Beetles of the world: a natural history
Beetles make up about a quarter of known animal species and are arguably the most diverse group of organisms on Earth: almost 400,000 species have been formally described so far, and it is likely that this number merely scratches the surface. In Beetles of the World, Maxwell Barclay and Patrice Bouchard--two of the world's foremost beetle experts--celebrate these remarkable creatures in all their variety, from their size and appearance to their ecological importance.

THE AUTOMATION AND EVALUATION OF NESTED CLADE PHYLOGEOGRAPHIC ANALYSIS
Nested clade phylogeographic analysis (NCPA) is a popular method for reconstructing the demographic history of spatially distributed populations from genetic data. Although some parts of the analysis are automated, there is no unique and widely followed algorithm for doing this in its entirety, beginning with the data, and ending with the inferences drawn from the data. This article describes a method that automates NCPA, thereby providing a framework for replicating analyses in an objective way. To do so, a number of decisions need to be made so that the automated implementation is representative of previous analyses. We review how the NCPA procedure has evolved since its inception and conclude that there is scope for some variability in the manual application of NCPA. We apply the automated software to three published datasets previously analyzed manually and replicate many details of the manual analyses, suggesting that the current algorithm is representative of how a typical user will perform NCPA. We simulate a large number of replicate datasets for geographically distributed, but entirely random-mating, populations. These are then analyzed using the automated NCPA algorithm. Results indicate that NCPA tends to give a high frequency of false positives. In our simulations we observe that 14% of the clades give a conclusive inference that a demographic event has occurred, and that 75% of the datasets have at least one clade that gives such an inference. This is mainly due to the generation of multiple statistics per clade, of which only one is required to be significant to apply the inference key. We survey the inferences that have been made in recent publications and show that the most commonly inferred processes (restricted gene flow with isolation by distance and contiguous range expansion) are those that are commonly inferred in our simulations. However, published datasets typically yield a richer set of inferences with NCPA than obtained in our random-mating simulations, and further testing of NCPA with models of structured populations is necessary to examine its accuracy.

Dermestidae (Coleoptera)
The World Catalogue of the Dermestidae (Coleoptera) contains the list of subfamilies, tribes and subtribes, list of genera and subgenera, systematic catalogue of all known taxons including new nomenclatorial acts, new distributional records, list of type depositions, infrasubspecific names, bibliography and alphabetical index of names of genera, subgenera and their synonyms. It contains all the taxa described until February 28, 2014.

Australian Beetles Volume 1
This three-volume series represents a comprehensive treatment of the beetles of Australia, a relatively under-studied fauna that includes many unusual and unique lineages found nowhere else on Earth. Volume 1 contains keys to all 117 beetle families found in Australia, and includes over 1100 illustrations of adults, larvae and anatomical structures. This volume is based in part on Lawrence Britton's out-of-print Australian Beetles, but is fully updated and expanded. The biology and morphology for all major beetle lineages is described and illustrated, along with anatomical terms which clarify the characters and terminology used in the keys; few other resources for beetle identification include such a detailed morphological background. A chapter on the fossil record is also included, and family sections provide full descriptions of adults and larvae, including the world distribution of each family. The revised identification keys (currently recognised as one of the most valuable keys worldwide) will aid quarantine agents, biologists and students in identifying members of the most species-rich order of animals.

Coleoptera: Staphylinidae: Scaphidiinae
The present Catalogue comprises information on 48 genera and 1802 valid species of the coleopterous subfamily Scaphidiinae. Unlike previous catalogues of the group, it gives exact type localities, depositories and sexes of primary types whenever traceable. Genera are listed with their type species and grammatical gender. References are given to subsequent taxonomic and nomenclatural acts, records, and to all other relevant information. Distributional information is provided per country, for larger or insular countries per subunits. An overview of fungus and slime mould hosts is annexed. The references to all taxa have been checked by the author. Infrasubspecific entities and priorities are dealt to comply with the ICZN. Nomenclatural problems are highlighted, and several new records are given. Extinct taxa are listed separately.

Curculionoidea II
Volume 8 of the Catalogue of Palaearctic Coleoptera provides a list of all taxa of the bulk of the family Curculionidae and of Cryptolaryngidae reported from the biogeographical realm covered. For the genus and species-groups taxa all available names are given, and for the valid species and subspecies the distribution per country is shown, including more details for endemic taxa. Type species are listed for all genus-group names. The work is based on verification of the primary sources, and the respective references are given. Particular chapters deal with the actual impediments of taxonomy, nomenclatural and taxonomic problems, and corrections to previously published volumes of the Catalogue.

CAPTURE EFFICIENCY AND PRESERVATION ATTRIBUTES OF DIFFERENT FLUIDS IN PITFALL TRAPS
Pitfall traps are widely used to capture arthropods. The type of fluid employed in the traps can affect size and condition of the catch. Direct comparisons of different fluids allow entomologists to avoid suboptimal solutions, and facilitate comparisons between studies using different fluids. We compared capture efficiency and preservation attributes between five fluids in a field experiment with special respect to spiders (Araneae) and ground beetles (Coleoptera, Carabidae). Catches in pure water, ethanol-water and ethanol-glycerin were less well preserved than in brine or ethylene glycol-water. Brine and ethanol-glycerin showed low capture efficiencies, presumably because their high specific density made arthropods float and thereby facilitated escape. Only the mixture of ethylene glycol and water combined good preservation attributes with high capture efficiency, and therefore represented the best solution.

La posición sistemática de Geoborus lineatus comb. nov. (ex. Gyriosomus ) (Coleoptera: Tenebrionidae)
The systematic placement of Gyriosomus lineatus Guérin-Méneville, 1834 is resolved. Geoborus costatus Blanchard, 1847 (Pimeliinae: Epitragini) is determined to be a junior synonym of Gyriosomus lineatus Guérin-Méneville 1834 (Pimeliinae: Nycteliini) and the new combination Geoborus lineatus (Guérin-Méneville, 1834) (Epitragini) is proposed. Geoborus costatus is subsequently designated the type species for Geoborus Blanchard, 1847. Comments and photographs of the type material are included. Comments of the distribution and habitat of the species are given.
Se resuelve la posición sistemática de Gyriosomus lineatus Guérin-Méneville, 1834. Geoborus costatus Blanchard, 1847 (Pimeliinae: Epitragini) se ubica como sinónimo de Gyriosomus lineatus Guérin-Méneville, 1834 (Pimeliinae: Nycteliini), y se propone como nueva combinación a Geoborus lineatus (Guérin-Méneville, 1834) (Epitragini). Se designa subsecuentemente a Geoborus costatus como especie tipo de Geoborus Blanchard, 1847. Se entregan antecedentes y fotografías del material tipo, y se consignan la distribución y el hábitat de la especie.
