The bryocorine genus Caulotops Bergroth (Miridae: Eccritotarsini), originally described to acccommodate its only species C. puncticollis Bergroth, is shown not to be congeneric with all other species now included in the genus from North, Central, and northern South America. Consequently, four new genera are established for the following 18 species, including five new combinations and 12 species described as new: Agaveocoris n. gen. for Caulotops agavis Reuter (as the type species) n. comb., C. barberi n. comb., and C. distanti Reuter n. comb. and the new species A. bimaculatus n. sp., A. barrerai n. sp., A. dimidiatus n. sp., A. roseus n. sp., A. rostratus n. sp., A. schaffneri n. sp., and A. scutellatus n. sp; Laterospinocoris n. gen. for Caulotops cyaneipennis Reuter, new comb. (as the type species) and the new species L. mexicanus n. sp.; Nigrotomocoris n. gen. for Caulotops nigrus (as the type species) n. comb., C. tibiopallidus Carvalho n. comb., and the new species N. longirostris n. sp.; and Schaffnerocoris n. gen., for S. fuscotibialis n. sp. (as the type species), S. pallipes n. sp., and S. similis n. sp. Each species is diagnosed and described; habitus images, illustration of male genitalia, and a key to species are provided; and host use and the unique genitalic systems of these taxa are discussed. A phylogenetic analysis, based on 22 taxa and 39 characters, resulted in three trees supporting the monophyly of the four new genera proposed in this study.
