Trichuridae
The roundworm family Trichuridae includes the type genus Trichuris and some less widely known members. They are placed in subclass Dorylaimia of the class Enoplea; however, the former might be better treated as a class in its own right. That nonwithstanding, their order has been known under alternate names in the past, namely Trichiurida.
The genus Trichuris is particularly well known for being a common parasite of domestic animals and less usually humans. Its common name "whipworm" refers to the shape of these worms; they look like whips with wider "handles" at the posterior end.
The genera of Trichuridae are:Capillostrongyloides Freitas & Lent, 1935Orthothominx Teixeira de Freitas & Jorge da Silva, 1960Pearsonema Teixeira de Freitas & Machado de Mendonça, 1960Sclerotrichum Rudolphi, 1819Tenoranema Mas-Coma & Esteban, 1985Trichuris Roederer, 1761
Some authors consider Capillarinae to be a subfamily of Trichuridae.
