Order Desmothoracida, the desmothoracids, are a group of heliozoan protists, usually sessile and found in freshwater environments. The adult is a spherical cell around 10-20 μm in diameter surrounded by a perforated organic lorica, or shell, with many radial pseudopods projecting through the holes to capture food. These are supported by small bundles of microtubules that arise near a point on the nuclear membrane. Unlike other heliozoans, the microtubules are not in any regular geometric array, there does not appear to be a microtubule organizing center, and there is no distinction between the outer and inner cytoplasm.
The euglyphids are a prominent group of filose amoebae that produce shells or tests that in most described species is reinforced by siliceous scales, plates, and sometimes spines, but this reinforcement is absent in other species. These elements are created within the cell and then assembled on its surface in a more or less regular arrangement, giving the test a textured appearance. There is a single opening for the long slender pseudopods, which capture food and pull the cell across the substrate.
The tectofilosids are a group of filose amoebae with shells. These are composed of organic materials and sometimes collected debris, in contrast to the euglyphids, which produce shells from siliceous scales. The shell usually has a single opening, but in Amphitrema and a few other genera it has two on opposite ends. The cell itself occupies most of the shell. They are most often found on marsh plants such as Sphagnum.
Gymnophryidae is a small family of amoeboids that lack shells and produce thin, reticulose pseudopods. These contain microtubules and have a granular appearance, owing to the presence of extrusomes, but are distinct from the pseudopods of Foraminifera. They are included among the Cercozoa, but differ from other cercozoans in having mitochondria with flat cristae, rather than tubular cristae.
The Mydidae, or Mydas flies, are a cosmopolitan family of flies. It is a small family, with about 471 species described. They are generally large in size, including the largest known fly, Gauromydas heros. Many of the species, in addition to their large size, are mimics of stinging hymenopterans, especially wasps. Most mydids are found in arid and semiarid regions of the world, but they are also found in other habitats.
Thaumatomonadida is an order of flagellates.
Thaumatomonas is a genus within Imbricatea of the phylum Cercozoa.
Amastigomonas is a genus of protists belonging to a lineage of biciliated zooflagellates known as Apusomonadida. It was first described in 1931 by Henri de Saedeleer. The current use of Amastigomonas is as a descriptive archetype, with no phylogenetic or taxonomic implications. The term "Amastigomonas-like" is used to refer to all apusomonads that lack the 'derived' characteristics of Apusomonas.
The Royal Academy of Fine Arts of Ghent is an art school that is one of the oldest art schools in Belgium. It is a part of the Hogeschool Gent, a Belgium University college.
Alphonse Amédée Trémeau de Rochebrune was a French botanist, malacologist and a zoologist. He was born on 18 September 1836 in Saint-Savin, and died on 23 April 1912 in Paris.
Alexandre De Saedeleer is a Belgian international field hockey player. At the 2012 Summer Olympics, he competed for the national team in the men's tournament. De Saedeleer won the silver medal with Belgium at the 2013 European Championship on home ground in Boom.
Rik De Saedeleer was a Belgian footballer, columnist and television sports commentator.
De Saedeleer is a surname. Notable people include:
Valerius de Saedeleer or Valerius De Saedeleer was a Belgian landscape painter, whose works are informed by a Symbolist and mystic-religious sensitivity and the traditions of 16th-century Flemish landscape painting. He was one of the main figures in the so-called first School of Latem which in the first decade of the 20th century introduced modernist trends in Belgian painting and sculpture.
Musotiminae is a subfamily of the lepidopteran family Crambidae. It was described by Edward Meyrick in 1884
Codonosiga elegans is a species of choanoflagellate in the family Codonosigidae. It may be a species complex containing multiple cryptic species – four distinct genotypes are known.
Granofilosea is a class of cercozoan protists in the subphylum Reticulofilosa. Out of the three groups that were traditionally considered heliozoans: the heliomonads, gymnosphaerids and desmothoracids, the latter were recently grouped into this new class.
Events in the year 1867 in Belgium.
Allogromia terricola is a species of unicellular foraminiferan in the genus Allogromia.
Euglyphia is a group of imbricate protists in the phylum Cercozoa. They are unicellular eukaryotes characterized by a cell body covered in large imbricate scales, and an apical aperture through which they extend either filose pseudopodia or two cilia of different sizes that are not used for gliding.
