Mesohedenstroemia is a genus of ammonites. It was described by Chao in 1959, who described three species; M. kwangsiana (the type species), M. inflata Chao, 1959, and M. planata, from the Triassic of what is now China. A new species, M. olgae, was described from the Olenekian of Russia by Yuri D. Zakharov and Nasrin Mousavi Abnavi in 2012, and was named in honour of Olga P. Smyshyaeva.[2]
