Taxonomy
Myonia (Myonia) bulkurensis was named by Astafieva-Urbajtis (1976). Its type specimen is VNIGRf Museum 804-1, a valve (Left valve), and it is a 3D body fossil. Its type locality is Left bank Lena River, above mouth of Bulkur River, which is in a Capitanian marine siliciclastic in the Dulgalakh Formation of the Russian Federation.

It was synonymized subjectively with Myonia (Myonia) carinata by Muromtseva and Guskov (1984); it was recombined as Pachymyonia bulkurensis by Biakov (2007).
