Abstract

Wing characters of the genus Eucanthus are examined. These confirm the genus' placement as the most primitive in the Geotrupidae. It comprises two lineages, a primitive Nearctic, and a derived Neotropical-Australian lineage. The current disjunct distribution of the genus reflects an ancient separation with the two lineages being relictual. Wing characters demonstrate that the Bolboceratini, as it is currently recognized, is a polyphyletic tribe. It is hypothesized that Eucanthus is the sister group of the Bolboceratini+Athyreini lineage. This accounts for the morphological gap between them. It is recommended that Eucanthus be elevated to tribe status, with the two lineages consequently being elevated to generic status.
