:[3] Pupillinae W. Turton, 1831 and Pupoidinae Iredale, 1940.

[5] The type genus, Pupilla, in direct contrast, has numerous living and extinct species found in Europe, Northern Africa, North America and South-East Asia.

[citation needed] In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).
