The American thick-knees have been found to comprise an ancient lineage basal to other burhinids (Černý and Natale 2022), and have thus been given a new genus name, Hesperoburhinus Černý et al., 2023. Thus, the Double-striped Thick-knee Burhinus bistriatus becomes Hesperoburhinus bistriatus and Peruvian Thick-knee Burhinus superciliaris becomes Hesperoburhinus superciliaris (https://www.museum.lsu.edu/~Remsen/SACCprop976.htm).
