Cryptodifflugiidae Explained

Cryptodifflugiidae is a family of arcellinid testate amoebae.^[1]

Description

Members of this family are conopodous (with conical pseudopods) amoebae with the body in a clear, usually firm, vase-shaped test, and conical pseudopods for locomotion that extend separately from the opening of the test.^[2]

Classification

The classification of the family, as of 2019:^[1]

• Infraorder Phryganellina Bovee 1985
  • Family Cryptodifflugiidae Penard 1890
    • Cryptodifflugia Cash 1904 – 23 species^[3]
    • Meisterfeldia Bobrov 2016 – 6 species^{[4] [5]}
    • Wailesella Deflandre 1928 – 1 species^[6]

The 2022 classification places Meisterfeldia and Wailesella as Arcellinida incertae sedis, leaving Cryptodifflugia as the sole member of the family.^[7]
