Campyloxenus is a bioluminescent genus of click beetles in the family Elateridae, and had been the sole member of the subfamily Campyloxeninae, until another monotypic genus Malalcahuello [species] was described from Chile in 2015 as its new member.^[1] There is one described species in Campyloxenus, Campyloxenus pyrothorax,^[2][3] from southwestern Chile and Argentina.^[4]
