In a 1978 description of Bicirronema as a member of the family Chambersiellidae, Andrassy, 1978 proposed the following structure:

Fam. Chambersiellidae Thorne, 1937

      Subfam. Chambersiellinae Thorne, 1937

           Chambersiella Cobb, 1920

           Geraldius Sanwal, 1971

     Subfam. Bicirronematinae n. subfam. (Later elevated to family level by DeLey, 1997)

           Bicirronema n. gen.

      Subfam. Macrolaiminae Sanwal, 1971

           Diastolaimus Rahm, 1928 Syn. Santafea Massey, 1963 ï

           Macrolaimellus Andrassy, 1966

           Macrolainus Maupas, 1900 Syn. Seleneella Rahm, 1932

By 1997, De Ley had elevated the subfamily Bicirronematinae to family level: Bicirronematidae.

The Chambersiellidae and Bicirronematidae history seems to go like this:

• Rahm, 1928 described Diastolaimus papillatus

• Goodey, 1951 synonymized Diastolaimus with Macrolaimus so it became Macrolaimus papillatus

• Thorne, 1937 established Chambersiellinae as a subfamily of Cephalobidae.

• Sanwal, 1957 removed Chambersiellinae from Cephalobidae and elevated it to Chambersiellidae

• Sanwal. 1957 separated Diastolaimus from Macrolaimus and transferred Diastolaimus to Chambersiellidae

• Massey, 1963 added Santafea and Macrolaimus to Chambersiellidae

• Sanwal 1971 transferred Chambersiella  bakeri to a new genus Geraldius

• Sanwal, 1971 grouped Chambersilella, Geraldius, Santafea and Diastolaimus into the Chambersiellinae based on the shape and structure of the stoma and Macrolaimis to the Macrolaiminae

• Andrassy, 1978 created Bicirronematidae as a subfamily of Chambersiellidae and included Bicirronema. Tricirronema and Trualaimus

• De Ley 1997 elevated Bicorronematinae to Bicrirronematidae
