Abstract
During the survey of freshwater fish Wallago attu, severe infection of known myxosporean species, Thelohanellus batae Lalitha kumari,1969 belonging to genus Thelohellnus Kudo, 1933 parasitizing gill filaments was found from Meerut District (UP), India. This species was described on the basis of morphology of plasmodia, histology findings on locations of plasmodia and DNA sequence data. Plasmodia of T. wallogoi are characterized in having spores measuring 11.8 to 6.7 µm, pyriform in valvular view and lenticular in sutural view having anterior end pointed and posterior end rounded with shell valves. Mature plasmodia are histozoic with single polar capsule measuring 7.2 to 3.0 µm, having polar filaments of 18 µm with 4 to 5 coilings. Histology reveal no pathological changes but severe infections. SEM revealed flat surface. Supplemented 18S rRNA gene sequence of T. batae did not show a close relationship with any other Thelohanellus spp., represented in gene bank.
