Acriclymenia is a clymeniid ammonite with a sharp rimmed (oxyconic), lenticular shell, named by Bogoslovsky in 1975. As with other clymeniids, Acriclymenia has a dorsal siphuncle that runs along the inner, concave, rim of the whorls. The venter, or outer rim, is keeled with associated longitudinal grooves. Acriclymenia maybe junior synonym of Carinoclymenia.
