Description of three new species of the genusMyxobolusinfecting carp fishes of India.
MyxobolusBütschli, 1882 (Myxozoa, Myxosporea, Bivalvulida, Myxobolidae) is an important parasitic protozoan of freshwater fishes reported from almost all over the world. The severity of infection may lead to mortality of the host fish. The present paper deals with the description of three new species ofMyxobolusBütschli, 1882,Myxobolus sonarpurensissp. nov.,Myxobolus elongatumsp. nov. andMyxobolus petalumsp. nov. from a freshwater minor carpLabeo bata(Hamilton, 1822) and major carpLabeo rohita(Hamilton, 1822) respectively from West Bengal, India. Spores ofMyxobolus sonarpurensissp. nov. measures 12.16 µm × 6.74 µm, with two elongated unequal sized polar capsules measuring, 8.84 µm × 3.019 µm and 7.71 µm × 3.12 µm. Spores ofMyxobolus elongatumsp. nov. are 16.23 µm × 7.9 µm with two equal polar capsules 8.896 µm × 3.468 µm and 6.51 µm × 3.46 µm. In comparison to aforementioned two new species,Myxoboluspetalumsp. nov. have two equal polar capsules, 7.905 µm × 2.975 µm (2.9 µm) in each spore, 12.07 µm × 5.95 µm.
