Identification
Members of Coptotominae can be distinguished from other Dytiscidae by their placement in the Coptotomus. Identification to subfamily level requires recognition of the genus Coptotomus, which has been defined by morphological characters separating it from other dytiscid genera. The subfamily lacks the derived features characteristic of other Dytiscidae subfamilies such as Cybistrinae or Dytiscinae.
