The first fossil longhorn beetles (Coleoptera: Cerambycidae) from Australia.

Longhorn beetles (family Cerambycidae) are globally distributed insects with important ecological roles. Here we present the first discovery of fossil longhorn beetles from Australia. The two new taxa described, Ventiala beattiei gen.

Chromosome Structural Rearrangements in Invasive Haplodiploid Ambrosia Beetles Revealed by the Genomes of Euwallacea fornicatus (Eichhoff) and Euwallacea similis (Ferrari) (Coleoptera, Curculionidae, Scolytinae).

Bark and ambrosia beetles are among the most ecologically and economically damaging introduced plant pests worldwide. Life history traits including polyphagy, haplodiploidy, inbreeding polygyny, and symbiosis with fungi contribute to their dispersal and impact. Species vary in their interactions with host trees, with many attacking stressed or recently dead trees, such as the globally distributed Euwallacea similis (Ferrari).

Evolution across the adaptive landscape in a hyperdiverse beetle radiation.

The extraordinary diversification of beetles on Earth is a textbook example of adaptive evolution. Yet, the tempo and drivers of this super-radiation remain largely unclear. Here, we address this problem by investigating macroevolutionary dynamics in darkling beetles (Coleoptera: Tenebrionidae), one of the most ecomorphologically diverse beetle families (with over 30,000 species).

gen. nov., an unusual cleroid genus with large hypomeral cavities from mid-Cretaceous amber (Coleoptera: Cleroidea).

Beetles have a remote evolutionary history dating back to the Carboniferous, with Mesozoic fossils playing a pivotal role in elucidating the early evolution of extant families. Despite their exceptional preservation in amber, deciphering the systematic positions of Mesozoic trogossitid-like beetles remains challenging. Here, we describe and illustrate a new trogossitid-like lineage from mid-Cretaceous Kachin amber, Li, Kolibáč, Liu & Cai, gen.

Museomics unveil systematics, diversity and evolution of Australian cycad-pollinating weevils.

Weevils have been shown to play significant roles in the obligate pollination of Australian cycads. In this study, we apply museomics to produce a first molecular phylogeny estimate of the Australian cycad weevils, allowing an assessment of their monophyly, placement and relationships. Divergence dating suggests that the Australian cycad weevils originated from the Late Oligocene to the Middle Miocene and that the main radiation of the cycad-pollinating groups occurred from the Middle to the Late Miocene, which is congruent with the diversification of the Australian cycads, thus refuting any notion of an ancient ciophilous system in Australia.

The Australian genus Rhytiphora (Coleoptera: Cerambycidae: Lamiinae) with a revision of the Rhytiphora collaris group.

We present a review of the Australian species of Rhytiphora Audinet-Serville, 1835, the most speciose longhorn beetle (Cerambycidae) genus in Australia. The morphological definition of the genus is updated, including useful features to distinguish Rhytiphora from closely related genera within Niphonini. Key characteristics of the two molecularly determined subclades are also provided.

Review of the Australian endemic genus Tasmosalpingus Lea, 1919 (Coleoptera, Cucujoidea, Tasmosalpingidae).

The sole genus of the Australian endemic family Tasmosalpingidae, Tasmosalpingus Lea, 1919, is revised and T. promiscuus Lea, 1919 is proposed as a junior synonym of T. quadrispilotus Lea, 1919.

Platycrus-a remarkable new genus of the tribe Platynaspini (Coleoptera: Coccinellidae) from Laos.

A new remarkable ladybird beetle Platycrus laotanus gen. et sp. nov.

Integrated phylogenomics and fossil data illuminate the evolution of beetles.

Beetles constitute the most biodiverse animal order with over 380 000 described species and possibly several million more yet unnamed. Recent phylogenomic studies have arrived at considerably incongruent topologies and widely varying estimates of divergence dates for major beetle clades. Here, we use a dataset of 68 single-copy nuclear protein-coding (NPC) genes sampling 129 out of the 193 recognized extant families as well as the first comprehensive set of fully justified fossil calibrations to recover a refined timescale of beetle evolution.

A New Genus and Species of Lophocateridae from Mid-Cretaceous Amber of Myanmar (Coleoptera).

Revision of the subfamily Ostomopsinae (Coleoptera: Cerylonidae).

The subfamily Ostomopsinae of Cerylonidae is revised. Six nominal species are recognized and described or redescribed: Ostomopsis cudak sp. n.

Anchored Phylogenomics, Evolution and Systematics of Elateridae: Are All Bioluminescent Elateroidea Derived Click Beetles?

