Male: Caudal alae wide anteriorly, diminish in width at about middle of tail; ten pairs of caudal papillae, paracloacal group five pairs-three lateral, two subventral; of lateral papillae, the anterior on each side is very large, with stout granular base, the next is smaller with thickened base, while posterior is long but comparatively slender; posterior group situated on more slender portion of tail, consists of three pairs, of which the anterior papilla most slender and middle papilla stoutest; spicules sub equal, flattened, gradually tapering, longitudinally striated.
H. spumosa is a cosmopolitan parasite, commonly reported from the caecum of rats worldwide. In India this specieshas been reported from Rattus norvegicus from Behrampore, West Bengal. Niphadkar (1977) reported it from B. bengalensis, R. rattus and R. norvegicus from two localities of Bombay and Balachandra and Ranade (1978), from R. rattus and B. indica from Poona city.
The present study gives the first report of the occurrence of the H. spumosa from Mizoram Northeast India and R. nitidus, B. mackenziei are its new host records.
