Gigantorhynchida is an order containing a single family, Gigantorhynchidae[1] of parasitic worms that attach themselves to the intestinal wall of terrestrial vertebrates. Gigantorhynchida contains the following three genera:[2]

The genus Gigantorhynchus is characterized by the presence of a cylindrical proboscis with a crown of robust hooks at the apex followed by numerous small hooks on the rest of the proboscis.[3][4] The body, or trunk, is long with pseudosegmentation, the lemnisci are filiform, and the testes are ellipsoid.[3] Species of Gigantorhynchus are distinguished based on the number and size of hooks on the crown of the proboscis, the type of pseudosegmentation, and size of the ellipsoid eggs.[3] Males of all species possess eight cement glands which are used to temporarily close the posterior end of the female after copulation.[5] There is pronounced sexual dimorphism with the female often two or more times longer than the male.[3]
There is one species, Intraproboscis sanghae in this genus. It was found infesting the African black-bellied pangolin (Phataginus tetradactyla) in the Central African Republic.[6]

Taxonomy

Шаблон:CladogramPhylogenetically, the family Gigantorhynchidae is sister to the family Moniliformidae, represented by sequences of Moniliformis Moniliformis that form a supported monophyletic group. The group formed by Gigantorhynchidae and Moniliformidae suggest it to be a sister to the group formed by sequences of Macracanthorhynchus ingens and Oncicola venezuelensis[3]
