Abstract
Nematehelminthic examination of two species of freshwater fishes, Mastacembelus armatus and Oreochromis niloticus collected from the Indus river of Sindh Pakistan, revealed presence of subgenus Spirocamallanus of genus Procamallanus. The subgenus was characterized by the presence of spiral thickening in buccal capsule. The prevalence of subgenus was higher in Mastacembelus armatus (33.33%) than Oreochromis niloticus (7.69%). There is difference of mean intensity (3.66 and 4) and density (1.2 and 0.306) of Sprirocamallanus in both fishes. This subgenus is recorded for first time in Mastacembelus armatus and Oreochromis niloticus from the lower Indus river in Sindh province of Pakistan.
