    The genus Eumerus Meigen, 1822 (Diptera: Syrphidae) is one of the most diverse hoverfly genera in the west Palaearctic Region with 140 confirmed species and 80 occurring in the European continent. It is also highly diverse in the Iberian Peninsula plus the Balearic and Canary Islands with 43 species. Recent works on this genus have increased the number of species endemic to the Iberian Peninsula up to five. Nowadays, taxonomy, distribution and biology of the Iberian Eumerus taxonomy are still far to be fully understood. The aim of this work is to present an updated overview of the Eumerus taxonomy and diversity in the Iberian area, addressing main topics pending of resolution in the genus.El género Eumerus Meigen, 1822 (Diptera: Syrphidae) es uno de los géneros de sírfidos más diversos en la Región Paleártica con 140 especies confirmadas y 80 presentes en el continente Europeo. Es también muy diverso en la Península Ibérica e Islas Baleares y Canarias con 43 especies. Recientes publicaciones sobre este género han aumentado a cinco el número de especies endémicas para la Península Ibérica. En la actualidad, la taxonomía, distribución y biología de los Eumerus ibéricos están lejos de ser comprendidas completamente. El objetivo de este trabajo es presentar una visión actualizada de la taxonomía y diversidad de Eumerus en el área Ibérica, enfocando los principales temas pendientes de ser resueltos en este género.This research is part of Pablo Aguado-Aranda’s PhD thesis (Ref.

    Five genera of Brachyopini, Chrysogaster Meigen, 1800, Melanogaster Rondani, 1857, Lejogaster Rondani, 1857, Orthonevra Macquart, 1829 and Riponnensia Maibach et al. 1994a are here revised from the Iberian region. Two new species, Melanogaster baetica Ricarte and Nedeljković, sp. n. and Orthonevra arcana Ricarte and Nedeljković sp. n., are described from Spain, and a third species, Chrysogaster coerulea Strobl in Czerny and Strobl, 1909 stat. n., is reinstated as valid and redescribed. A lectotype is designated for Orthonevra plumbago (Loew, 1840). The holotype of Orthonevra incisa (Loew, 1843) and the lectotype of O. plumbago are described in detail and illustrated. Melanogaster baetica sp. n. is similar to Melanogaster parumplicata (Loew, 1840) in male genitalia morphology, while O. arcana sp. n. is similar to O. incisa in the entirely-pollinose sternum I and the conspicuous incision on the posterior margin of tergum V in female. The first Iberian record of Chrysogaster rondanii Maibach and Goeldlin de Tiefenau, 1995 is provided, whilst Melanogaster aerosa is removed from the Iberian checklist of Syrphidae. Identification keys are presented to the five Brachyopini genera and 18 species now reported from the Iberian Peninsula (Chrysogaster, 6 spp.; Lejogaster, 2 spp.; Melanogaster, 3 spp.; Orthonevra, 5 spp.; Riponnensia, 2 spp.). COI (Cytochrome c oxidase subunit I) barcodes of the two new species plus C. coerulea, Chrysogaster solstitialis (Fallén, 1817), Orthonevra nobilis (Fallén, 1817) and Orthonevra frontalis (Loew, 1843) were successfully obtained from Spanish specimens. A COI-based tree was produced to locate these taxa in a wider systematic framework within the tribe.This study was funded by the ‘Fauna Ibérica’ project (PGC2018-095851-A-C65) of the ‘Ministerio de Ciencia, Innovación y Universidades’ and the ‘Vicerrectorado de Investigación y Transferencia del Conocimiento’ through Antonio Ricarte’s position grant (Ref.

    The hoverfly genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) comprises 250+ described species, of which 36 are reported from the Iberian Peninsula. The high species diversity linked to the low degree of morphological differentiation between some species, which is even lower in females, leads to a high taxonomic complexity in this genus. The aim of this work is to confirm the morphological and molecular validity of an undescribed species of Eumerus, which is widespread in the Iberian Peninsula. The new species is described and compared with similar species. The genitalia of the new species are similar to those of Eumerus clavatus Becker, 1923 and Eumerus uncipes Rondani, 1850, but also share some features with Eumerus nudus Loew, 1848. The COI-5’ barcode is provided for the new taxon and analysed together with those of other named Eumerus sequences/species publicly available online. In the light of the morphology and barcoding data, the systematic position of the new species is discussed.This research is part of Pablo Aguado-Aranda’s PhD thesis, which is devoted to the revision of the Iberian Eumerus, and is funded by the ‘Fauna Ibérica’ project (PGC2018-095851-A-C65) and the ‘Ministerio de Ciencia e Innovación’ fellowship program (Ref.

