The genus Pallisentis is revised. Golvan's 3 subgenera (Farzandia, Neosentis, Pallisentis) were distinguished solely by the number of hooks in proboscis hook circles, which proved to be a variable trait. Three new subgenera are erected based on the relative size of hooks in subsequent circles, the size of cement glands, and the number of their giant nuclei. A new species of Pallisentis is described from the snake head mullet, Ophicephalus maculatus, in Vietnam. A key to all 26 species of the genus Pallisentis accepted as valid and following our classification is included. A new quadrigyrid genus Pararaosentis is erected.
