Elonus hesperus Werner, 1990 : Werner, 1990: 229, Werner, 1992. ♂ holotype: USNM [examined, dissected, remounted]

Type locality. United States, Oklahoma, Latimer County.

Distribution. Mexico, United States (Arizona, Missouri, Oklahoma).

Notes. This species shows morphological affinities with E. gruberi n. sp., from which it is best separated by the dense whitish pubescence covering the elytra (absent in E. gruberi n. sp.), by its lighter color (brown vs. dark in E. gruberi n. sp.), and by the shape and size of the orange elytral marking (broad in E. hesperus , but notched or most often interrupted in E. gruberi n. sp.).
