During a survey on species diversity of trichodinid ciliates from freshwater fishes in the Baikka Beel of Moulvibazar district in Sylhet division from January to December 2015, two species of ciliates were identified, of which one is new to science. Trichodina hoffmani Wellborn, 1967 is collected from the gills of Mystus tengara, and Trichodina amblypharyngodoni sp. n. is described from Amblypharyngodon mola using the silver nitrate impregnation method. T. amblypharyngodoni sp. n. is characterized by having a large, darkly stained central area; rectangularly-rounded butterspoon-shaped blade with very narrow interblade space and blunt tangent point; indistinct anterior and posterior blade apophysis, but a rounded apex near the base of the central part of denticle; slender, sometimes slightly triangular central part with rounded tip; and filamentous, curved, anteriorly directed rays with inflated tip and indistinct central groove. Based on these characters and the unique shape and absence of variability of the denticles among the silver impregnated specimens of the present species, it may be said that to a lesser extent, it resembles Trichodina prowazeki Grupcheva and Lom, 1980.
