Lamtopyxis callistoma – after Bonnet (1974)

Family Lamtopyxidae Bonnet, 1974

Diagnosis: Test with flat sole, bilaterally symmetrical due to its elliptical internal opening at the end of a deeply invaginated tube; the external aperture is bordered by large teeth.
This family is believed to be intermediate between Cyclopyxis and Distomatopyxis (Bonnet, 1979a).
