Diagnosis.
Shell with a complex gas exchange system consisting of a common external sutural tube and several extremely narrow, perpendicularly running microtunnels, formed by the outermost shell layer (
Pall-Gergely
et al. 2016
). Bursa copulatrix connecting to lateral side of ovarium.
Remarks.
In the past this group has been treated as a subfamily of the
Cyclophoridae
, and as a family of its own right. The complex gas exchange system, combined with the unique position of the bursa copulatrix (both are important synapomorphic characters), seems to justify the distinction of this group as an independent family.
