Abstract

Despite the existence of important floristic and forest inventories in the Paraná state, the montane and upper montane ecosystems still give rise to new species and new records of plants. Here, we report for the first time in the Paraná state Hydrocotyle itatiaiensis Brade (Araliaceae), a rare and poorly studied species endemic to montane and upper montane rainforests and highland grasslands of the South and Southeast regions of Brazil. The previously known geographic distribution had a 700 km gap between northern São Paulo and southern Santa Catarina states, which is now filled by the present record. We provide photographs from the field, a map of occurrences, a description, and comments on the morphology, taxonomy, and conservation status of the species. Our new records reinforce the conservation importance of these environments and the need for further floristic sur-veys in the region.

巴西南部巴拉那州天南星科植物Hydrocotyle itatiaensis Brade的首次记录

尽管巴拉那州存在重要的植物区系和森林资源，但山地和上山地生态系统仍然产生了新的植物物种和新的记录。在这里，我们首次报道了巴拉那州的Hydrocotyle itatiaiensis Brade（天南星科），这是一种罕见且研究不足的物种，原产于巴西南部和东南部地区的山地和上山地雨林以及高地草原。以前已知的地理分布在圣保罗州北部和圣卡塔琳娜州南部之间有700公里的差距，现在由目前的记录填补。我们提供了野外照片、事件地图、描述以及对该物种形态、分类学和保护状况的评论。我们的新记录加强了这些环境的保护重要性，以及该地区进一步进行植物区系调查的必要性。

期刊介绍： Check List is a peer-reviewed online journal, devoted to publishing biodiversity data related to species’ geographic distribution. Thus, our primary mission if to fill the so-called Wallacean shortfall (Lomolino 2004) and to improve our knowledge of how life is distributed on the planet in order to better preserve it. These data are essential for studies on biogeography and provide a baseline for the conservation of biodiversity. The first step to undertaking effective conservation action is to maintain records of the distribution of species. Therefore, the journal was created from the need publish basic data on species distribution of any taxon in a timely and open manner, which are often neglected by traditional journals. Check List is a bimonthly peer-reviewed online journal, and will consider for publication: -distribution summaries of a supraspecific taxon in a broad geographic area (e.g., hemisphere, country, biome), as a review of the distribution of a taxon in the given area. -annotated list of species, of a given taxon in a strict geographic area, with comments and illustrations on the identifications, based on original data. -notes on the geographic distribution, reporting new records of one or more species while providing a complete overview on the known distribution of the treated taxa. -book reviews on books related to biodiversity, biogeography, niche modeling, or any associated field that uses species distribution as its primary data source. -opinions on relevant subjects for the journal’s mission and scope
