Family of roundworms
Capillariidae is a family of parasitic nematodes. All its members are parasites in vertebrates when they are in their adult stage.
Taxonomy.
The family Capillariidae was created by Railliet in 1915. It is accepted in the most recent classifications of the Nematoda, in which it is one of the members of the order Trichocephalida. However, "Capillaria" and closely related genera are sometimes included in the family Trichinellidae in other classifications.
The taxonomy of the Capillariidae is disputed: according to different classifications, the family includes the single genus Capillaria or 22 different genera ("Amphibiocapillaria, Aonchotheca, Baruscapillaria, Calodium, Capillaria, Capillostrongyloides, Crocodylocapillaria, Echinocoleus, Eucoleus, Freitascapillaria, Gessyella, Liniscus, Paracapillaria, Paracapillaroides, Pearsonema, Paratrichosoma, Pseudocapillaria, Piscicapillaria, Pseudocapillaroides, Pterothominx, Schulmanela", and "Tenoranema"). In 2017, a new genus was added to this list: "Lobocapillaria". Old literature, and sometimes modern medical literature, use "Capillaria" as a genus for species included in all these genera. In contrast, certain species parasitic in fish, previously classified in "Capillaria", are now considered members of the genus "Huffmanela" (family Trichosomoididae).
The term Capillariasis is generally used for diseases produced by species of "Capillaria", even if the species is now placed in another genus.
