Taxonomy of Phanaeus revisited: revised keys to and comments on species of the New World dung beetle genus PhanaeusMacLeay, 1819 (Coleoptera: Scarabaeidae: Scarabaeinae: Phanaeini)

The purpose of this paper is to reassess the taxonomy of Phanaeus MacLeay (Coleoptera: Scarabaeidae) to accommodate new taxa and changes in taxonomic opinion since the publication of Edmonds’ 1994 revision of the genus. The two subgenera and 13 species groups established by Edmonds (1994) remain unchanged. A revised set of keys with accompanying comments and illustrations separates 54 recognized valid species. Seven recently described valid species are incorporated into the revised classification: Phanaeus blackalleri Delgado-Castillo, 1991; P. bordoni Arnaud, 1996; P. changdiazi Kohlmann and Solís, 2001; P. lecourti Arnaud, 2000; P. martinezorum Arnaud, 2000; P. yecoraensis Edmonds, 2004; and P. zapotecus Edmonds, 2006. The new name Phanaeus sororibispinus Edmonds and Zidek replaces Phanaeus alvarengai Arnaud, 1984, a primary junior homonym of P. alvarengai Pereira and d’Andretta, 1955. Three subspecies recognized in 1994 are elevated to species rank, new status: Phanaeus texensis Edmonds, 1994; P. pilatei Harold, 1863; and P. guatemalensis Harold, 1871. Phanaeus obliquans Bates, 1887 is removed from synonymy and given new status as a valid species. Twelve new junior subjective synonyms (bold) are recognized: P. tridens balthasari Arnaud, 2002 (of P. tridens Castelnau, 1840); P. dzidoi Arnaud, 2000 (of P. palaeno Blanchard, 1843); P. genieri Arnaud, 2002 (of P. amethystinus Harold, 1863); P. prasinus jolyi Arnaud, 2001 (of P. prasinus Harold, 1868); P. kirbyi ledezmai Arnaud, 2002 (of P. kirbyi Vigors, 1825); P. achilles lydiae Arnaud, 2000 (of P. achilles Boheman, 1858); P. chalcomelas grossii Arnaud, 2001 (of P. chalcomelas [Perty, 1830]); P pyrois malyi Arnaud, 2002 (of P. pyrois Bates, 1887); P. tridens moroni Arnaud, 2001 (of P. tridens Castenau, 1840); P. lecourti peruanus Arnaud, 2000 (of P. lecourti Arnaud, 2000); P. endymion porioni Arnaud, 2001 (of P. endymion Harold, 1863); P. pseudofurcosus Balthasar, 1939 (of P. tridens Castelnau, 1840); and P. prasinus trinidadensis Arnaud, 2001 (of P. prasinus Harold, 1868). “Phanaeus viridicollis” Olsoufieff, 1924 (sensu Arnaud 2002) is an unavailable name here considered a color variant of P. pyrois Bates, 1887

A taxonomic review of the neotropical genus Coprophanaeus Olsoufieff, 1924 (Coleoptera: Scarabaeidae, Scarabaeinae)

The Neotropical genus Coprophanaeus Olsoufieff (1924), as classified here, comprises 38 species distributed among three subgenera (Megaphanaeus Olsoufieff, Metallophanaeus Olsoufieff, and Coprophanaeus s. str.) and eight species groups. Keys presented help to identify supraspecific and species taxa, all of which are illustrated and diagnosed. Lectotypes are designated for Phanaeus ignecinctus Felsche and Phanaeus ohausi Felsche. Coprophanaeus corythus (Harold), formerly regarded as a subspecies of C. telamon (Erichson), assumes species status. Coprophanaeus magnoi Arnaud, described as a subspecies of C. milon (Blanchard), is raised to species status. New taxonomic interpretations result in 10 new subjective synonymies (junior synonym listed first): Phanaeus machadoi Pereira and d’Andretta = Coprophanaeus saphirinus (Perty); Phanaeus costatus Olsoufieff = Coprophanaeus cyanescens (Olsoufieff); Phanaeus worontzowi Pessôa and Lane = Coprophanaeus cyanescens (Olsoufieff); Coprophanaeus kohlmanni Arnaud = Coprophanaeus morenoi Arnaud; Coprophanaeus pluto nogueirai Arnaud = Coprophanaeus pluto (Harold); Coprophanaeus edmondsi Arnaud = Coprophanaeus conocephalus (Olsoufieff); Coprophanaeus uhleri Malý and Pokorný = Coprophanaeus chiriquensis (Olsoufieff); Coprophanaeus henryi Malý and Pokorný = Coprophanaeus gilli Arnaud; Phanaeus perseus Harold = Coprophanaeus corythus (Harold); Coprophanaeus telamon nevinsoni Arnaud and Gámez = Coprophanaeus corythus; and Coprophanaeus florenti Arnaud = Coprophanaeus ohausi (Felsche). The status of the following names remains unresolved: Phanaeus strandi Balthasar; Coprophanaeus rigoutorum Arnaud; C. terrali Arnaud; C. lichyi Arnaud; C. lecromi Arnaud; C. larseni Arnaud; and C. vazdemeloi Arnaud

