Corrections to the status of Eucanthus Westwood, 1848, Bolbelasmus Boucomont, 1911, and Kolbeus Boucomont, 1911 (Coleoptera: Bolboceratidae)

Summary

The status of Eucanthus Westwood, 1848 stat. rev. is corrected. According to the Principle of Priority, Eucanthus is given genus rank, while Bolbelasmus Boucomont, 1911 stat. rev. and Kolbeus Boucomont, 1911 stat. rev. are subordinated as subgenera within Eucanthus. A corrected list for species-group names and new combinations is provided for Eucanthus. The tribe Eucanthini is considered a junior synonym of Bolbelasmini.

Moctezuma et al. (2023) incorrectly proposed Eucanthus Westwood, 1848 and Kolbeus Boucomont, 1911 as subgenera of Bolbelasmus Boucomont, 1911. According to the Principle of Priority, the correct decision is to subordinate Bolbelasmus and Kolbeus as subgenera within Eucanthus. The list of species-group names provided by Moctezuma et al. (2023) is corrected herein to provide adequate combinations. In addition, it is worth mentioning that Nikolajev (2003) considered that Eucanthus and Bolbelasmus pertained to different tribes: Eucanthini Nikolajev, 2003 and Bolbelasmini Nikolajev, 1996, respectively. Bolbelasmus was considered the type genus of Bolbelasmini, and Eucanthus the same for Eucanthini, but the tribal name Bolbelasmini has priority over Eucanthini. Consequently, Eucanthini must be considered a junior synonym of Bolbelasmini.
