Abstract

Light and scanning electron microscope observations of Cymbella sagarensis Gandhi are presented. Morphological peculiarities of this species show that it belongs to the genus Oricymba Jüttner, Krammer, Cox, Van de Vijver & Tuji. Based on our observations, the new taxonomic combination, Oricymba sagarensis (Gandhi) C.Radhakrishnan, Kociolek & B.Karthick, comb. nov. is proposed. Morphological comparison of this species with other known members of Oricymba is given. A second taxon described by Gandhi, C. sagarensis f. gracilis Gandhi, is suggested to be a synonym of the nominate forma. Distribution of this species and other Oricymba taxa is discussed.
