Light and scanning electron microscopy (SEM) revealed similarities and differences in the glochidia of four species belonging to two unionid genera from Primorye Territory in Far Eastern Russia: Cristaria herculea, Cristaria tuberculata, Sinanodonta amurensis, and Sinanodonta likharevi. Glochidia of the two species of Cristaria Schumacher, 1817 differed from each other in morphological details of the hook (hook length, maximum height of hook microstylets) and hinge, but not in shape (height/length ratio) or size. Glochidia of the two species of Sinanodonta Modell, 1945 differed from each other in quantitative features such as height, length of hinge, and shape (height/ length ratio). Glochidia of these two species of Sinanodonta lacked some characters possessed by other genera in the tribe Anodontini, in which Sinanodonta has been classified, and shared some characters with the two species of Cristaria, which are classified in the tribe Limnoscaphini, raising uncertainty about the correct classification of Sinanodonta.
