  • tribe † Helicocryptini Cox, 1960

2008 taxonomy

Colloniidae was elevated to family level and (together with Phasianellidae) belongs to superfamily Phasianelloidea according to Williams et al. (2008).^[1] McLean (2012) added two more subfamilies Liotipomatinae and Moelleriinae.^[2]

It contains the following subfamilies:
