Abstract A new species of genus Bychowslcyella Achmerow 1952 is described fromthe gills of attu (Family: )from Hindon River Ghaziabad. It is the /irst report of this genus from Hindon River. The present specimen dffirs from all the known species in the structure of dorsal anchor which is 'boreal type'in the present specimen. Ventral anchor in the present specimen is 'boreal' type whereos ventral anchor is 'nanus type'in Bychowskyella asiatico (Jain, 1959) Gussev, 1961, 'Pterocleidus type'with a prominent clamping formotion in Bychowskyella gomtia (Jain, i,959) Gussev, 1961, Bychowskyella indica (Jain, 1959) Gussev, 1961, Bychowslcyella gharui (Tripathi, 1959) Gussey, 1961, whereas ventral anchor is 'juvenile type'in Bychowskyella wallagonia (Jain, 1959) Gusseu 1961, Bychowslcyella vacha (Tripathi, 1959) Gussev, 1961, Bychowskyella bychowskii Gussev, 1977, Bychowskyella chauhani Yenkatanarasaiah, 1989, Bychowslcyella raipurensis Majumdar and Agrawal, 1989, Bychowskyella fossilisi Majumdar and Agrawal, 1989, Bychowskyella jaini Agrawal, et. al., 1996. The ventral transverse bar is different from all the above species in its structure. The onchium is absent in Bychowskyella wallagonia (Jain, 1959) Gussev, 1961 and Bychowskyella indica (Jain, 1959) Gusseu, 1961. It is a vqriation of broad triangular heart shaped to leaf like structure in rest of the species except Bychowslcyella asiotica (Jain, 1959) Gusseu 1961. The onchium of B. asciatica (Jain, 1959) Gussev 196I is rod like. But in the present specimen, onchium bears three finger like projections towords its posterior end. On the basis of above variations the present specimen is described as new species Byc how s lcy e I I a hindon i. Keywords: Monogeneans, BychowslryeUa hindoni.
