The cestode Vermaia pseudotropii, a parasite of the catfish Clupisoma garua in India and the only known hyperapolytic proteocephalidean, is redescribed based on freshly collected material from the type-host from West Bengal, India. Surface structures, including giant coniform spinitriches on the rostellum-like organ, are described for the first time using SEM and new morphological data on the rostellum-like organ and its armature, terminal genitalia, uterine development, longitudinal internal musculature and egg morphology are provided. The validity of the genus Vermaia is also confirmed and its species are reviewed. Gangesia sumani is synonymized with V. pseudotropii. The present study revealed conspecificity of Gangesia (Vermaia) jammuensis with Gangesia agraensis. Vermaia sorrakowahi differs from V. pseudotropii in the distribution of vitelline follicles, the pre-ecuatorial position of the cirrus-sac, number and size of hooks on the rostellum-like organ, and number of testes.