The genus Gromphas Brullé (Coleoptera: Scarabaeidae) comprises four species, of which G. aeruginosa (Perty) and G. amazonica Bates are known to occur in Peru. This paper presents a revised description of Gromphas as well as illustrated diagnoses and distributional and ecological data on the Peruvian species

Counseling Athletes Who Use Performance-Enhancing Drugs: A New Conceptual Framework Linked to Clinical Practice

Doping, the use of performance-enhancing drugs by athletes, is a major concern that the media have publicized prominently. Sport governing bodies currently use two primary methods to dissuade athletes from doping: punishment and didactic education. Neither of these approaches has eradicated doping from competitive athletics because the practice appears to be increasing. Including clinical interventions in systemic campaigns that address this problem would be efficacious. The current article provides a conceptual framework that addresses doping from a psychologist’s perspective and then operationalizes this framework, all the while identifying the unique environment in which athletes function. Practical interventions for working with clients who dope are identified, as are possible future research paths that could benefit work with this population

Mixing and crystal scavenging in the Main Ethiopian Rift revealed by trace element systematics in feldspars and glasses

For many magmatic systems, crystal compositions preserve a complex and protracted history which may be largely decoupled from their carrier melts. The crystal cargo may hold clues to the physical distribution of melt and crystals in a magma reservoir and how magmas are assembled prior to eruptions. Here we present a geochemical study of a suite of samples from three peralkaline volcanoes in the Main Ethiopian Rift. Whilst whole-rock data shows strong fractional crystallisation signatures, the trace element systematics of feldspars, and their relationship to their host glasses, reveals complexity. Alkali feldspars, particularly those erupted during caldera forming episodes, have variable Ba concentrations, extending to high values that are not in equilibrium with the carrier liquids. Some of the feldspars are antecrysts, which we suggest are scavenged from a crystal-rich mush. The antecrysts crystallised from a Ba-enriched (more primitive) melt, before later entrainment into a Ba-depleted residual liquid. Crystal-melt segregation can occur on fast timescales in these magma reservoirs, owing to the low viscosity nature of peralkaline liquids. The separation of enough residual melt to feed a crystal-poor post caldera rhyolitic eruption may take as little as months to tens of years (much shorter than typical repose periods of 300-400 years). Our observations are consistent with these magmatic systems spending significant portions of their life cycle dominated by crystalline mushes containing ephemeral, small (< 1 km3) segregations of melt. This interpretation helps to reconcile observations of high crustal electrical resistivity beneath Aluto, despite seismicity and ground deformation consistent with a magma body.This project is funded by the Natural Environment Research Council grant NE/L013932/1 (RiftVolc)

Climate Science Special Report: Fourth National Climate Assessment (NCA4), Volume I

New observations and new research have increased our understanding of past, current, and future climate change since the Third U.S. National Climate Assessment (NCA3) was published in May 2014. This Climate Science Special Report (CSSR) is designed to capture that new information and build on the existing body of science in order to summarize the current state of knowledge and provide the scientific foundation for the Fourth National Climate Assessment (NCA4)

The British Army, information management and the First World War revolution in military affairs

Information Management (IM) – the systematic ordering, processing and channelling of information within organisations – forms a critical component of modern military command and control systems. As a subject of scholarly enquiry, however, the history of military IM has been relatively poorly served. Employing new and under-utilised archival sources, this article takes the British Expeditionary Force (BEF) of the First World War as its case study and assesses the extent to which its IM system contributed to the emergence of the modern battlefield in 1918. It argues that the demands of fighting a modern war resulted in a general, but not universal, improvement in the BEF’s IM techniques, which in turn laid the groundwork, albeit in embryonic form, for the IM systems of modern armies.
