Comments. This species was not recorded from Canada, but it is most likely transcontinental in the north. An isolated population of this species is known from Mt. Washington in NH ( Bernhauer 1907). Oxypoda robusticornis is similar to O. leechi but differs from it by its broader body, less transverse pronotum, thicker antennae with more transverse apical antennomeres; the median lobe of aedeagus is very similar in the two species ( Klimaszewski et al. 2021).
