Firefly genomes illuminate parallel origins of bioluminescence in beetles

Fireflies and their luminous courtships have inspired centuries of scientific study. Today firefly luciferase is widely used in biotechnology, but the evolutionary origin of bioluminescence within beetles remains unclear. To shed light on this long-standing question, we sequenced the genomes of two firefly species that diverged over 100 million-years-ago: the North American Photinus pyralis and Japanese Aquatica lateralis. To compare bioluminescent origins, we also sequenced the genome of a related click beetle, the Caribbean Ignelater luminosus, with bioluminescent biochemistry near-identical to fireflies, but anatomically unique light organs, suggesting the intriguing hypothesis of parallel gains of bioluminescence. Our analyses support independent gains of bioluminescence in fireflies and click beetles, and provide new insights into the genes, chemical defenses, and symbionts that evolved alongside their luminous lifestyle

A revision of the Hypnoidinae of the world (col. Elateridae): Part I. Introduction, phylogeny, biogeography. The Hypnoidinae of north and south America. The genera Berninelsonius and Ligmargus

Both the limits of the subfamily Hypnoidinae, and its position relative to the family Elateridae as a whole, have long been subject to confusion among entomologists. As in all groups a great number of new species were described cluring the 19th and early 20th Century, and many of these species are now properly placed in the subfamily NegastriinaePeer reviewe

North American Negastriinae (Coleoptera, Elateridae): The Negastriinae of the eastern United States and adjacent Canada

Eighteen species of Negastriinae (Coleoptera, Elateridae) from Eastern North America are keyed, with illustrations, diagnoses and maps for all species. Included are five new species: Negastrius arnetti, Paradonus beckeri, P. illinoiensis, P. jerseiensis and P. olivereae. One name, Negastrius exiguus (Randall) is restored from synonymy. Four species, Negastrius extricatus (Fall), Neohypdonus aestivus (Horn), Neohypdonus restrictulus (Mannerheim) and Paradonus obliquatulus (Melsheimer) represent new combinations. Illustrations of the male genitalia of all species and representative female genitalia of each genus are given
