Quadrigyridae is the only family within Gyracanthocephala, an order of parasitic worms of class Eoacanthocephala. This family contains two subfamilies, ten genera and about 92 species.
Species in Quadrigyridae are divided into two subfamilies: Pallisentinae Van Cleave, 1928 with five genera and Quadrigyrinae Van Cleave, 1920 with three.[a]
Acanthogyrus Thapar, 1927
Golvan in 1959 divided the genus Acanthogyrus into two subgenera: Acanthogyrus and Acanthosentis based on the number of proboscis hooks; there are 18 (3 circles of 6 hooks each) in Acanthosentis and 24 (3 circles of 8 hooks each) in Acanthogyrus.
Acanthogyrus (Acanthogyrus) Thapar, 1927
Found in the intestine of a rohu (Labeo rohita) in Lucknow, and from the intestines of a catla (Catla catla) from Kolkata, both in India.
Acanthogyrus (Acanthosentis) Verma and Datta, 1929
A. barmeshoori was found infesting Aphanius farsicus in Maharlou Lake, Fars Province, Iran.[1]
Palliolisentis Machado-Filho, 1960
Pallisentis Van Cleave, 1928[b]
P. singaporensis has 8 to 12 proboscis hooks per circle, gradually declining in size posteriorly. They measure from the anterior are 62 to 64, 49 to 54, 36 to 46 and 24 to 28 um long. The trunk spines are conical and do not extend to the posterior end in 25 or 26 circles, each with 10 spines. In the male, the cement gland is long and has 23 to 25 giant nuclei and lack Saefftigen's pouch. They have unequal lemnisci. The female gonopore is terminal.[3]

Acanthodelta Diaz-Ungria and Gracia-Rodrigo, 1958
Machadosentis Noronha, 1992
Quadrigyrus Van Cleave, 1920
Q. nickoli was found infesting Hoplerythrinus unitaeniatus from Colombia. It has four circular rows of between 23 and 29 trunk spines each with heavy dendritic roots. The species name nickoli is named after Dr. Brent B. Nickol, a parasitologist from the University of Nebraska.[4]
Q. torquatus has been found infesting the intestines of Ageneiosus caucanus and Hoplias malabaricus in the Magdalena River basin in Colombia.[5] It was also found in Hoplerythrinus unitaeniatus also from Colombia.[4]
Quadrigyridae species parasitize fish.
The catla is a host of Acanthogyrus acanthogyrus

Les Quadrigyridae sont une famille de vers parasites de l'embranchement des acanthocéphales (vers à tête épineuse). Les acanthocéphales sont de petits animaux vermiformes parasites de vertébrés dont la taille varie entre 1 mm et 70 cm. Ils sont caractérisés par un proboscis rétractable portant des épines courbées en arrière qui leur permet de s'accrocher à la paroi intestinale de leurs hôtes.
