Genetic research in Zhou et al. (2022) revealed that the species is closely related to a widespread species,
Trogoderma angustum and other species originating from South America (including the genus
Sodaliotoma). All of these species are considered by some authors to belong to the genus
Eurhopalus, many of which were previously considered to be
Trogoderma. Under the proposed classification of Zhou et al. (2022), the species is
Eurhopalus vespulae, however the change is not yet accepted by some researchers. ==References==
