Chusquea joins a growing list of living New World genera that are no longer included in Paleogene Patagonian floras, whose extant relatives are primarily concentrated in Australasia and Malesia via the ancient Gondwanan route through Antarctica. Peter Wilf.in English, Portuguese ResumoSolanum hydroides Gouvêa & Giacomin, sp. nov., é aqui descrita para região central da Floresta Atlântica brasileira. Ela é conhecida apenas para três localidades, nos estados do Espírito Santo e Minas Gerais, em uma região onde afloramentos graníticos/gnáissicos (inselbergues ou pães de açúcar) são onipresentes. A nova espécie pertence a Solanum subgen. Leptostemonum (ou Solanum clado Leptostemonum, i.e. espécies espinhentas com tricomas estrelados) e é morfologicamente semelhante a S. hexandrum Vell. e S. sublentum Hiern, com quem compartilha o hábito arbustivo, a base das lâminas foliares decurrentes e cálices bem desenvolvidos, acrescentes em seus frutos glabros. Solanum hydroides é, contudo, a única espécie que apresenta a seguinte combinação de caracteres hábito delicado, indumento composto apenas por tricomas estrelados egandulares, cálices frutíferos acrescentes, mas nunca inflados, que cobrem parcialmente os frutos e corolas com lóbulos curtos e estritamente brancas. Omecamtiv mecarbil clinical trial A espécie é considerada como ameaçada de extinção, na categoria Vulnerável (VU), segundo os critérios da IUCN.Sporades jaechi sp. nov. from Poum, New Caledonia is newly described and shown to be a member of the monophyletic Sporades subgenus Perileptosporades Deuve, 2010. Sporades millei Giachino and S. schuhi Donabauer are newly recognized as members of the subgenus Perileptosporades, and a key to its species is provided. Although Perileptosporades can be defined monophyletically relative to the rest of the genus, genitalic variation among species assigned to the nominate subgenus Sporades Fauvel, 1882 leave monophyly of that taxon ambiguously supported. Several morphological characters of long- standing use have been proposed to define the mutual monophyly of Sporades s. l. and its putative adelphotaxon, Trechodes Blackburn, 1901. Increasing knowledge concerning the diversity of male genitalic characters among Sporades spp. lends support to a recently proposed molecular phylogenetic hypothesis positing that Sporades evolved from within Trechodes. The consequences of the alternate phylogenetic hypotheses on their attendant nomenclature are discussed. An additional locality record for S. sexpunctatus Fauvel expands the known distribution of this species to include most of Grande Terre, New Caledonia. James К. Liebherr.The species in the subgenus Amegilla (Asaropoda) are revised. Species delineation was decided based on diagnostic morphological characters as well as an incomplete phylogeny based on mitochondrial cytochrome oxidase 1 sequence data. Strong support was obtained for separating the Australian species of Amegilla into the three subgenera previously proposed on the basis of morphology. The subgenus Asaropoda was found to comprise 21 species, including ten new species A. albiclypeata Leijs, sp. nov., A. aurantia Leijs, sp. nov., A. batleyi Leijs, sp. nov., A. crenata Leijs, sp. nov., A. griseocincta Leijs, sp. nov., A. incognita Leijs, sp. nov., A. nitidiventris Leijs, sp. nov., A. scoparia Leijs, sp. nov., A. xylocopoides Leijs, sp. nov., and A. youngi Leijs, sp. nov. The subspecies A. preissi frogatti is raised to species level, and 16 new synonymies are proposed. Keys to the species of both sexes and descriptions or redescriptions are provided. Distribution maps, data on flower visitation and phenology are given. Remko Leijs, James Dorey, Katja Hogendoorn.A new leafhopper genus, Fanjinga gen. nov., with type species F. digitata Yu & Yang, sp. nov., is described from the Guizhou Province of Southwest China. Habitus photos and illustrations of male genitalia of the new species are provided. Xiaofei Yu, Rui Shi, Maofa Yang.Diestostemma bicristata sp. nov., is described from Napo Province, Ecuador. It is unusual for the genus in lacking a visible white powdery covering, having raised, weakly reticulate veins on the forewing, a short metathoracic femur (half length of the metathoracic tibia), and is the only species with a double-crested pronotum.A new parasitic species of eulimid gastropod, Haliella seisuimaruae sp. nov., is described from bathyal (728-978 m) waters off the Pacific coasts of Japan. It shows the closest resemblance to the type species H. stenostoma from the North Atlantic and Barents Sea in having a tall shell with an almost straight outer lip, but differs in having a junction of the parietal wall and columellar lip at 38% of the aperture height from the suture (33% in H. stenostoma), a slightly wider aperture and a more curved and extended columellar lip. The holotype of H. seisuimaruae sp. nov. was found attached to an irregular sea urchin, Brissopsis sp. cf. luzonica (Spatangoida Brissidae). This represents the first direct observation of parasitic ecology and echinoderm host for the genus Haliella. A new replacement name, Eulima tsushimensis nom. nov., is proposed here for Eulima stenostoma A. Adams, 1861, which is preoccupied by Eulima stenostoma Jeffreys, 1858 (type of Haliella). Tsuyoshi Takano, Shoichi Kimura, Yasunori Kano.Objective To review the theoretical benefits of airway pressure release ventilation (APRV), summarize the evidence for its use in clinical practice, and discuss different titration strategies. Data Source Published randomized controlled trials in humans, observational human studies, animal studies, review articles, ventilator textbooks, and editorials. Data Summary Airway pressure release ventilation optimizes alveolar recruitment, reduces airway pressures, allows for spontaneous breathing, and offers many hemodynamic benefits. Despite these physiologic advantages, there are inconsistent data to support the use of APRV over other modes of ventilation. There is considerable heterogeneity in the application of APRV among providers and a shortage of information describing initiation and titration strategies. To date, no direct comparison studies of APRV strategies have been performed. This review describes 2 common management approaches that bedside providers can use to optimally tailor APRV to their patients. Conclusion Airway pressure release ventilation remains a form of mechanical ventilation primarily used for refractory hypoxemia.
