Species in Quadrigyridae are divided into two subfamilies: Pallisentinae Van Cleave, 1928 with five genera and Quadrigyrinae Van Cleave, 1920 with three.[a]
Golvan in 1959 divided the genus Acanthogyrus Thapar, 1927 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.[citation needed]
