Eumolpus (beetle)

''Eumolpus'' is a genus of leaf beetles in the subfamily Eumolpinae. It includes 40 species, most of which have a large size and include some of the largest members of the subfamily. They are distributed throughout the Neotropical realm, though one species ('' Eumolpus robustus'') has been recorded as far north as Arizona (in the United States).

Etymology

The name of the genus is either derived from the Ancient Greek (''eúmolpos''), or is named after Eumolpus from Greek mythology, who was the son of Poseidon and Chione.

Taxonomic history

The genus in its current sense is attributed to Weber, 1801. However, the name ''Eumolpus'' was first used in Johann Karl Wilhelm Illiger's ''Verzeichniß der Käfer Preußens'' in 1798, where it was attributed to Johann Gottlieb Kugelann, and originally consisted of European species now placed in the genera ''Chrysochus'' and ''Bromius''.

While most authors followed Weber, 1801, some recent European entomologists have followed Warchałowski, who synonymised ''Chrysochus'' with ''Eumolpus'' in 1993, designating ''Chrysomela praetiosa'' as the type species of ''Eumolpus''. This designation by Warchałowski was invalid, since Latreille had designated ''Cryptocephalus vitis'' as the type species of ''Eumolpus'' in 1810, which placed ''Bromius'' in synonymy with ''Eumolpus''. This threatened stability for ''Eumolpus'', ''Bromius'' and ''Chrysochus''.

In 2010, an application was made to the International Commission on Zoological Nomenclature to conserve the names ''Eumolpus'' Weber, 1801, ''Chrysochus'' Chevrolat in Dejean, 1836 and ''Bromius'' Chevrolat in Dejean, 1836 by suppressing the name ''Eumolpus'' Illiger, 1798, and to set aside all type species designations for ''Eumolpus'' before Hope's designation of ''Chrysomela ignita'' Fabricius, 1787 in 1840. This was accepted by the ICZN in 2012.
