摘要

Eight species of the genus Gogorevia (Bacillariophyta) are reported from across China, of which five have been previously described and three of them, namely Gogorevia ellipticum sp. nov., Gogorevia rectangularis sp. nov., and Gogorevia subconstricta sp. nov., are new to science. The three new species are descripted in morphology with light and scanning electron microscope and compared with other closely related species of Gogorevia. Specifically, G. ellipticum sp. nov. has an elliptical valve with subrostrate or capitate apices. G. rectangularis sp. nov. has an elongated and rectangular valve with rostrate apices, parallel and slightly constricted at the center margins. G. subconstricta sp. nov. has a linear-elliptical valve with clearly undulate margins that are constricted in the center, protracted and distinctly capitate apices. This study enriched our knowledge on the species diversity and geographical distribution of Gogorevia in the world.
