Cet ouvrage n’est pas un guide d’identification, mais une introduction aux Coléoptères peuplant la région du bassin genevois. Les espèces présentées ont été sélectionnées pour leur intérêt patrimonial, pour la diversité de leurs formes et de leurs mœurs ou encore de celles des milieux où elles vivent. On y trouve ainsi des espèces dites « communes...

Cost, time, and expertise constraints limit traditional observation-based comprehensive biodiversity assessment. Therefore, surrogate focal taxa representative of wider biodiversity are commonly used as an imperfect ‘proxy’. Contemporary biodiversity assessments are also increasingly benefiting from the combination of high-throughput sequencing and...

The New World scarab beetle tribe Phanaeini contains coprophagous, necrophagous, mycetophagous and suspected myrmecophilous species. We analyse the largest tribal molecular dataset assembled, incorporating, for the first time, the enigmatic monobasic genus Megatharsis, the thalassinus group of the subgenus Coprophanaeus (Metallophanaeus), and the s...
Article
Full-text available
Complete mitochondrial genomes have been shown to be reliable markers for phylogeny reconstruction among diverse animal groups. However, the relative difficulty and high cost associated with obtaining de novo full mitogenomes has frequently led to conspicuously low taxon sampling in ensuing studies. Here we report the successful use of an economica...

Article
• The dramatic worldwide decline in insect biodiversity has highlighted the need for insect conservation. However, management is hindered by incomplete knowledge of what drives species mortality. Even when drivers are identified, it can be difficult to quantify their effects. • Using data from six naturally occurring cohorts observed over 2 years,...

Phymastichus coffea LaSalle (Hymenoptera:Eulophidae) is an adult endoparasitoid of the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera:Curculionidae:Scolytinae), which has been introduced in many coffee producing countries as a biological control agent. To determine the effectiveness of P. coffea against H. hampei and environmental sa...
Article
Some invasive plants are used by native wildlife but may be subject to control measures. We investigated oviposition preferences of an endangered moth dependent upon an invasive weed for survival. By identifying preferred characteristics of invasive host plants, land managers may minimize resource loss for imperiled species dependent upon them. Som...

Advances in phylogenomics contribute towards resolving long-standing evolutionary questions. Notwithstanding, genetic diversity contained within more than a billion biological specimens deposited in natural history museums remains recalcitrant to analysis owing to challenges posed by its intrinsically degraded nature. Yet that tantalizing resource...
Article
A survey for scolytine bark and ambrosia beetles undertaken on the entomologically understudied and ecologically devastated Hawaiian island of Lāna‘i, revealed the remarkable presence there of Xyleborus mauiensis Perkins, 1900, an endemic Hawaiian ambrosia beetle in the tribe Xyleborini not previously recorded from the island. Its presence on Lāna‘...

The cryptic species that make up the Euwallacea fornicatus species complex can be readily distinguished via their DNA sequences. Until recently, it was believed that the Hawaiian Islands had been invaded by only one of these cryptic species, E. perbrevis (tea shot hole borer; TSHB). However, following the 2016 deposition of a DNA sequence in the pu...

We describe Bulasconotus scaccarius sp. nov., a new species of cylindrical bark beetle (Zopheridae: Colydiinae: Synchitini), elevating the number of described species in its genus to two. Despite discovering this species in Hawaii, we suspect, based on collections and survey data, that it is endemic to the South Pacific archipelago of Vanuatu and h...
Article
We describe Dinacoma sanfelipe sp. nov. from southern California, the first new species belonging to the melolonthine scarab beetle genus Dinacoma Casey, 1889 (Scarabaeidae: Melolonthinae: Melolonthini) to be described in 90 years, based upon examination of 141 specimens of that genus. Diagnostic comments, a dichotomous key, photographs of all spec...
Article
A sampling survey for scolytine bark beetles undertaken in Pēpē‘ōpae Bog, part of The Nature Conservancy's Kamakou Preserve on the Hawaiian island of Moloka‘i, revealed the presence there of two native species of the xyleborine genus Xyleborus Eichhoff not previously known from the island: X. obliquus Sharp, 1885, and X. vulcanus Perkins, 1900. We...

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) rely on a symbiosis with fungi for their nutrition. Symbiotic fungi are preserved and transported in specialized storage structures called mycangia. Although pivotal in the symbiosis, mycangia have been notoriously difficult to study, given their minute size and membranous st...

A phylogenetic tree at the species level is still far off for highly diverse insect orders, including the Coleoptera, but the taxonomic breadth of public sequence databases is growing. In addition, new types of data may contribute to increasing taxon coverage, such as metagenomic shotgun sequencing for assembly of mitogenomes from bulk specimen sam...

Establishing well-supported monophyletic groups is a key requirement for producing a natural classification that reflects evolutionary descent. In a phylogenetic framework this is best achieved through dense taxon sampling and the analysis of a robust character dataset, combined with statistical testing of topological hypotheses. This study assesse...

The subfamily Carabinae is a diverse clade distributed across all biogeographical regions except Antarctica. In a seminal work, René Jeannel hypothesized a Gondwanan origin for this group, but this has hitherto remained untested with molecular data. We test this hypothesis by using a supermatrix approach. We also infer the most comprehensive phylog...

Metriorhynchids were a widely distributed group of marine crocodylomorphs that thrived during the Middle Jurassic–Early Cretaceous. Within this group there is a subclade, Geosaurini, that evolved craniodential characteristics indicative of macrophagy (feeding on large-bodied prey items). When this subclade evolved and began to diversify into the my...
