The deep-soil sampling in Chile revealed a new elateroid beetle lineage, Badmaateridae fam. nov. (Coleoptera)

Deep-soil arthropods remain one of the least studied components of terrestrial biodiversity, and we present, as an exciting discovery, a new endogean beetle collected by floating deep soil samples in Chile. We analyzed a 4,203-ortholog dataset using both maximum likelihood and coalescent methods to infer its relationships. Regardless of the analytical setup, Badmaater was recovered as the sister to the clade consisting of Lycidae, Cantharidae, Elateridae, and the lampyroids. The distant position of Badmaater relative to the previously described elateroid families is confirmed by additional analyses of differently sampled, although less phylogenetically informative, 66-gene and mitogenome datasets. As a result, we describe Badmaater chilensis sp. and gen. nov. in Badmaateridae fam. nov. (Coleoptera: Elateroidea). Badmaater resembles other clicking elateroids, but has a three-segmented antennal club, slender palpi, and globular metacoxae that are situated close to each other. It is blind,..., , ## File Description
