Stoneflies are well known as indicators of water quality. Their presence in running waters, glacial meltwaters, and large oligotrophic lakes is rapidly declining the world over. In the USA, states partner with the U.S. Fish and Wildlife Service to protect habitat and wildlife through the development of State Wildlife Action Plans (SWAPs). Plants and wildlife species often enter these SWAPs as Species in Greatest Conservation Need (SGCN). Arkansas currently lists nine stonefly species as SGCNs and has funded research on them through SWAP grants. However, these nine species were initially chosen based on the small amount of data from a few papers. A more comprehensive assessment using museum specimen data is necessary to assess completeness of sampling, the relative rarity and endemicity of species, temporal changes in distribution, and the conservation status of species in Arkansas. Herein, we publish a data paper and preliminary dataset comprised of specimen data primarily from the Illinois Natural History Survey Insect Collection, Canadian National Collection, Western Kentucky University, P. N. Hogan Personal Collection, and from existing literature sources. These data are made publicly available by the Global Biodiversity Information Facility (GBIF) to allow for comprehensive assessment of the Arkansas Plecoptera assemblage. More recent occurrence data are needed to accurately assess imperilment of Arkansas stonefly species; these data will be provided through targeted collecting, collaboration with others in Arkansas, and through investigation of additional museum collections.
This dataset includes > 3,500 specimen records (ethanol vials or pins with or without catalog numbers) and accounts for 84 stonefly species in Arkansas, six more species than indicated in published records. Perlidae contributed 29 of these species followed distantly by Perlodidae (15), Capniidae (14), Taeniopterygidae (9), Leuctridae (7), Chloroperlidae (5), Nemouridae (4), and Pteronarcyidae (1). A species accumulation curve predicts that sampling of species is nearly complete with a Chao1 estimate of 88.0 ± 3.7 species. Our data demonstrate that 25 species are known from ≤ five records, suggesting that many more than the nine recognized stonefly SGCNs in Arkansas may meet standards for inclusion.
石蝇作为水质指标广为人知。在世界各地，它们在流水、冰川融水和大型贫营养湖泊中的数量正在迅速减少。在美国，各州与美国鱼类和野生动物管理局合作，通过制定州野生动物行动计划（SWAP）来保护栖息地和野生动物。植物和野生动物物种通常作为最需要保护的物种（SGCN）被纳入这些SWAP。阿肯色州目前将9种石蝇物种列为SGCN，并通过SWAP拨款为对它们的研究提供了资金。然而，这9个物种最初是根据少数几篇论文中的少量数据挑选出来的。有必要利用博物馆标本数据进行更全面的评估，以评估采样的完整性、物种的相对稀有性和特有性、分布的时间变化以及阿肯色州物种的保护状况。在此，我们发表一篇数据论文和初步数据集，主要由来自伊利诺伊州自然历史调查昆虫收藏、加拿大国家收藏、西肯塔基大学、P.N.霍根个人收藏以及现有文献来源的标本数据组成。这些数据由全球生物多样性信息设施（GBIF）公开提供，以便对阿肯色州襀翅目昆虫群落进行全面评估。需要更新的出现数据来准确评估阿肯色州石蝇物种的濒危状况；这些数据将通过有针对性的采集、与阿肯色州其他机构合作以及调查更多博物馆收藏来提供。
该数据集包括超过3500条标本记录（带或不带目录编号的乙醇瓶或针插标本），涵盖了阿肯色州的84种石蝇物种，比已发表记录中显示的多6种。其中，珀蝽科有29种，远多于小石蝇科（15种）、短脉石蝇科（14种）、沼石蝇科（9种）、石蚕科（7种）、氯珀蝽科（5种）、叉襀科（4种）和巨齿蛉科（1种）。物种累积曲线预测，物种采样几乎已完成，Chao1估计值为88.0±3.7种。我们的数据表明，有25个物种的记录≤5条，这表明阿肯色州符合纳入标准的石蝇SGCN可能远不止公认的9种。
