Some ammonites of the subfamily Garantianinae are revised based on the study of new collections from the lower part of the upper Subformation of the Djangura Formation (Upper Bajocian Strenoceras niortense Chronozone, Middle Jurassic) near the village of Krasnogorskaya on the Kuban River (Russia, Karachay-Cherkessia). The dimorph pair Strenoceras acre [m]/Orthogarantiana humilis [M], taxa, originally described as Cosmoceras subfurcatum var. acre Zatwornitzky, 1914 and Reineckeia? humilis Zatwornitzky, 1914, are discussed.
