Overview of the extant genera of the Butidae with number of species, zoogeographic distribution and habitats (after [7], [49], [52], [55]) and selected morphological differences that separate them from †Lepidocottus.

Note that Odonteleotris, Parviparma and Pogoneleotris are not listed among the valid genera of Butidae in [21]; their systematic affinities are in need of further investigation. n.a. = data not available.
