Ernoporus Thomson, 1859

Diagnosis. This genus can be distinguished from all other North American genera by the combination of the eye, which is entire, with its center slightly below level of the antennae, and the concentric rows of asperities on the pronotum. Some Pseudothysanoes Blackman, 1920 (Micracidini) are superficially similar but do not have concentric rows of asperities, and the center of the eye is above the level of the antennae. Trypolepis Bright, 2019 (Corthylini) , a monotypic genus from the Caribbean, is somewhat similar based on the small size, concentric asperities and abundant scale-like setae, but has a broadly emarginated eye. Several Pityophthorus Eichhoff, 1864 (Corthylini) have concentric asperities, but also have an emarginated eye.
