Summary:Small intestine No. of fish examined: 50 No. of worms recovered: 10 males and 2 females from a single fish Description Neoechinorhynchidae; with characters of the genus Neoechinorhynchus Stiles and Hassall, 1905. Neck 0.015-0.023.Proboscis receptacle 0.40-0.46 by 0.21-0.24.Length of reproductive system from the genital pore to the uterine bell 0.92-1.20.Size of eggs 0.015-0.024 by 0.012-0.016. Discussion The morphological characteristics of the specimens from marine fish (Mugilcephalus Linn., 1758) which include shape and size of the proboscis, the number and position of proboscis hooks clearly differentiates it from other species within the genus Neoechinorhynchus. The present specimens differs from N. buckneri Amin and Heckmann, 2009 which have separated testes, from N. carinatus Buckner and Buckner, 1993 which have eggs with polar prolongations from N. cristatus Lynch, 1936 which have short and robust body, from N. prolixoides Bullock, 1963 which have smaller anterior most hooks; from N. carassii Roitman, 1961 which have anterior hooks three times as long as middle hooks and from N. prolixus Van Cleave and Timmons, 1952 with female having 2 integumentary lobes on either size of genital pore.
