Burkenroad, 1963
Infraorders treated:
infraorder Heterotremata Guinot, 1977
infraorder Podotremata Guinot, 1977
infraorder Thoracotremata Guinot, 1977
Note: The polyphyletic nature of the Podotremata may be subject to debate. Generally all 'true crabs' are now considered to belong to the single infraorder Brachyura (see Martin & Davis, 2001, Appendix I: Comments and Opinions).
