The present discussion deals with the study of Genus Senga wakadii sp. nov. collected from freshwater fish Mastacembelus armatus at. Wakadi dam, Dist Parbhani (M.S.) India. The present cestode parasite’s character comes closer to the earlier known species of Genus Senga but also having some differentiating remarkable characters. Scolex is vessel shaped with two bothria, the inner portion of bothridia is convoluted, overlapped internally in the middle, and extends up to the posterior part of the scolex. Rostellar hooks are arranged in a circular manner, rostellar hooks are 30-35 in numbers. Mature segment two to three times broader than long, testes 55-65 in number, the cirrus is a thin tube, within the cirrus pouch. Vas deferens is a thin slightly curved. The vagina arises from the posterior side of the cirrus pouch as a short narrow tube. Ovary large, bilobed, located at the posterior side of the segment, Uterus starts from ootype, median, balloon-shaped, and vitellaria are granular
