Mammitinae comprises a subfamily within the Acanthoceratidae (Ammonoidea) characterized by moderately to very evolute shells with rectangular to squarish whorl sections along with blunt umbilical and prominent inner and outer ventrolateral tubercles on sparse ribs that may be round and strong, sharp and narrow, or absent. The suture is somewhat simpler than that of the Acanthoceratinae. Range is restricted to the lower Turonian stage of the Upper Cretaceous.

Genera include:

Mammites Laube & Bruden, 1886Benueites Reyment 1954Metasigaloceras Hyatt, 1903Pseudoaspidoceras Hyatt, 1903Watinoceras Warren,1930

The inclusion of Kamerunoceras Reyment, 1940, is doubtful.
