    We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S, COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 outgroups and 133 araneid ingroups representing the subfamilies Zygiellinae Simon, 1929, Nephilinae Simon, 1894, and the typical araneids, here informally named the “ARA Clade”. The araneid genera analysed here include roughly 90% of all currently named araneid species. The ARA Clade is the primary focus of this analysis. In taxonomic terms, outgroups comprise 22 genera and 11 families, and the ingroup comprises three Zygiellinae and four Nephilinae genera, and 85 ARA Clade genera (ten new). Within the ARA Clade, we recognize ten informal groups that contain at least three genera each and are supported under Bayesian posterior probabilities (≥ 0.95): “Caerostrines” (Caerostris, Gnolus and Testudinaria), “Micrathenines” (Acacesia, Micrathena, Ocrepeira, Scoloderus and Verrucosa), “Eriophorines” (Acanthepeira, Alpaida, Eriophora, Parawixia and Wagneriana), “Backobourkiines” (Acroaspis, Backobourkia, Carepalxis, Novakiella, Parawixia, Plebs, Singa and three new genera), “Argiopines” (Arachnura, Acusilas, Argiope, Cyrtophora, Gea, Lariniaria and Mecynogea), “Cyrtarachnines” (Aranoethra, Cyrtarachne, Paraplectana, Pasilobus and Poecilopachys), “Mastophorines” (Celaenia, Exechocentrus and Mastophora,), “Nuctenines” (Larinia, Larinioides and Nuctenea), “Zealaraneines” (Colaranea, Cryptaranea, Paralarinia, Zealaranea and two new genera) and “Gasteracanthines” (Augusta, Acrosomoides, Austracantha, Gasteracantha, Isoxya, Macracantha, Madacantha, Parmatergus and Thelacantha). Few of these groups are currently corroborated by morphology, behaviour, natural history or biogeography. We also include the large genus Araneus, along with Aculepeira, Agalenatea, Anepsion, Araniella, Cercidia, Chorizopes, Cyclosa, Dolophones, Eriovixia, Eustala, Gibbaranea, Hingstepeira, Hypognatha, Kaira, Larinia, Mangora, Metazygia, Metepeira, Neoscona, Paraplectanoides, Perilla, Poltys, Pycnacantha, Spilasma and Telaprocera, but the placement of these genera was generally ambiguous, except for Paraplectanoides, which is strongly supported as sister to traditional Nephilinae. Araneus, Argiope, Eriophora and Larinia are polyphyletic, Araneus implying nine new taxa of genus rank, and Eriophora and Larinia two each. In Araneus and Eriophora, polyphyly was usually due to north temperate generic concepts being used as dumping grounds for species from southern hemisphere regions, e.g. South-East Asia, Australia or New Zealand. Although Araneidae is one of the better studied spider families, too little natural history and/or morphological data are available across these terminals to draw any strong evolutionary conclusions. However, the classical orb web is reconstructed as plesiomorphic for Araneidae, with a single loss in “cyrtarachnines”–“mastophorines”. Web decorations (collectively known as stabilimenta) evolved perhaps five times. Sexual dimorphism generally results from female body size increase with few exceptions; dimorphic taxa are not monophyletic and revert to monomorphism in a few cases

    'Vacation for your teeth' - dental tourists in Hungary from the perspective of Hungarian dentists

    Background Hungary has become a popular destination for foreign patients in the last two decades, particularly in dental care. Since 2008, increasing prices in Western Europe coupled with Hungary's accessibility and availability of dental treatment, has meant the country has become a leader in 'dental tourism'. As the quality of care in Hungary is high and prices are more affordable than in Western Europe, and due to the freedom of movement of people, services and goods within the EU, patient flow into Hungary has increased progressively.Objectives The aim of this article is to provide comprehensive empirical evidence from the perspective of a recipient country in dental tourism.Methods A questionnaire survey was conducted among Hungarian dentists (n = 273). Qualitative in-depth interviews were conducted with representatives of dental professional bodies (n = 10). Both research methods aimed to elicit dentists' views on the presence of dental tourism - particularly the push and pull factors (for example, source countries, competitors, information sources, patient motivation).Results The findings show that there are several reasons why Hungary could maintain a leading position in dental tourism. First, the cost/benefit ratio is outstanding. The affordable price and value for money were already recognised in the early 1990s and were appreciated even before Hungary joined the EU. Secondly, the high quality of Hungary's dental profession: a) dental professionals in Hungary are well-qualified dental practitioners who have received high level dental training; b) dental professional standards are up-to-date and often supervised; c) in Hungary dental technology, the quality of materials and equipment used in dental practices is of European level quality. The rate of complications in dental care is around 5%, similar to other European countries. Finally, previous treatment experiences are positive and patient satisfaction levels are high. More and more patients seek care in Hungary, and more and more patients state that they would be willing to return for further treatment in the future
