Abstract

ABSTRACT The knowledge of the diversity and distribution of Hyalella species is scarce in the subtropical regions of Brazil. The present study investigated the diversity and distribution of Hyalella species in subtropical temporary wetlands in the southern Brazilian Coastal Plain. Six species were registered in the study region, including three new species of the genus. The spatial distribution of the species in the study region suggests that the hydrographic region (or freshwater ecoregion) is an important driver of the geographic distribution of the species. Thus, the present study increases to 19 the diversity of species with distribution in the southern region, with one new record for the state of Santa Catarina, one for the state of Rio Grande do Sul, and one for both states. We also expanded the distribution ranges of H. bonariensis, H. castroi, and H. kaingang. In addition, we elaborated a taxonomic key to the species of Hyalella known to southern Brazil. Thus, we demonstrate the need for more taxonomic studies to better understand the diversity of macroinvertebrates in Brazilian wetlands, in order to protect our fauna and contribute to the development of future conservation policies.

巴西南部沿海平原临时湿地中Hyalella属（甲壳纲：两栖目：Hyalelidae）的多样性和分布，以及该地区物种的分类关键

摘要在巴西亚热带地区，人们对透明藻物种的多样性和分布知之甚少。本研究调查了巴西南部沿海平原亚热带临时湿地中Hyalella物种的多样性和分布。研究区域共登记了6个物种，其中包括该属的3个新种。物种在研究区域的空间分布表明，水文区（或淡水生态区）是物种地理分布的重要驱动因素。因此，本研究将分布在南部地区的物种多样性增加到19种，其中圣卡塔琳娜州有一种新记录，南里奥格兰德州有一种，两个州都有一种。我们还扩大了H.bonariensis、H.castroi和H.kaingang的分布范围。此外，我们还详细阐述了巴西南部已知的Hyalella物种的分类学关键。因此，我们证明需要进行更多的分类学研究，以更好地了解巴西湿地中大型无脊椎动物的多样性，从而保护我们的动物群，并为制定未来的保护政策做出贡献。

期刊介绍： There is still a far from complete understanding of the complex ecosystems in the Neotropics, although they have been studied since the first expeditions of the old world naturalists Marcgrave, Humboldt, Spix, Darwin, Bates and Müller. The aims and scope of the Journal are, besides taxonomic and zoogeographic surveys, analyses of animal communities and their relationship with biotic and abiotic environmental conditions. This includes the fauna of both terrestrial and fresh water ecosystems in the Neotropics. Contributions that represent original research and mini-reviews are welcome. Manuscripts presenting just checklists and new geographic records are not considered for publication. If manuscripts do not meet the requirements of the journal, the editors reserve the right to reject manuscripts on submission or to ask for revisions prior to formal peer review.
