Elateroidea is a large taxonomic group with ~24,000 described species and interesting from the evolutionary point of view because of bioluminescence, neoteny and mimicry present in distantly related lineages. In the currently established higher-classification of Elateroidea, many lineages were transferred from three different superfamilies, Artematopoidea, Elateroidea and Cantharoidea, by both morphology- and/or molecular-based phylogenetic studies. We herein review on the phylogenetic history of Elateroidea and also prospect to construct of its robust phylogenetic hypothesis among Elateroid lineages.
False click beetles have been barely studied in the Korean peninsula. As a result of the present study, a total of 22 species belonging to 14 genera of Eucnemidae are reviewed from Korea, including two new species and 15 new records. Also, we conducted molecular phylogenetic study of the family Eucnemidae for estimating monophyly based on molecular fragments of mitochondrial protein coding gene (cytochrome c oxidase subunit I gene, COI) and two nuclear ribosomal RNA genes (18S rRNA and 28S rRNA) by Bayesian Inference (BI) and Maximum Likelihood (ML) analysis. The result of the phylogenetic analyses indicated that Eucnemidae is a monophyletic group in Elateroidea, however, mostly form paraphyly compared to previous classification in subfamily level.
A total of 13 species of Eucnemidae are recognized from Korea, including 11 species new to Korea. Descriptions, illustrations and keys to each species are provided.
