Abstract: This paper deals with a new species and a new record of genus of Myxosporidian parasite from freshwater fish Zhejiang Province. Measurements are in microns. Type speciemens are deposited in the Department of Biology, Hangzhou University.Trigonosporous zhejiangensis sp. nov. (fig. 1)Host: Synechogobius ommaturus (Richardson)Location: Membranes of gill arch bone.Locality: Yuyao of Zhejiang (30°5'N, 121°10'E).Cyst: White, round or roundish form.Spore: Nearly isosceles triangular in front view, spindle form in top and sutural view. The anterior end is rounded, the base is convex. Two equal pyriform polar capsules arranged at the anterior end of the spore. The sporoplasm contains an iodinophile vacuole, two sporopla-sinic nuclei and two capsular nuclei are observed.Dimension of preserved (in 4% formalin) spores: Length 9.31(8.84-10.31), width 14.7 (13.26-16.21), thickness 4.22(3.68-4.79), polar capsule 3.66(3.32-4.05) by 2.25(2.06-2.58); length of extended filament 35.36(25.79-47.89), length of transversal filaments 31.38(29.94-33.15), diameter of iodinophile vacuole 2.82(2.21-3.32).This new species is similar to Trigonos porous aconthogobii Hoshina, 1952 but differs from the latter in size and shape of spores.
