The following three subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005)

:

• † Procerithiinae Cossmann, 1906
• † Paracerithiinae Cossmann, 1906
• Cryptaulacinae Gründel, 1976 - include Argyropeza

2006 taxonomy

Bandel (2006) have described a new subfamily Argyropezinae.

• Argyropezinae Bandel, 2006
• † Procerithiinae Cossmann, 1906 - include Cryptaulax
• † Paracerithiinae Cossmann, 1906

Bandel (2006) have shown doubts about validity of Cryptaulacinae, because Cryptaulax and Procerithium may be based on the same species.