    The present paper analyses the effect of self-efficacy in sports injury and to what extent such effect is mediated by coping strategies to competitive situations shown by athletes. 245 sportspeople were assessed regarding the number of injuries suffered the last 12 months, General selfefficacy and coping strategies. regression analysis proved that two coping strategies, emotional calming and risk behavior, predicted the suffering of less or more injuries, respectively. A path analysis showed that self-efficacy was not directly related to the number of injuries but indirectly through coping strategies. Unexpectedly, the greater self-efficacy induces both coping strategies oriented to trying new options and risky alternatives (risk behavior) and coping strategies directed to control negative emotions (emotional calming) which would supposedly be related to least risk-taking behaviors, the former increasing and the later decreasing vulnerability to sports injuryEl presente estudio analiza el efecto de la autoeficacia en la lesión deportiva y en qué medida ese efecto se ve mediado por las estrategias de afrontamiento ante la situación competitiva que los deportistas exhiban. Se evaluaron el número de lesiones en los últimos 12 meses, la autoeficacia general y las estrategias de afrontamiento de 245 deportistas. Un análisis de regresión mostró que dos de las estrategias de afrontamiento: calma emocional y tendencia al riesgo, predecían el padecimiento de un menor o mayor número de lesiones, respectivamente. Un path analysis mostró que la autoeficacia no incidía directamente en el número de lesiones sino que las estrategias de afrontamiento mediaban esa relación. Contra lo esperado, una mayor autoeficacia induce tanto estrategias que llevan a intentar nuevas alternativas y opciones arriesgadas (conductas de riesgo) como otras que intentan controlar las emociones negativas (calma emocional) que, supuestamente, estarían relacionadas con menores conductas de riesgo. En el primer caso incrementando y en el segundo decrementando la vulnerabilidad a las lesionesO presente estudo analisa o efeito da autoeficacia na lesão esportiva e em que medida este efeito é mediado por estratégias de enfrentamento à situação de concorrência que os atletas apresentam. Foram avaliados o número de lesões nos últimos 12 meses, a auto-eficácia geral e as estratégias de enfrentamento de 245 atletas. A análise de regressão mostrou que duas estratégias de enfrentamento: calma emocional e tendência ao risco previu o sofrimento de um número menor ou maior de lesões, respectivamente. A path analysis mostrou que a auto-eficácia não influencia diretamente o número de lesionados, mas as estratégias de enfrentamento mediam essa relação. em contra as expectativas, uma maior auto-eficácia induz tanto estratégias levam a tentar novas alternativas e opções arriscadas (comportamentos de risco ) assim como outras que tentam controlar as emoções negativas (emotional calma) que, supostamente, estariam relacionados com comportamentos de menor risco.

    Numerosas observaciones y estudios que se han llevado a cabo en las últimas décadas demuestran que, además de las abejas (Hymenoptera; Anthophila) otros grupos de insectos desempeñan un papel primordial en la polinización entomófila. En este artículo se revisa la información y bibliografía disponible sobre la contribución de los principales polinizadores tradicionalmente considerados como "secundarios": los coleópteros, los lepidópteros, los dípteros, las avispas y las hormigas. Para cada uno de estos grupos se sigue un esquema común, con una breve introducción, la enumeración de las características básicas -tanto morfológicas como de comportamiento- en relación con la polinización, su efectividad como polinizadores y el estatus de conservación en la península ibérica. Esta revisión pone de manifiesto la importancia de todos estos grupos en la polinización entomófila y la necesidad de incluirlos en estudios exhaustivos sobre este fenómeno. Aunque los datos existentes en general son muy limitados, también se evidencia un declive general en la mayoría de estos grupos y una necesidad apremiante de mejorar los conocimientos sobre sus tendencias poblacionales.Numerous observations and studies that have been carried out in recent decades show that, in addition to bees ((Hymenoptera; Anthophila), other groups of insects play a major role in entomophilous pollination. This article reviews the information and literature available on the contribution of the main groups of pollinators that traditionally have been considered as "secondary": beetles, butterflies and moths, dipterans, wasps and ants. For each of these groups a common outline is followed, with a brief introduction, a summary of the basic characteristics - both morphological and behavioral - in relation to pollination, their effectiveness as pollinators and their conservation status in the Iberian Peninsula. This review highlights the importance of all these groups in entomophilous pollination and the need to include them in comprehensive studies on this phenomenon. Although data are generally very limited, there is clear evidence of a general decline in most of these groups which calls for a pressing need to improve knowledge about their population trends
