Leptosomatidae is a family of benthic marine nematode worms.
The Trichocephalida is an order of parasitic nematodes.
Enoplea (enopleans) is a class, which with the classes Secernentea and Chromadorea make up the phylum Nematoda in current taxonomy. The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
Secernentea was a class of nematodes in the Classical Phylogeny System and is no longer in use. This morphological-based classification system has been replaced by the Modern Phylogeny system, where taxonomy assignment is based on small subunit ribosomal DNA.
Dorylaimida (dorylaims) is a diverse order of nematodes with both soil and freshwater species.
Anguina is a genus of plant pathogenic nematodes.
Subclass Spiruria comprises mostly parasitic secernentean nematodes. In an alternate classification, they are treated as suborder Spirurina, with the orders listed here being ranked as infraorders.
The nematodesroundworms 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.
Enoplida is an order of nematodes. It is one of two orders in Enoplia, which is one of two subclasses in Class Enoplea.
Dorylaimia is a subclass of nematodes.
Aphelenchoididea is a nematode superfamily in the order Rhabditida. Its members can be found inside bodies of species from the families Lepidoptera and Blattodea.
The Enoplia are a subclass of nematodes in the class Enoplea.
Paratrichodorus is a genus of terrestrial root feeding (stubby-root) nematodes in the Trichodoridae family (trichorids), being one of five genera. They are economically important plant parasites and virus vectors. The females are didelphic, and are distributed worldwide.
Triplonchida is an order of terrestrial nematodes, and is one of two orders making up the subclass Enoplia.
Diphtherophorina is a suborder of terrestrial nematodes, being one of three that constitute suborder Triplonchida.
Trichodoridae is a family of terrestrial root feeding nematodes, being one of two that constitute suborder Triplonchida. They are economically important plant parasites and virus vectors.
Trichodorus is a genus of terrestrial root feeding (stubby-root) nematodes in the Trichodoridae family (trichorids), being one of five genera. They are economically important plant parasites and virus vectors.
Protorhabditis is a genus of nematodes in the family Rhabditidae.
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.
