Information on the distribution of large bivalves of the genus Middendorffinaia in Primorsky Krai has been clarified. Both species of the genus are listed in the Red Data Book of the Russian Federation: Middendorffinaia mongolica (Middendorff, 1851) and M. sujfunensis Moskvicheva et Starobogatov, 1973. Currently known populations of these species are listed, along with an assessment of their condition. A reduction in the number and area of distribution of the species is demonstrated. The main threats and ways for the Middendorffinaia species conservation in Primorsky Krai are discussed.
