Myolaimidae is a family of nematodes in the order Rhabditida. It consists of two genera, Myolaimus and Deleyia . [3]
Deleyia Holovachov & Boström, 2006 [4]
Two species are recognized: [5]
Myolaimus Cobb, 1920 [6]
16 species are recognized: [7]
Acanthocheilonema is a genus within the family Onchocercidae which comprises mainly tropical parasitic worms. Cobbold created the genus Acanthocheilonema with only one species, Acanthocheilonema dracunculoides, which was collected from aardwolf in the region of South Africa in the nineteenth century. These parasites have a wide range of mammalian species as hosts, including members of Carnivora, Macroscelidea, Rodentia, Pholidota, Edentata, and Marsupialia. Many species among several genera of filarioids exhibit a high degree of endemicity in studies done on mammalian species in Japan. However, no concrete evidence has confirmed any endemic species in the genus Acanthocheilonema.
Androdioecy is a reproductive system characterized by the coexistence of males and hermaphrodites. Androdioecy is rare in comparison with the other major reproductive systems: dioecy, gynodioecy and hermaphroditism. In animals, androdioecy has been considered a stepping stone in the transition from dioecy to hermaphroditism, and vice versa.
The nematodes, roundworms or eelworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments. Most species are free-living, feeding on microorganisms, but there are many that are parasitic. The parasitic worms (helminths) are the cause of soil-transmitted helminthiases.
Bursaphelenchus is a genus of nematodes (roundworms) in the order Aphelenchida. Most are obligate mycophages, but some feed on wood, with two species, the red ring nematode and the pine wood nematode, economically significant as pests of coconut palms and of pine trees, respectively. Given that Bursaphelenchus species are usually hard to distinguish from one another except by trained nematologists with access to microscopes or DNA sequence analysis, the entire genus is put under quarantine in some countries. Where this is not the case however, these nematodes are becoming established as model organisms for nematode developmental biology, ecology and genetics.
The Rhabditidae are a family of nematodes which includes the model organism Caenorhabditis elegans.
Caenorhabditis japonica is a species of nematodes in the genus Caenorhabditis. Its genome was sequenced by the McDonnell Genome Institute at Washington University School of Medicine. This gonochoristic species is found in the 'Japonica' group, the sister clade to the 'Elegans' group, in the 'Elegans' supergroup.
Micoletzkya is a genus of predatory bark-beetle-associated nematodes in the family Diplogastridae. The genus was named for the Austrian nematologist Heinrich Micoletzky. As of 2013 it consists of 25 described species.
Diplogastridae, formerly Diplogasteridae, are a family of nematodes (roundworms) known from a wide range of habitats, often in commensal or parasitic associations with insects.
Pristionchus is a genus of nematodes (roundworms) in the family Diplogastridae that currently includes more than 50 described species. They are known mainly as non-parasitic associates of insects, especially beetles, while others have been reported from soil, organic matter, or rotting wood. The genus includes P. pacificus, a satellite model organism to the well-studied nematode Caenorhabditis elegans.
Sudhausia is a genus of nematodes (roundworms) of the family Diplogastridae. They live in association with dung beetles and are primarily known from Africa. Species of Sudhausia show a suite of biological features that, together, are unusual for nematodes and animals in general: hermaphrodites, which are females in form, mature to produce offspring before they are adults and thus even capable of mating, and their eggs grow in size during development. Hermaphrodites are also always live-bearing, which is unusual for nematodes under non-stressful conditions. The genus is named in honor of Walter Sudhaus, a German nematologist.
Levipalatum texanum is a free-living nematode (roundworm) in the family Diplogastridae. The species is androdioecious, consisting of self-fertile hermaphrodites which are morphologically females, and males. It is known from the south-eastern United States and has been found to live in association with scarab beetles, although it has also been baited from soil. Nematodes of this species can be cultured on bacterium Escherichia coli in the laboratory, and they are presumed to also feed on microorganisms in the wild. Levipalatum is a monotypic genus.
Caenorhabditis angaria is a small nematode, in the same genus as the model organism Caenorhabditis elegans. The name is from the Latin after the tendency to ride weevils. Prior to 2011, the species was referred to as C. sp. 2, C. sp. 3, and C. sp. PS1010. Its genome was sequenced at the California Institute of Technology in 2010. This species is gonochoristic. It has distinct morphology and behavior compared to C. elegans; notably, C. angaria males exhibit a spiral mating behavior. Its divergence from C. elegans is similar to the distance between humans and fish. C. castelli is its closest relative, and the two species can produce F1 hybrids.
Parastrachia japonensis is a species of true bugs belonging to the family Parastrachiidae. It is one of the two species in the genus, both from Eastern Asia.
Oscheius is a genus of nematode.
Allodiplogaster sudhausi is a free-living nematode species in the Diplogastridae family. It was described in 2008 as Koerneria sudhausi, before being moved to the genus Allodiplogaster in 2014. A. sudhausi is omnivorous. It predates on other nematodes, but can be cultured on Escherichia coli OP50 bacterium on agar.
István Andrássy was a Hungarian nematologist. Starting with his first publication in 1952 on the nematode fauna of Mount Bükk, over his dissertation in 1973 on the evolution of nematodes to his last days he was a very prolific scientist, publishing more than 200 manuscripts, chapters and books on the class of Nematoda. He described 530 taxa of nematodes and at least 60 nematode taxa are named after him, which shows the huge respect he had in the nematologists world.
Mononchoides is a genus of nematodes belonging to the family Diplogastridae.
