys-like organisms (HLO’s). Here Marophrys nikolaevi spec. nov. is described. Four strains were isolated from brackish waters (16–22 ppt) of the Tuzlukkol’ River, the Tuzluchnoe Lake (South Urals, Russia) and the Black Sea. All the strains were characterised with light micro...

A new genus and species of centrohelid heliozoans, Triangulopteris lacunata gen. et sp. nov. (Pterocystidae Cavalier-Smith and Heyden, 2007), from four geographically remote locations (the Crimean Peninsula, the Dnieper Lowland (the East European Plain), Franz Josef Land, and the Kolyma Lowland (North–Eastern Siberia) was examined using light and e...

The morphology of the siliceous scales and organic spicules of centrohelid heliozoans collected from two river sites and one marine site in South Korea has been investigated. Five species including one subspecies, one centrohelidian identified at the genus level, and Heterophrys-like organisms were examined. New species, Pterocystis jongsooparkii s...
Article
The species diversity, distribution, and morphological features of centrohelid heliozoans (Centroplasthelida) (Haptista: Centroplasthelida Febvre-Chevalier et Febvre, 1984) from freshwaters of Central and Southern Vietnam have been studied using scanning electron microscopy (SEM). Twelve species, belonging to Acanthocystidae, Choanocystidae, Pteroc...
Article
The species diversity and morphology of centrohelid heliozoans from the Black Sea shoreline (Southern Crimea) were studied with scanning and transmission electron microscopy to supplement our knowledge on the species composition and the features of the siliceous covering of centrohelids. Six species and forms (Acanthocystis trifurca, A. turfacea, P...
Conference Paper
Full-text available
Centrohelid heliozoa is a monophyletic group of protists with siliceous (rarely organic) tangental or radial scales, and one genus, Oxnerella, without scales. Like some heliozoans, centrohelids are obligate passive predators, floating in the water or gliding along a substrate and capturing prey with axopodia. The species composition and morphology...

DOI: 10.21685/1680-0826-2017-11-1-1 The species composition and morphology of centrohelid heliozoa collected from mire water bodies of different types in the North of the European part of Russia were studied. Eighteen specie...
