abstract
A new trematode C. aliraazi n. sp. is described from the gall bladder of A. tristis of District Larkana, Sindh, Pakistan. In all, 03 trematodes; one new species C. aliraazi was recorded. The present trematode differs from its allies in the body shape; size; presence of sub-terminal oral sucker; wider ventral sucker; position of testes and distribution of uterus. On the basis of such morpho-metrical diversification, the new species C. aliraazi has been proposed. The authoress dedicates new species in the honour and name of her elder brother Mr. Ali Raza Soomro.
