My specimen of Cristaria herculea (Middendorff, 1848) is from the Amur
River system in Russia. Zhadin (1952), in his review of the freshwater
molluscs of the USSR, synonymizes herculea with Cristaria plicata (Leach,
1815) and gives the range of the latter as the Amur basin - a large area
of China and the former USSR. It is probably the largest unionid in the
world but not the most massive. That title probably resides with the North
American Megalonaias nervosa.
Images of plicata may be found in the mussel gallery in our Division
website (see address below).