Click-beetles (Coleoptera: Elateridae) are an abundant, diverse, and economically important beetle family that includes bioluminescent species. To date, molecular phylogenies have sampled relatively few taxa and genes, incompletely resolving subfamily level relationships. We present a novel probe set for anchored hybrid enrichment of 2260 single-copy orthologous genes in Elateroidea.

The mid-Miocene Zhangpu biota reveals an outstandingly rich rainforest biome in East Asia.

During the Mid-Miocene Climatic Optimum [MMCO, ~14 to 17 million years (Ma) ago], global temperatures were similar to predicted temperatures for the coming century. Limited megathermal paleoclimatic and fossil data are known from this period, despite its potential as an analog for future climate conditions. Here, we report a rich middle Miocene rainforest biome, the Zhangpu biota (~14.

New insights into the phylogeny and evolution of lady beetles (Coleoptera: Coccinellidae) by extensive sampling of genes and species.

Ladybirds (family Coccinellidae) are one of the most diverse groups of beetles and globally comprise over 6000 species. Despite their scientific and economic significance, the taxonomy of Coccinellidae remains unstable, and we still know little about their evolutionary history. By using a small number of genes, previous phylogenetic analyses have not reliably resolved the relationships among major ladybird lineages.

Description of a new species of Eucinetidae (Coleoptera, Scirtoidea) from Cretaceous Burmese amber.

is described from late Cretaceous Burmese amber, representing the second record of Eucinetidae from the Burmese amber and the first species of the family with simple, not piercing, mouthparts. A comparison between Mesocinetidae and Eucinetidae is provided.

Discovery of the genus Cycloxenus Arrow, 1925 (Coleoptera, Euxestidae) in mainland China, with the description of a new species.

The termitophilous genus Cycloxenus Arrow (Coleoptera, Euxestidae) is reported from mainland China for the first time. A new species, Cycloxenus guangxiensis sp. nov.

The extant species of the genus Omma Newman and description of Beutelius gen. nov. (Coleoptera: Archostemata: Ommatidae: Ommatinae).

The genus Omma Newman (type species Omma stanleyi Newman) is revised and redefined based on extant species, with examination of additional fossil species. As a result, only the species O. stanleyi Newman is retained in Omma and a new genus, Beutelius gen.

The evolution and genomic basis of beetle diversity.

The order Coleoptera (beetles) is arguably the most speciose group of animals, but the evolutionary history of beetles, including the impacts of plant feeding (herbivory) on beetle diversification, remain poorly understood. We inferred the phylogeny of beetles using 4,818 genes for 146 species, estimated timing and rates of beetle diversification using 89 genes for 521 species representing all major lineages and traced the evolution of beetle genes enabling symbiont-independent digestion of lignocellulose using 154 genomes or transcriptomes. Phylogenomic analyses of these uniquely comprehensive datasets resolved previously controversial beetle relationships, dated the origin of Coleoptera to the Carboniferous, and supported the codiversification of beetles and angiosperms.

Genomic changes in the biological control agent associated with introduction.

Biological control is the main purpose of intentionally introducing non-native invertebrate species. The evolutionary changes that occur in the populations of the introduced biological control agents may determine the agent's efficiency and the environmental safety. Here, to explore the pattern and extent of potential genomic changes in the worldwide introduced predatory ladybird beetle , we used a reduced-representation sequencing method to analyze the genome-wide differentiation of the samples from two native and five introduced locations.

A Mesozoic clown beetle myrmecophile (Coleoptera: Histeridae).

Complex interspecies relationships are widespread among metazoans, but the evolutionary history of these lifestyles is poorly understood. We describe a fossil beetle in 99-million-year-old Burmese amber that we infer to have been a social impostor of the earliest-known ant colonies. gen.

Basal polyphagan beetles in mid-Cretaceous amber from Myanmar: biogeographic implications and long-term morphological stasis.

The origin and early evolutionary history of polyphagan beetles have been largely based on evidence from the derived and diverse 'core Polyphaga', whereas little is known about the species-poor basal polyphagan lineages, which include Scirtoidea (Clambidae, Decliniidae, Eucinetidae, and Scirtidae) and Derodontidae. Here, we report two new species Acalyptomerus thayerae sp. nov.

Lepicerus larva still unknown: a correction (Coleoptera: Lepiceridae, Phalacridae).

The larva of Lepicerus inaequalis Motschulsky was described by Lawrence et al. (2013) based on several early instars and one late instar collected among wet leaves and debris near Gamboa, Panama. The identification was based on collection of an adult Lepicerus in a similar habitat nearby and a combination of characters found in other myxophagan immatures but not known in other beetle larvae.
